A Distributed Global ID Assignment Scheme in Wireless Sensor Networks
Shin-Chih Tu · 2012
A sensor network consists of a set of sensor nodes and one or more base stations. The sensor nodes collaborate to perform sensing tasks in a given environment, and the base stations collect sensed data and possibly relay it to a central processing and storage system. Each sensor node needs unique identifier for unicast communication. In this paper, we present a scheme to assign unique ID to each sensor node. Each sensor node join the sensor network can obtain a new ID from nearly sensor node by the exchanged the messages with its neighborhood. In order to efficiently maintain the available IDs, an ID maintenance scheme is also proposed, that organizes some specific sensor nodes into a tree topology for reducing energy consumption. Simulation results show that our proposed scheme has a low latency for obtaining a new ID, and that it can efficiently maintain consistent ID pools.
