Improvising Routing and Security in MANET with Game Theory

Data throughput is spectacularly increasing by using MIMO and CR utilizes the existing wireless spectrum opportunistically. The emerging technologies tackle the problem of limited available spectrum. Combination of ad hoc networks with MIMO and cognitive radios greatly ready to merge with the networking and communication technology of decentralized architecture. Adhoc in nature the networks meets many vulnerable security attacks and need existing protocols and security mechanisms must be enhanced through efficient manner. We propose unique scheme to enhance the security for MANET routing protocol under game theoretic approach. In this paper we have to use cooperative mean theoretic game theory is used model the security game between MANET. The overall problem of securing a distributed system comprises the security of the networked environment, and the security of each individual network node. This is a challenging problem and closed-form solution with good localization accuracy has yet to be found. The proposed methodology simulated in MATLAB and the respective results are plotted.
