Reconnection of Wireless Sensor Network Partitions on Multi-Agent Platform

Abstract

In wireless sensor networks, repairing partitions is of high priority. Various methods have been proposed for detecting partitions in the networks. One approach for reconnecting a partitioned network is to repair partitions using mobile nodes. For reconnecting the partitions approaches like transmission range adjustment and message ferry methods have been proposed but these are based on the degree of connectivity with neighbors. In the proposed method, we consider a partition detection system where the base station knows the position of the sensor nodes and the base station communicates with the nodes at regular intervals. The failure of the base station to communicate with a group of sensor nodes located together is the proof that some partitions have occurred. There could be two or more partitions occurring at a time and so multiple mobile nodes are to be employed. The aim of the algorithm is to coordinate among the mobile nodes and the partitioned network and to reconnect the partition. Here the safety of nodes, security of the network and scalability are considered.
