This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The number of potential applications for wireless sensor networks is immense. These networks may consist of large numbers of low cost, low power, disposable sensor nodes that can be deployed inside or close to phenomena to be monitored. The nature of these networks necessitates specific design requirements, of which energy efficiency is paramount. The limited available energy of sensor nodes is mainly drained during communication and computational processing. An energy efficient routing protocol can limit the number of message transmissions and the computational complexity of finding routing paths. Many routing protocols have been proposed for wireless sensor networks. Most of them are computationally complex, require a large number of messages to be transmitted or require that sensor nodes possess certain hardware capabilities in order to function. The objective of this dissertation was to develop a Simple Energy Efficient Routing (SEER) protocol for wireless sensor networks that is computationally simple, reduces the number of transmitted messages and does not impose any hardware prerequisites. The new routing protocol, which was developed during this research, uses a flat network structure for scalability and source initiated communication along with event-driven reporting to reduce the number of message transmissions. Computational simplicity is achieved by using a simple method for routing path selection. The SEER protocol selects the next hop for a message by choosing a neighbour that has a smaller or equal hop count to the current node. If multiple neighbours satisfy this requirement, the neighbour with the highest remaining energy is chosen as the next hop. Each node in the network has a table containing the hop count and remaining energy of each of its neighbours. Periodic messages sent through the network update these neighbour tables. SEER uses a novel approach to select the next hop of a message during routing. The protocol increases the lifetime of the network dramatically, compared to other similar routing protocols. This improvement is directly related to the reduction in the number of transmissions made by each node. The simplicity of the protocol reduces the required computational processing compared to other protocols, and at the same time makes this one of the few available protocols that does not impose hardware requirements on nodes in order to function.

Available in PDF, EPUB and Kindle. Book excerpt: Document from the year 2020 in the subject Engineering - Computer Engineering, , language: English, abstract: Sensor nodes have restricted storage, computational and energy resources, these restrictions place a limit on the types of deployable routing mechanisms. Routing protocol disseminates information that enables the sensor nodes to select routes to communicate with other nodes on the network and the choice of the route is determined by the routing algorithms. Thus the routing protocol helps the nodes to gain knowledge about the topology of the network to which it is attached directly. There are mainly two types of routing processes: one is static routing and the other is dynamic routing. In a static routing, the routing tables are set up in a static manner in the nodes. The network routes for the packet are initially set between the nodes. However, if any node on the specified route fails, the data may not reach the destination. In a dynamic routing, routing tables in the routers often change whenever the possible routes change. Dynamic routing is more suitable as the nodes in WSNs may frequently change their position and die at any moment. The routing protocols are classified into single hop and multi hop routing. In a single hop routing, sensor node directly communicates with the sink to share the gathered information. Energy consumption is high in the network using single hop protocol. In multi hop routing, data is routed through the intermediate nodes to the base station. Each node transfers sensed data to the immediate node which in turn transfers the data to the next immediate node and finally the data reaches the base station. Energy consumption in this kind of routing protocol is less and thus the lifetime of the nodes is high. The major challenge to the efficient operation of wireless sensor network lies in its ability to deliver the sensed information from the nodes to the sink within the specific time duration without the loss of data packets with high security. The sensor nodes depend on the battery source for their operation which has limited capacity. Thus the energy resource of the sensor nodes has to be used efficiently in order to increase the operational lifetime of the network.

This book was released on 2009-08 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent advances in wireless sensor networks (WSNs) have led to many new protocols specifically designed for sensor networks where energy awareness is an essential consideration. Much attention has been given to the routing protocols since they might differ depending on the applications and network architectures. This proposed work, LEACH with Maximum Lifetime Routing, is based on the objective of maximizing the system lifetime. In this algorithm, clusters are formed randomly in each time period. Cluster heads transmit data to base station via multi-hop routing. By comparison with LEACH, LEACH with Maximum Lifetime Routing has better performance in time till first node dies and total dead nodes. Furthermore, nodes die in approximately uniformly distributed locations in LEACH with Maximum Lifetime Routing; there is no one section of the environment that is not being sensed as nodes dies, as occurs in the other algorithms.

