OPTIMAL RELAY NODE SELECTION USING MULTI-OBJECTIVE BASED CROW SEARCH OPTIMIZATION ALGORITHM FOR MULTIUSER COOPERATIVE COMMUNICATION NETWORKS

For Wireless sensor network (WSN), mesh network, cellular network and Ad-hoc network, cooperative relaying technique is taken into account as a crucial technique in recent times. To make the data transmission possible, the relay nodes are allocated among source and destination, in the cooperative communication network. Choosing the suitable relay node is still one of the primary issues in enhancing the cooperative communication network's performance. So as to solve this issue, a multi objective based Crow Search Optimization Algorithm (CSA) is proposed for multi user cooperative communication network. Multi objective based channel gain, power consumption and signal to noise ratio are defined in this approach to choose optimal relay node. The presented CSA algorithm functions and chooses an optimal node for relay with the fore mentioned objective functions. The proposed approach is simulated for results and these results show that the proposed approach has performed better than compared approach in terms of Throughput, SNR, lifetime of the network, Energy consumption and Delay.
