An iterative algorithm used for node position derivation in Wireless Sensor Networks

摘要

A node position derivation algorithm called IR for WSNs is developed in this paper. IR is an iterative algorithm based on node-beacon distance information. It is assumed that each sensor node can connect with several beacons by one-hop or multihop and estimate the node-beacon distances, and then, the algorithm is executed in a distributed mode. Simulation is provided to compare our proposed algorithm with two representative position derivation algorithms, Min-max and Lateration, in terms of some evaluation parameters. The simulation shows that our proposed algorithm can be a utilitarian node position derivation algorithm for WSNs.
