Available in PDF, EPUB and Kindle. Book excerpt: Self-Organization in Sensor and Actor Networks explores self-organization mechanisms and methodologies concerning the efficient coordination between intercommunicating autonomous systems.Self-organization is often referred to as the multitude of algorithms and methods that organise the global behaviour of a system based on inter-system communication. Studies of self-organization in natural systems first took off in the 1960s. In technology, such approaches have become a hot research topic over the last 4-5 years with emphasis upon management and control in communication networks, and especially in resource-constrained sensor and actor networks. In the area of ad hoc networks new solutions have been discovered that imitate the properties of self-organization. Some algorithms for on-demand communication and coordination, including data-centric networking, are well-known examples. Key features include: Detailed treatment of self-organization, mobile sensor and actor networks, coordination between autonomous systems, and bio-inspired networking. Overview of the basic methodologies for self-organization, a comparison to central and hierarchical control, and classification of algorithms and techniques in sensor and actor networks. Explanation of medium access control, ad hoc routing, data-centric networking, synchronization, and task allocation issues. Introduction to swarm intelligence, artificial immune system, molecular information exchange. Numerous examples and application scenarios to illustrate the theory. Self-Organization in Sensor and Actor Networks will prove essential reading for students of computer science and related fields; researchers working in the area of massively distributed systems, sensor networks, self-organization, and bio-inspired networking will also find this reference useful.

Available in PDF, EPUB and Kindle. Book excerpt: Wireless Sensor and Actor Networks (WSANs) are gaining growing interest because of their suitability for mission-critical applications that require autonomous and intelligent interaction with the environment. Hazardous application environments make actors susceptible to physical damage. Failure of a critical (i.e. cut-vertex) actor partitions the inter-actor network into disjointed segments while leaving a coverage hole. Maintaining inter-actor connectivity and coverage is extremely crucial in most applications of WSANs where actors have to quickly plan an optimal coordinated response to detected events. This book presents a series of localized novel algorithms that pursue controlled movement of existing (internal) actors to restore the lost connectivity while minimizing the impact on coverage. The performance of proposed approaches is analyzed and validated through extensive simulations. Simulation results confirm the effectiveness of proposed approaches that outperform the best contemporary schemes found in literature. This book should be useful for university students, researchers, faculty members, application designers and people from industry.

Download or read book Detecting and Connecting Disjoint Sub networks in Wireless Sensor and Actor Networks written by Fatih Senel and published by . This book was released on 2008 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wireless Sensor and Actor Networks (WSANs) can be considered as a combination of a sensor network and an actor network in which powerful and mobile actor nodes can perform application specific actions based on the received data from the sensors. As most of these actions are performed collaboratively among the actors, inter-actor connectivity is one of the desirable features of WSANs. In this thesis, we propose a novel distributed algorithm for establishing a connected inter-actor network topology. Considering initially disjoint sets of actors, our algorithm first initiates a search process by using the underlying sensor network in order to detect the possible sub-networks of actors in the region. After these sub-networks are detected, our algorithm pursues a coordinated actor movement in order to connect the sub-networks and thus achieve inter-actor connectivity for all the actors. This coordinated movement approach exploits the minimum connected dominating set of each sub-network when picking the appropriate actor to move so that the connectivity of each sub-network is not violated. In addition, the approach strives to minimize the total travel distance of actors and their messaging cost in order to extend the lifetime of WSAN. We analytically study the performance of our algorithm. Extensive simulation experiments validate the analytical results and confirm the effectiveness of our approach.

This book was released on 2008 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: In most of the Wireless Sensor and Actor Network (WSAN) applications, the locations for the actors are determined autonomously by the collaboration of actors and/or sensors in order to eliminate human intervention as much as possible. In this thesis, we propose an actor-CH location matching algorithm which will detect the CH locations and assign the actors to such locations in a distributed manner with the minimized travel distance. We adapt the Gale-Shapley (G-S) stable matching algorithm from Matching Theory in order to prevent conflicts and minimize the travel distance. We evaluated the performance of our approach through simulation and have shown that our approach can produce results very close to the brute force approach.

This book was released on 2014-11-27 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work is about Wireless Sensor and Actor Networks (WSANs) consist of a large number of heterogeneous nodes known as sensors and actors. Sensor nodes have lower cost, lower power, multifunctional devices that can communicate untethered in limited distances, while actor nodes are resource rich, having higher processing and transmission capabilities, equipped with additional devices and longer battery life, they collect and process sensed data and perform the appropriate actions on the environment. In WSANs, the distributed sensing of a physical phenomenon is possible with the collaborative operation of the sensor nodes. Whenever a sensor node detects an event in the deployment region like fire, earth quake, etc the event information is transmitted to the actor nodes. The actors gather, process, and take a prompt decision to react. WSANs are distributed control systems usually designed for a quick response to sensed information with an effective and timely action. For this purpose it is essential to provide a real time communication and coordination framework to ensure prompt execution of action at right location.

Book excerpt: The evolution from WSNs, which can be thought of as performing only read operations, to WSANs, which can perform both read and write operations, introduces unique and new challenges that need to be addressed. The focus of this research is to investigate these unique problems that arise in the context of a WSAN environment, and design energy- and resource-efficient network protocols best suited to this environment. Specifically, in this research, we investigate problems from three different perspectives: (i) operation correctness, (ii) resource optimality, and (iii) operation performance. Addressing the problems on these three fronts provides the basis for effective operation of WSANs.

