Infrastructures less network is MANET which creates the temporary network. Performance and security are its two major issues. Due to its self organizing feature providing runtime network security is tedious task. So an efficient and strong model is required to setup so that various eavesdropping activity can be avoided. Key management is a vital part of security in Manet because the distribution of encryption keys in an authentication manner is a difficult task due to its dynamic nature. As every time nodes leaves or joins it has to regenerate a new session key for maintaining secrecy. In this paper, we have proposed a new key management scheme to improve the network security with less mobility overhead and less key distribution time . KeywordsManet, certificate based cryptography , symmetric keys.

“…Another category of solutions do not require multiple radios but require communication to be set up in specified time slots [9]- [11] or require periodic channel switching according to certain sequences [12]- [14]. Thus they rely on time synchronization which adds considerable complexity [15] and degrades scalability [16], especially for multi-hop networks.…”

Abstract-Distributed Information SHaring (DISH) is a new cooperative approach to designing multi-channel MAC protocols. It aids nodes in their decision making processes by compensating for their missing information via information sharing through other neighboring nodes. This approach was recently shown to significantly boost the throughput of multi-channel MAC protocols. However, a critical issue for ad hoc communication devices, i.e., energy efficiency, has yet to be addressed. In this paper, we address this issue by developing simple solutions which (1) reduce the energy consumption (2) without compromising the throughput performance, and meanwhile (3) maximize cost efficiency. We propose two energy-efficient strategies: in-situ energy conscious DISH which uses existing nodes only, and altruistic DISH which needs additional nodes called altruists. We compare five protocols with respect to the strategies and identify altruistic DISH to be the right choice in general: it (1) conserves 40-80% of energy, (2) maintains the throughput advantage gained from the DISH approach, and (3) more than doubles the cost efficiency compared to protocols without applying the strategy. On the other hand, our study shows that in-situ energy conscious DISH is suitable only in certain limited scenarios.

“…In the absence of an AP, nodes in the PS mode should synchronize among themselves in a distributed way [11], [26]. In addition, a beacon does not contain the TIM, and each sender should advertise its own packet by transmit ting an Ad hoc TIM (ATIM) frame during the packet advertisement period, called ATIM window.…”
