A New Scheme for Secured on Demand Routing

A Mobile Adhoc Network (MANET) is characterized by mobile nodes, multihop wireless connectivity, Non infrastructural environment and dynamic topology. A recent trend in Ad Hoc network routing is the reactive on-demand philosophy where routes are established only when required. Stable Routing, Security and Power efficiency are the major concerns in this field. This paper is an effort to achieve security solutions to achieve more reliable routing. The ad hoc environment is accessible to both legitimate network users and malicious attackers. The proposed scheme is intended to incorporate security aspect on existing protocol AODV. The study will help in making protocol more robust against attacks to achieve stable routing in routing protocols. Keywords: Ad hoc Networks, Modified AODV, AODV, Performance evaluation
