INTRODUCTION, SYSTEM MODEL AND PROBLEM STATEMENT

Abstract

In wireless sensor networks, sensors collect data from their surroundings and forward it to the actor nodes. Actors with collaboration respond so as to achieve predefined mission. Since actors have to carry out their operation with coordination, it is required to have strongly connected network topology at every instance of time. Also the length of path between must be constrained so as to meet the latency requirement of the network. This paper represents the algorithm to curb down topology changes when a network fails and gets disjoined or partitioned. Least-Disruptive topology Repair (LeDiR) algorithm is proposed for this task of minimal topology changes and also changing the cluster head constantly to prevent the failure of the sensor due to overhead is proposed as a preventive measure. LeDiR uses the local view of a node about the network to devise a recovery plan that relocates the least number of nodes and ensures that no path between any pair of nodes is extended.
