Multi-objective-Based Lion Optimization Algorithm for Relay Selection in Wireless Cooperative Communication Networks Anand Ranjan, O. P. Singh, G. R. Mishra, and Himanshu Katiyar Abstract In recent years, the cooperative relaying technique is considered as an important technique for mesh network, wireless sensor network (WSN), ad hoc network and cellular network. In this cooperative communication network, relay nodes are allocated between source and destination for facilitating the data transmis- sion. Still the selection of relay node is one of the main challenges for improving the performance of cooperative communication network. So, in this paper, a multi- objective-based lion optimization algorithm (LOA) is presented for multiuser coop- erative communication network. For optimal relay node selection, multi-objective functions based on signal-to-noise ratio (SNR) and channel gain in addition to power consumption are defined in this approach. With these objective functions, LOA algo- rithm executes and selects an optimal relay node. The simulation result shows the developed approach efficiency evaluation regarding SNR, lifetime of the network and energy consumption.
