ENERGY EFFICIENT AND DEFENDING AGAINST ATTACKS IN MANET USING CBDS

In mobile ad hoc networks (MANETs), a primary requirement for the establishment of communication among nodes is that nodes should cooperate with each other. In the presence of malevolent nodes, this requirement may lead to serious security concerns; for instance, such nodes may disrupt the routing process. In this context, preventing or detecting malicious nodes launching gray hole or collaborative black hole attacks is a challenges and its attempt to resolve this issue by designing a dynamic source routing (DSR)-based routing mechanism, which is referred to as the cooperative bait detection scheme (CBDS), that integrates the advantages of both proactive and reactive defense architectures and also have a tendency to concentrate on sleep planning for geographic routing in duty-cycled WSNs with mobile sensors and propose 2 geographic-distance-based connected-k neighbourhood (GCKN) sleep planning algorithms. One is that the geographic-distance-based connected-k neighbourhood for first path (GCKNF) sleep planning formula. The other is that the geographic-distance-based connected-k neighbourhood for all ways (GCKNA) sleep planning formula. Recently, the research focus on geographic routing, a promising routing scheme in mobile sensors, is shifting toward duty-cycled in which sensors are sleep scheduled to reduce energy consumption.
