CONTINUOUS NEIGHBOR DISCOVERY IN ASYNCHRONOUS SENSOR NETWORKS
Abstract:
Sensor networks are large sets of small, inexpensive devices with hardware for sensing and a radio for communication with the other sensors. Sensor networks are being enabled by the convergence of several technologies at once. The advent of cheap, low-power microprocessors, sensor technology, and low-power RF design has made it possible to conceive of large networks which can together do what might be impossible (or too costly) to do with fewer, more expensive nodes. In most sensor networks the nodes are static. Nevertheless, node connectivity is subject to changes because of disruptions in wireless communication, transmission power changes, or loss of synchronization between neighboring nodes. Hence, even after a sensor is aware of its immediate neighbors, it must continuously maintain its view, a process we call continuous neighbor discovery. In this work we distinguish between neighbor discovery during sensor network initialization and continuous neighbor discovery. We focus on the latter and view it as a joint task of all the nodes in every connected segment. Each sensor employs a simple protocol in a coordinate effort to reduce power consumption without increasing the time required to detect hidden sensors.
