Infrastructure creation and data dissemination in WSN have traditionally been treated as independent problems. We argue that the two are tightly coupled; the former can expose key structural elements which can be exploited by the latter. This paper proposes the algorithm pair iGroup-iSpread that achieves fast and message-efficient operation by treating the(More)
Lifetime of sensor nodes determines lifetime of the network and is crucial for the sensing capability. Among the important techniques proposed for prolonging the network lifetime by exploiting redundant deployment is using hierarchical architecture or clustering. However, the primary drawback of hierarchical control is the control message overhead; it is(More)
Distributed information fusion is an active area of research; however, fusion in the large, dynamic, unpredictable, and power-scarce setting of wireless sensor network (WSN) requires more than just distributed fusion algorithms. Some of the important questions that need to be addressed are dynamic mapping of inference responsibilities to sensor nodes in a(More)
Reducing sizes and increasing capabilities of wireless communication devices as well as electronic and electromechanical systems have made it possible to not only continuously monitor a physical phenomenon by staying very close to or even inside it, but also to quickly and autonomously perform the required action upon sensing an event. Distributed,(More)
Unmanned Air Vehicles (UAVs) have crucial roles to play in traditional warfare, asymmetric conflicts, and also civilian applications such as search and rescue operations. Though satellites provide extensive coverage and capabilities crucial to many remote sensing tasks, UAVs have distinct edge over satellites in dynamic situations due to shorter revisit(More)
In Wireless Sensor Networks, nodes collaborate to perform a single task or a set of related tasks. Data generated by sensors is very often correlated. Data/decision fusion has been proposed to avoid redundant data occupying network bandwidth and consuming energy. In military setting, this suppression is required also to defeat cryptanalysis efforts by(More)
Fundamental to the problem of moving target tracking is the estimation of its state with respect to the sensing device(s). However, in sensor networks, often characterized by random ad hoc deployment possibly in inaccessible or hostile environment, the locations of the sensing devices are known only to a crude approximation. We propose ConSLAT, a smoothing(More)
