Improved Security in Mobile ADHOC Networks by Enhancing the Security of Pro-Active Protocols

Security of node is an essential task in MANETS. Mobile Ad Hoc network is constructed of mobile nodes which communicate with other nodes through any wireless medium without any fixed infrastructure. Due to dynamic network topology routing in (MANETs) is a critical task due to highly dynamic environment. Security is the basic need of Ad-Hoc networks for secure communication between mobile nodes. We introduce a security scheme for pro-active (table-driven) protocols. In this security scheme we use an even-odd function. The advantage of this security scheme is to protect from any intruder or outsider node to attack or capture the node of the wireless network. We use even-odd function to make the network more secure for proactive protocols in MANETs.
