New advancements in wireless sensor networks (WSNs) make it a significant technology in research and academic community. Because of its ad-hoc and minimum infrastructure nature, it has gained lot of attention by researchers in past few years. In WSN, sensor nodes are small sized with limited energy processors which have most important task in WSN. They gather data, process it and further send it to the destination. In many applications like rescue operations, military tracking, environment monitoring etc. it is required that location of sensors must be known else the information collected gets no meaning. So, many localization algorithms are introduced in WSN which meet the resource, hardware, cost and energy constraints of WSN. Range free localization techniques are best suited for these requirements of network. DV-HOP and APIT range free techniques have gained attention in most of research efforts. So,in this paper ,performance of these techniques is evaluated on the basis of accuracy obtained while implementeing them in WSN . Detail analysis of localization error is done by considering different network parameters effecting it directly. Further structured deployment of anchors is proposed that gave more reliable results.
