While GPS receivers can be used for location awareness in the outdoor environment, it can be prohibitively expensive in terms of size, cost and power consumption for large scale deployment. Most of the existing work in network localization has investigated the problem of computing the locations of all nodes with the help of a limited subset of {\it seed} nodes, who are already aware of their own locations. In this work, we introduce the novel concept of mobile seed node assisted localization, in which a small subset of mobile sensor nodes are used for network localization. specifically, we consider the case in which the network is localized using only three mobile sensor nodes. We present efficient algorithms for network localization that optimizes the localization latency, total battery power and minimizes the maximal power consumption by any mobile sensor node.
