Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Coverage and connectivity are two key properties of wireless networks, particularly wireless sensor networks (WSNs). Deploying sensor nodes to simultaneously achieve coverage and connectivity requirements is a fundamental problem in WSNs. It is insufficient to consider coverage alone when deploying a wireless sensor network; connectivity must also be considered. While moderate loss of coverage can be tolerated by WSN applications, loss of connectivity can be fatal. Moreover, since sensors are subject to unanticipated failures after deployment, it is not sufficient for a wireless sensor network to just be connected, it should be k-connected (for k> 1). In this dissertation, we propose optimal deployment patterns to achieve both full coverage and k-connectivity for k=1,2,3,4,5, and 6, respectively, and prove their optimality for all values of r_c/r_s, where r_c is the communication radius and r_s is the sensing radius. By optimal deployment patterns, we mean those patterns that can achieve desired coverage and connectivity requirements with the fewest sensor nodes. Our results' fundamentality and generality facilitate their practical applications in, e.g., wireless mesh networks and 802.15.4 networks. We discover an interesting emph{pattern mutation} phenomenon in pattern evolution as r_c/r_s continuously changes. This phenomenon has both theoretical and practical implications. We also study several practical issues in wireless sensor network deployment in this dissertation.

Available in PDF, EPUB and Kindle. Book excerpt: Overview and Goals Wireless communication technologies are undergoing rapid advancements. The last few years have experienced a steep growth in research in the area of wireless sensor networks (WSNs). In WSNs, communication takes place with the help of spatially distributedautonomoussensornodesequippedtosensespeci?cinformation. WSNs, especially the ones that have gained much popularity in the recent years, are, ty- cally, ad hoc in nature and they inherit many characteristics/features of wireless ad hoc networks such as the ability for infrastructure-less setup, minimal or no reliance on network planning, and the ability of the nodes to self-organize and self-con?gure without the involvement of a centralized network manager, router, access point, or a switch. These features help to set up WSNs fast in situations where there is no existing network setup or in times when setting up a ?xed infrastructure network is considered infeasible, for example, in times of emergency or during relief - erations. WSNs ?nd a variety of applications in both the military and the civilian population worldwide such as in cases of enemy intrusion in the battle?eld, object tracking, habitat monitoring, patient monitoring, ?re detection, and so on. Even though sensor networks have emerged to be attractive and they hold great promises for our future, there are several challenges that need to be addressed. Some of the well-known challenges are attributed to issues relating to coverage and deployment, scalability, quality-of-service, size, computational power, energy ef?ciency, and security.

Download or read book Foundations of Coverage for Wireless Sensor Networks written by Santosh Kumar and published by . This book was released on 2006 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Wireless sensor networks (WSN) promise to revolutionize the way we monitor our surroundings by enhancing our senses. Prototype systems are already being demonstrated. Several fundamental research issues, however, remain unaddressed. Sensing events being the main task of a WSN, appropriately addressing the issue of coverage is critical. In this dissertation, we make a two fold contribution on establishing a strong foundation for the issue of coverage. First, we argue that a single concept of coverage such as k-full coverage (where every point in the deployment region needs to be within the monitoring range of at least k sensors) does not fit all applications. We propose a new concept of coverage called k-barrier coverage that is appropriate for intrusion detection applications. A WSN provides k-barrier coverage} if it guarantees that every penetrating object is detected by at least k sensors before crossing the barrier of sensors. Second, we address five foundational problems for the issue of k-barrier coverage: optimal deployment pattern, critical conditions, coverage status determination, coverage restoration, and optimal sleep wakeup. The problem of optimal deployment pattern is to determine a pattern of deployment that uses the minimum number of sensors. The problem of critical conditions is to derive conditions that can be used to determine the minimum number of sensors to deploy in probabilistic deployments. The problem of coverage status determination is to determine whether a deployed WSN provides a desired quality of monitoring. The problem of coverage restoration is to determine the minimum number of sensors to deploy, and their locations, such that a desired quality of monitoring can be restored in a deployed WSN. The problem of optimal sleep wakeup is to produce a sleeping schedule for sensors that maximizes the network lifetime. We comprehensively solve four of the five foundational problems. For the problem of critical conditions, we derive the conditions for a weaker notion of k-barrier coverage, called weak k-barrier coverage. In addition, we derive critical conditions for the case of k-full coverage.

Available in PDF, EPUB and Kindle. Book excerpt: The advances in sensor design have decreased the size, weight, and cost of sensors by orders of magnitude, yet with the increase of higher spatial and temporal re- lution and accuracy. With the fast progress of sensors design and communications technique, sensor networks have also been quickly evolving in both research and practical domains in the last decade. More and more sensor networks have been - ployed in real-world to gather information for our daily life. Applications of sensor networks can be found in battle?eld surveillance, environmental monitoring, b- logical detection, smart spaces, industrial diagnostics, etc. Although the technique of sensor networks has a very promising future, many challenges are still deserving lots of research efforts for its successful applications. Thisbookisdevotedtocoveragecontrol,oneofthemostfundamentalandimportant research issues in sensor networks. The aim of the book is to provide tutorial-like and up-to-date reference resources on various coverage control problems in sensor networks, a hot topic that has been intensively researched in recent years. Due to some unique characteristics of sensor networks such as energy constraint and - hoc topology, the coverage problems in sensor networks have many new scenarios and features that entitle them an important research issue in recent years. I have done my best to include in the book the most recent advances, techniques, protocols, results, and ?ndings in this ?eld.