This book was released on 2014 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: In wireless sensor networks, energy is very important issue because these networks are consisting of low-power sensor nodes. The book reviews on current routing protocols and energy efficiency methods. Then, it proposes new three routing protocols to reach energy efficiency. The protocols have different priority in energy efficiency as reduction energy consumption in the nodes, prolonging network lifetime, increasing system reliability and network load balance, reduction packet delays in network. The first protocol is based on dynamic clustering and tree structure to increase network lifetime. Energy saving method is based on sleep/wake up and data aggregation schemes. In the second protocol, an intelligent routing protocol is proposed so that is based on reinforcement learning technique. Energy saving method is based on data-driven schema. The third protocol is an energy efficient routing approach so it is based on topology control, sleep/wake up and data aggregation schemes. The simulation results show that our protocols have optimizing in different parameters such as network lifetime, packet delivery, packet delay and network balance.

Available in PDF, EPUB and Kindle. Book excerpt: A wireless sensor network consists of a large number of low-power nodes equipped with wireless radio. For two nodes not in mutual transmission range, message exchanges need to be relayed through a series of intermediate nodes, which is a process known as multi-hop routing. The design of efficient routing protocols for dynamic network topologies is a crucial for scalable sensor networks. Geographic routing is a recently developed technique that uses locally available position information of nodes to make packet forwarding decisions. This dissertation develops a framework for energy efficient geographic routing. This framework includes a path pruning strategy by exploiting the channel listening capability, an anchor-based routing protocol using anchors to act as relay nodes between source and destination, a geographic multicast algorithm clustering destinations that can share the same next hop, and a lifetime-aware routing algorithm to prolong the lifetime of wireless sensor networks by considering four important factors: PRR (Packet Reception Rate), forwarding history, progress and remaining energy. This dissertation discusses the system design, theoretic analysis, simulation and testbed implementation involved in the aforementioned framework. It is shown that the proposed design significantly improves the routing efficiency in sensor networks over existing geographic routing protocols. The routing methods developed in this dissertation are also applicable to other location-based wireless networks.

Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, we propose a suite of Evolutionary Algorithms (EA)-based protocols to solve the problems of clustering and routing in Wireless Sensor Networks (WSNs). At the beginning, the problem of the Cluster Heads (CHs) selection in WSNs is formulated as a single-objective optimization problem. A centralized weighted-sum multi-objective optimization protocol is proposed to find the optimal set of CHs. The proposed protocol finds a predetermined number of CHs in such way that they form one-hop clusters. The goal of the proposed protocol is to enhance the network's energy efficiency, data delivery reliability and the protocol's scalability. The formulated problem has been solved using three evolutionary approaches: Genetic Algorithms (GA), Differential Evolution (DE) and Particle Swarm Optimization (PSO) and we assessed each of their performance. Then, a PSO-based hierarchical clustering protocol that forms two-hop clusters is proposed to investigate the effect of the number of CHs on network's energy efficiency. This protocol enhances the WSN's energy efficiency by setting an upper bound on the number of CHs and trying to minimize the number of CHs compared to that upper bound. It also maximizes the protocol's scalability by using two-hop communication between the sensor nodes and their respective CHs. Then, a centralized weighted-sum PSO-based protocol is proposed for finding the optimal inter-cluster routing tree that connects the CHs to the Base Station (BS). This protocol is appropriate when the CHs are predetermined in advance. The proposed protocol uses a particle encoding scheme and defines an objective function to find the optimal routing tree. The objective function is used to build the trade-off between the energy-efficiency and data delivery reliability of the constructed tree. Finally, a centralized multi-objective Pareto-optimization approach is adapted to find the optimal network configuration that includes both the optimal set of CHs and the optimal routing tree. A new individual encoding scheme that represents a joint solution for both the clustering and routing problems in WSNs is proposed. The proposed protocol uses a variable number of CHs, and its objective is to assign each network node to its respective CH and each CH to its respective next hop. The joint problem of clustering and routing in WSNs is formulated as a multi-objective minimization problem with a variable number of CHs, aiming at determining an energy efficient, reliable (in terms of data delivery) and scalable clustering and routing scheme. The formulated problem has been solved using two state-of-the-art Multi-Objective Evolutionary Algorithms (MOEA), and their performance has been compared. The proposed protocols were developed under realistic network settings. No assumptions were made about the nodes' location awareness or transmission range capabilities. The proposed protocols were tested using a realistic energy consumption model that is based on the characteristics of the Chipcon CC2420 radio transceiver data sheet. Extensive simulations on 50 homogeneous and heterogeneous WSN models were evaluated and compared against well-known cluster-based sensor network protocols.
