摘要：Recent advancements in MEMSs technology, VLSI and Wireless Private Area Networks have contributed in developing enormous interest in wireless sensor networks by both academia and research community.WSN is formed by large number of small, cheap and low energy sensors that work together in monitoring regions. WSN find its application in many areas such as object tracking, disaster relief and smart environments. Most of these applications need location awareness of sensor nodes to estimate the origin of events. Localization has remained a challenge in successful implementation of WSN and so, it is a hotspot of research. Range free localization techniques are given lot of importance in recent research works because they suit well for low cost, low energy and less infrastructure requirements of WSN and also involve lesser computation complexity. DV- HOP is one of the range free techniques that have attracted researchers' interest. In this paper, DV-HOP algorithm is implemented by deploying anchor nodes in a structured way at various radio ranges. Structured deployment of anchors give more accurate location estimates than random deployment that was followed in basic DV-HOP, which has been demonstrated in a detailed manner by the simulation results.
