Abstract

Wireless sensor networks (WSN) have become possible because of the on-going improvements in sensor technology. As the development of WSN, the problem about WSN is growing up. Sensor nodes localization is the importance a new research point. Getting the smallest location error in nodes localization is the final goal. Many work in literature propose schemes and methods for localization in wireless sensor networks. In this paper we presented a localization scheme, called the Local Hop-count Probability Grid, that is the derive algorithm of Probability Grid and can also be used in WSN which have been deployed in a grid topology.
