The phenomenal advances in MEMS and nanotechnology make it feasible to build small devices, referred to as sensors that are able to sense, compute and communicate over small distances. The massive deployment of these small devices raises the fascinating question of whether or not the sensors, as a collectivity, will display emergent behavior, just as living(More)
Due to their potential applications in various situations such as battlefield communications, emergency relief, environmental monitoring, and other special-purpose operations, wireless sensor networks have recently emerged as a new and exciting research area that has attracted a good deal of well-deserved attention in the literature. In this work we take(More)
Neighborhood discovery (ND) in a wireless sensor network is a process of identifying the sensors that a given node can communicate directly. In this paper, our main contribution is to model the ND protocol in a wireless sensor network. In ND task, each node is assigned its own <i>N</i> timeslots, with equal slot intervals. In each slot, each node chooses(More)
Purpose – The purpose of this paper is to model an important aspect of the problem of sensor information integration that arises in wireless communications, where N sensors try to communicate with a receiver using a single un-shareable radio channel. If several sensors transmit at the same time, their transmissions collide at the receiver resulting in(More)