Download or read book Communication and Coordination in Wireless Multimedia Sensor and Actor Networks written by Tommaso Melodia and published by . This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Wireless Sensor and Actor Networks (WSANs) are distributed systems of heterogeneous devices, referred to as sensors and actors, which sense, control, and interact with the physical environment. Sensors are low-cost, low-power, multi-functional devices that communicate untethered in short distances. Actors are resource-rich devices that collect and process sensor data and consequently perform actions on the environment. This thesis is concerned with coordination and communication problems in WSANs, in datacentric and multimedia application scenarios. First, communication and coordination problems are jointly addressed in a unifying framework for the case of static actors. A sensor-actor coordination model is proposed, based on an event-driven partitioning paradigm. Sensors are partitioned into different sets and each set is associated with a different actor. Data delivery trees are created to optimally react to the event and timely deliver event data with minimum energy expenditure. The optimal partitioning strategy is determined by mathematical programming, and a distributed solution is also proposed. Furthermore, the actor-actor coordination problem is formulated as an optimal task assignment problem, and a distributed solution of the problem based on an analogy with a one-shot auction is presented. Application scenarios for WSANs with mobile actors are then studied. A location management scheme is introduced to handle the mobility of actors with minimal energy consumption for resource-constrained sensors. The proposed scheme, which is the first localization scheme specifically designed for WSANs, is shown to consistently reduce the energy consumption with respect to existing localization services for ad hoc and sensor networks. An optimal energy-aware forwarding rule is then derived for sensor-actor communication in fast varying Rayleigh channels. The proposed scheme allows controlling the delay of the data-delivery process based on power control, and reacts to network congestion by diverting traffic from congested to lightly-loaded actors. The mobility of actors is coordinated to optimally accomplish application-specific tasks, based on a nonlinear optimization model that accounts for location and capabilities of heterogeneous actors. The research challenges for delivery of multimedia traffic in wireless sensor and actor networks are then outlined. Finally, a cross-layer communication architecture based on Ultra Wide Band communications is described, whose design objective is to reliably and flexibly deliver QoS to multimedia applications in WSANs, by carefully leveraging and controlling interactions among layers according to application requirements. Performance evaluation shows how the proposed solution achieves the performance objectives of wireless sensor and actor networks.
Download or read book Maximizing Connected Coverage Via Controlled Actor Relocation in Wireless Sensor and Actor Networks written by Srinivas Janapala and published by . This book was released on 2008 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wireless Sensor and Actor Networks (WSANs) have emerged recently with the idea of combining Wireless Sensor Networks (WSNs) and Mobile Ad Hoc Networks (MANETs). In addition to resource constrained sensors, resource rich and mobile actor nodes are employed in WSANs. These actors can collect data from the sensors and perform appropriate actions as a result of processing such data. To perform the actions at all parts of the region in a timely manner, the actors should be deployed in such a way that they might be able to communicate with each other and cover the whole monitored area. In this thesis, we propose a distributed actor deployment algorithm that strives to maximize the coverage of actors without violating the connectivity requirement. We present two techniques for creation of such an actor tree which are based on local pruning of the actor links and spanning tree of the inter-actor network.

Download or read book Sensor Coverage and Actors Relocation in Wireless Sensor and Actor Networks WSAN written by Praveen Kumar Nagilla and published by . This book was released on 2010 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wireless Sensors and Actor Networks (WSAN) have a wide variety of applications such as military surveillance, object tracking and habitat monitoring. Sensors are data gathering devices. Selecting the minimum number of sensors for network coverage is crucial to reduce the cost of installation and data processing time. Actors in a WSAN are decision-making units. They need to be communicating with their fellow actors in order to respond to events. Therefore, the need to maintain a connected inter-actor network at all times is critical. In the Actor Relocation Problem (Chapter 2) of this thesis we considered the problem of finding optimal strategies to restore connectivity when inter-actor network fails. We used a mixed integer programming formulation to find the optimal relocation strategies for actors in which the total travel distance is minimized. In our formulation we used powers of the adjacency matrix to generate constraints that ensure connectivity. In the Sensor Coverage Problem (Chapter 3) we developed a mixed integer programming model to find the minimum number of sensors and their locations to cover a given area. We also developed a bi-level algorithm that runs two separate optimization algorithms iteratively to find the location of sensors such that every point in a continuous area is covered.
Download or read book Distributed Recovery of Actor Failures in Wireless Sensor and Actor Networks written by Aravind Thimmapuram and published by . This book was released on 2008 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wireless sensor and actor networks (WSANs) additionally employ actor nodes within the wireless sensor network (WSN) which can process the sensed data and perform certain actions based on this collected data. In most applications, inter-actor coordination is required to provide the best response. This suggests that the employed actors should form and maintain a connected inter-actor network at all times. However, WSANs often operate unattended in harsh environments where actors can easily fail or get damaged. Such failures can partition the inter-actor network and thus eventually make the network useless. In order to handle such failures, in this thesis we present a connected dominating set (CDS) based partition detection and recovery algorithm. The idea is to identify whether the failure of a node causes partitioning or not in advance. If a partitioning is to occur, the algorithm designates one of the neighboring nodes to initiate the connectivity restoration process. This process involves repositioning of a set of actors in order to restore the connectivity. The overall goal in this restoration process is to localize the scope of the recovery and minimize the movement overhead imposed on the involved actors. The effectiveness of the approach is validated through simulation experiments.
