ENHANCED SECURE MULTIPATH ROUTING SCHEME IN MOBILE ADHOC AND SENSOR NETWORKS

Abstract

Routing in Mobile ad hoc Sensor Network (MASNet) have become a dynamic research area owing to its impact on various science and engineering applications. A secure multipath algorithm has been presented in this research which facilitates the nodes in MASNet to execute on-demand discovery and forming set of paths. An Enhanced Secure Multipath Routing (ESMR) is formed with an adaptive behaviour on route discovery and route maintenance phase. There are two algorithms were presented in the route discovery and route maintenance phase known as DMPR and QUAD. This proposal messages are broadcasted only to limited nodes using QUAD scheme which can efficiently reduce the time to establish the path between source and destination nodes. This paper investigates the proposed algorithms with SeMuRAMAS algorithm. To achieve efficient, secure and reliable multi-path routing for MASNETs, propose a routing mechanism, which allows nodes in MASNet to perform an on-demand discovery and generation of a set of paths, based on Dynamic MPR (DMPR) protocol for route discovery process A set of security mechanisms, based on the utilization of Watchdog and digital signature, are used to protect the route discovery process. The simulation results indicate that the proposed approach provides significant performance with lesser overhead, energy efficient and better network lifetime.
