Adaptive Relay Selection Algorithm in Cooperative Communication
Yu Zhang, Wensheng Sun · 2014
Based on the traditional cooperative communications' protocol for fixed forwarding based on the research, according to a dynamic network environment for network topology changes dynamically and wireless transmission tim- ing characteristics, an adaptive transmission relay selection strategy and power allocation method was proposed. Simu- lation results showed that, compared with traditional fixed cooperative diversity, the proposed adaptive relaying scheme further improved the performance gain, bit error rate dropped significantly, and that the network life was prolonged.
