Multi-node Repositioning Technique for Mobile Sensor Network

For gathering important information in Mobile sensor network, the inter-sensor connectivity represents a vital role. Nodes within these types of networks examine various aspects of an area of interest. Where failure of a sensor node may results in loss of connectivity and could result in dividing of the system into disjoint portions. Several strategies that follow node move to replace connectivity have been recently proposed. Nevertheless, these strategies often disregard the probable lack of coverage in a few areas, possibly because of the failing itself or because of the connectivity-limited concentration of the recovery. This particular paper fills the space by dealing with both the connectivity and coverage issues in an integral way. A multi-node repositioning algorithm is presented. Each and every neighbor temporarily relocates in order to replacement the particular failed node one particular at the same time and then returns back again the initial area. The algorithm is validated utilizing the efficiency parameter, distance moved and it is significance note that our algorithm handles effectively the escalation in system connectivity.
