DEL-CMAC Protocol together with Cross-Layer Cooperative Diversity Approach to Improve the Network Lifetime of MANET

A wireless communication network is rich in interference and noise which makes the communication in the network unreliable. There has been many active research on cooperative communication which helps in improving the reliability of wireless network. To enhance the spectral and power efficiency, lifetime of the network, and reduce outage probability, cooperative communications with relaying nodes are very effective. Relaying induce complicated medium access interactions, to handle these interactions and to capitalize the benefits of cooperation an efficient Cooperative MAC protocol is required . This paper proposes, Distributed Energy-adaptive Locationbased CMAC protocol, namely DEL-CMAC along with effective cross layer cooperative diversity approach for MANET. Cross layer handles the interaction between higher layer and cooperative diversity is used for diversity gain in the network where relay nodes are used. The use of cooperative diversity in the network leads to increase in reliability in the network. The design objective of proposed work is to improve the network lifetime of MANET by reducing the power consumption and improving the throughput.