This book was released on 2009-08-10 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wireless sensor networks have received significant attention because of their important role and many conveniences in our lives. Indeed, the recent and fast advances in inexpensive sensor technology and wireless communications has made the design and development of large-scale wireless sensor networks cost-effective and appealing to a wide range of mission-critical situations, including civilian, natural, industrial, and military applications, such as health and environmental monitoring, seism monitoring, industrial process automation, and battlefields surveillance, respectively. A wireless sensor network consists of a large number of tiny, low-powered devices, called sensors, which are randomly or deterministically deployed in a field of interest while collaborating and coordinating for the successful accomplishment of their mission. These sensors suffer from very scarce resources and capabilities, such as bandwidth, storage, CPU, battery power (or energy), sensing, and communication, to name a few, with energy being the most critical one. The major challenge in the design process of this type of network is mainly due to the limited capabilities of the sensors, and particularly, their energy, which makes them unreliable. This book aims to develop a reader’s thorough understanding of the opportunities and challenges of k-covered wireless sensor networks, where each point in a deployment field is covered (or sensed) by at least k sensors. Following René Descartes’ most elegant methodology of dividing each difficulty into as many parts as might be possible and necessary to best solve it (Discours de la Method, 1637), this book presents a variety of theoretical studies based on percolation theory and computational geometry, as well as protocols that lead to the design of a unified framework, where connected k-coverage, sensor scheduling, and data routing and dissemination are jointly considered.

Download or read book Deployment Coverage and Network Optimization in Wireless Video Sensor Networks for 3D Indoor Monitoring written by Tisha L. Brown and published by . This book was released on 2017 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a result of extensive research over the past decade or so, Wireless Sensor Networks (WSNs) have evolved into a well established technology for industry, environmental and medical applications. However, traditional WSNs employ such sensors as thermal or photo light resistors that are often modeled with simple omni-directional sensing ranges, which focus only on scalar data within the sensing environment. In contrast, the sensing range of a wireless video sensor is directional and capable of providing more detailed video information about the sensing field. Additionally, with the introduction of modern features in non-fixed focus cameras such as the Pan, Tilt and Zoom (PTZ), the sensing range of a video sensor can be further regarded as a fan-shape in 2D and pyramid-shape in 3D. Such uniqueness attributed to wireless video sensors and the challenges associated with deployment restrictions of indoor monitoring make the traditional sensor coverage, deployment and networked solutions in 2D sensing model environments for WSNs ineffective and inapplicable in solving the Wireless Video Sensor Network (WVSN) issues for 3D indoor space, thus calling for novel solutions. In this dissertation, we propose optimization techniques and develop solutions that will address the coverage, deployment and network issues associated within Wireless Video Sensor Networks for a 3D indoor environment. We first model the general problem in a continuous 3D space to minimize the total number of required video sensors to monitor a given 3D indoor region. We then convert it into a discrete version problem by incorporating 3D grids, which can achieve arbitrary approximation precision by adjusting the grid granularity. Due in part to the uniqueness of the visual sensor directional sensing range, we propose to exploit the directional feature to determine the optimal angular-coverage of each deployed visual sensor. Thus, we propose to deploy the visual sensors from divergent directional angles and further extend k-coverage to "k-angular-coverage'', while ensuring connectivity within the network. We then propose a series of mechanisms to handle obstacles in the 3D environment. We develop efficient greedy heuristic solutions that integrate all these aforementioned considerations one by one and can yield high quality results. Based on this, we also propose enhanced Depth First Search (DFS) algorithms that can not only further improve the solution quality, but also return optimal results if given enough time. Our extensive simulations demonstrate the superiority of both our greedy heuristic and enhanced DFS solutions. Finally, this dissertation discusses some future research directions such as in-network traffic routing and scheduling issues.

Download or read book Optimal Transmission Policies for a Star Wireless Sensor Network written by Shirin Karimifar and published by . This book was released on 2010 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Composed of wireless sensors directly or indirectly connected to the information sink, a wireless sensor network is typically employed to survey a coverage area. Sensors directly connected to the information sink form a star structure. Regardless of network topology, the central star structure shoulders the burden of relaying all information that reaches the sink. Elevated traffic in this region increases mutual interference and probability of congestion, which in turn accelerate battery depletion and ultimately limits the total amount of data that reaches the sink. It is the goal of this dissertation to provide novel insight into factors that affect communication in a star wireless sensor network. The data received at the sink until the last sensor expires, referred to as the Data volume, is introduced as a suitable performance criterion for networks of limited energy sensors. Data volume takes into consideration both the network capacity and the period in which it is available. With an information theoretic approach, optimum transmit powers and scheduling policies that maximizes the data volume for a star wireless sensor network are analytical derived. While accounting for sensor processing powers, solutions for both the stationary and time-varying wireless channels are presented. Parallel solutions derived without considering processing power in the sensor model are used to emphasize its importance. The effects of processing power, initial battery energy and network size on the data volume and the activity duration of the network are discussed. Once the optimum solution is known, various methods are introduced to reduce the computational complexity of calculating it. Less computation allows calculations for larger networks and networks with more energy. Calculation shortcuts do not compromise the optimality of the solution and simulations show their significant effects. Suboptimal transmission policies that produce data volume close to the optimum scheme but require significantly less computation are also discussed. Allowing sensors that are not transmitting to enter low-activity cycles is regarded as an energy saving measure. An analytical derivation for the optimum transmission and sleep policy is presented. Simulations show that allowing sleep cycles extends sensor lifetimes and increases data volume.
