Book Description
"The main research objective of this thesis is to address distributed target tracking for mobile sensor networks. Based on real-life limitations, we are particularly interested in mobile sensors with Limited Sensing Range (LSR). There are three possible multi-target tracking scenarios for n mobile sensors tracking m targets: i) many sensors tracking few targets n ” m (e.g. tracking high-valued targets), ii) a few sensors track many targets n “ m (e.g. the sensor coverage problem and situational awareness in a crowded airport terminal), and iii) swarms of sensors tracking swarms of targets n,m ” 1 (e.g. selflocalization of autonomous vehicles in intellegent transportation systems). First, we show that all three problems can be posed as coupled distributed estimation and control problems for mobile sensor networks. To tackle this estimation and control problem, we propose a unified theoretical framework in which every mobile agent (or sensor) has a two-fold objective: a) maintaining a safe distance (or minimum separation) from neighboring mobile agents during target tracking and b) enhancing the quality of sensed information collectively by the team of sensors to improve the performance of distributed estimation. In many real-life applications, the quality of sensed data is a function of the proximity to the target. We propose an information-theoretic measure for quality of sensed data by each sensor called the information value as the trace of the Fisher Information Matrix (FIM). This metric of quality of sensed data plays a key role in all of our proposed distributed tracking and control algorithms. We show that objective a) of any mobile agent is fundamentally a "collision-avoidance" (or "separation") objective that is a byproduct of flocking behavior for multi-agent systems [48], while objective b) for LSR-type sensors requires solving an additional control problem to enhance the collective information value of the team of agents. We refer to the latter problem as the information-driven control problem. For distributed tracking on mobile networks, we apply Information Filter and Kalman-Consensus Filter (KCF) as effective algorithms for distributed multi-target tracking on networks. The other problem of interest is the formal stability analysis of the coupled distributed estimation and flocking-based mobility-control and self-deployment algorithms for problems i) and ii). We prove that the error dynamics of the KCF and the structural dynamics of the flock of sensors from a cascade nonlinear system and provide a Lyapunov-based stability analysis of case i). We present additional theoretical results on analysis of information-driven control and tracking algoritjms for problems i) and ii) together with successful experimental results. In addition, we identify the key questions regarding problem iii) that remains the subject of ongoing and future research."

Book Description
Target tracking is an important application for wireless ad hoc sensor networks. Because of the energy and communication constraints imposed by the size of the sensors, the processing has to be distributed over the sensor nodes. This paper discusses issues associated with distributed multiple target tracking for ad hoc sensor networks and examines the applicability of tracking algorithms developed for traditional networks of large sensors. when data association is not an issue, the standard pre- predict/update structure in single target tracking can be used to assign individual tracks to the sensor nodes based on their locations. Track ownership will have to be carefully migrated, using for example information driven sensor tasking, to minimize the need for communication when targets move. when data association is needed in tracking multiple interacting targets, clusters of tracks should be assigned to groups of collaborating nodes. Some recent examples of this type of distributed processing are given. Keywords: Wireless ad hoc sensor networks, multiple target tracking, distributed tracking.

Book Description
A sensor network operates on an infrastructure of sensing, computation, and communication through which it perceives the evolution of events it observes. We propose a fusion-driven distributed dynamic network controller, called MDSTC for a multi-modal sensor network that incorporates distributed computation for in situ assessment, prognosis, and optimal reorganization of constrained resources to achieve high quality multi-modal data fusion. For arbitrarily deployed sensors certain level of data quality cannot be guaranteed in sparse regions. MDSTC reallocates resources to sparse regions; reallocation of network resources in this manner is motivated by the fact that an increased density of sensor nodes in a region of interest leads to better quality data and enriches the network resilience. Simulation results in NS-2 show the effectiveness of the proposed MDSTC.
