DATA SECURITY THROUGH NODE-DISJOINT ON DEMAND MULTIPATH ROUTING IN MANETS

Mobile Ad Hoc Networks(MANETs) are the wireless networks which can be deployed instantly without requiring any fixed wired infrastructure. MANETs are specifically very much useful in military, commercial and civilian applications. Since infrastructure less MANETs have dynamic topology and battery powered mobile nodes, it is a challenging task to provide secure data transmission between any pair of nodes in MANET. Multipath on Demand Routing is one possible solution to provide security in MANET. This paper proposes a new method (DSNMR) of providing secure communication by integrating trust based mechanism with multipath on demand routing approaches in MANETs. The simulation analysis of proposed method reveals the facts that the method provides significant security to the data compared to previous related work.
