DV-RSD localization algorithm based on FIND in wireless sensor network

There exists faulty nodes in wireless sensor networks nodes, the existence of them can effect the localization accuracy, at the same time, traditional DV-HOP algorithm merely use the connectivity information between nodes, thus it may underutilize the proximity information available from neighborhood sensing. According to this, DV-RSD localization algorithm based on FIND is proposed in this paper. First, FIND (Faulty Node Detection for Wireless Sensor Networks) is used to detect the faulty nodes, then removing the faulty nodes from the network. We express the relative distance between neighboring nodes by RSD (Regulated Signature Distance) instead of HOP, the rest stage is the same as in DV-HOP algorithm. Finally, through algorithm analysis, we know that the algorithm is reliable, effective and facile.
