A stochastic model is formulated and analyzed to study the advancements of messages under greedy routing in a sensor network with a power-saving sche...

The vague question "What can machines do and what can they not do?" has generated much controversy in the past, and continues to be a source of confu...

In this article, we study the critical sensor density for partial connectivity of a large area sensor network.We assume that sensor deployment follow...

Sensor network localization is an instance of the NP-Hard graph realization problem. Thus, methods used in practice are not guaranteed to find the co...

We study the problem of planning the motion of “data mules” for collecting the data from stationary sensor nodes in wireless sensor networks. Use of...
