Executive Summary

Location awareness is an attractive research issue in the Wireless Sensor Networks (WSN) because sensor nodes are randomly scattered over a region and can get connected into a network on their own. However, precise location information may be unavailable due to the constraint in energy, computation, or terrain. In this paper, the authors proposed an improved DV-HOP location algorithm based on local estimating and correction in location for wireless sensor networks. Simulation experiments are conducted to compare the traditional DV-HOP algorithm, improved DV-HOP algorithm and their scheme, the simulation results show that the proposed methods has better performance on average location error based on the same total number of sensor nodes and the communication radius.
