Design of A Self-Healing Mechanism for Wireless Sensor Networks

Abstract

A sensor network consists of multiple detection stations called sensor nodes, each of which is small, lightweight and portable. Self-healing in Sensor Networks are increasingly becoming important. Especially in wireless sensor network, interference is anything which modifies, or disrupts a signal as it travels along a channel between a source and a receiver .Successful communication occurs in a wireless sensor network only in the absence of interference which is usually achieved by assigning non- interfering channels to the pairwise links (edges) that are necessary for good connectivity To overcome this, self-healing mechanism is used when the interference occurs, while communicating with each other. In this regard designing a self-healing routing mechanism for sensor networks, which restore connectivity after a node failure. This can be achieved by using the MATLAB tool for creating a base-level accessible, open-source, real- time ad-hoc routing scheme simulations, here we are targeting the ad-hoc on-demand distance vector (AODV) routing protocol.
