【 摘 要 】

A power allocation technique based on simultaneous perturbation stochastic approximation is devised for wireless sensor networks. Power is such allocated in source and relay that at receiver the desired combined signal strength is attained. The behaviour of the proposed technique is evaluated in a modified simple carrier sense multiple access-collision avoidance-based access control mechanism along with the greedy forwarding approach. Results show the superior performance of the cooperative relay scheme both in throughput and energy gain.
