NETWORK LIFETIME AND ENERGY MAXIMIZATION USING CMAC PROTOCOL DESIGN.

By using the relay based hand off schemes a new protocol design is introduced called Cooperative Medium Access Control (CMAC), which helps the entire network schema to improve its performance and lifetime. This protocol helps the relay nodes to move from one region to another region to provide the details for communication between two nodes from one region into another. This type of complicated medium access interactions induced by relaying and leverages the benefits of such cooperation we need this mentioned CMAC protocol design. In this system a novel cross-layer distributed energy-adaptive location-based CMAC protocol is proposed, namely RODEL-CMAC, for Mobile Ad-hoc Networks (MANETs), which helps the network to improve the performance of the MANETs in terms of network lifetime and energy efficiency. Efficient relay based methodology amplifies the transceiver’s (acts as source as well as destination) energy while communicating with destination, because the relay easily traverse between each regions and gets the shortest transmission range between one another and finds the destination node ability to receive the packets from source. A distributed utility-based best relay selection strategy is incorporated, which selects the best relay based on location information and residual energy. In the simulation, the proposed work shows that the proposed RODEL-CMAC significantly prolongs the network lifetime under various circumstances even for high circuitry energy consumption.
