Fault repair algorithm using localization and controlled mobility in WSN

Recent advancements in wireless communications and electronics have enabled the development of low cost sensor networks. The sensor networks can be used in various applications such as military, health, home. Depending on the application researches are resolving different technical issues. In some applications, a certain segment of the network becomes energy constrained before the remaining network. The performance gets limited to these constrained sections. In this situation, instead of rendering the complete network useless, the remaining energy sources should be reorganised to form a new functional topology in the network. Such energy constrained sections where many nodes have failed are called Network Holes. In this paper we present a new algorithm which uses controlled mobility of some nodes to fill in the holes formed in the network using localization techniques.
