Repairing network partitions in Wireless Sensor Networks

Abstract

The failure of sensor nodes could hinder the usefulness and the effectiveness of a WNS. In this paper we present a method to repair network partitioning by using a mobile node. By reasoning upon the degree of connectivity with neighbours, the mobile node finds the position where to deploy new sensor nodes in order to restore the network connectivity. Factors influencing the algorithm performance are discussed. Simulations show that the proposed method is effective and efficient not withstanding packet loss
