摘要: Cooperative communications is widely used to share the resources of different nodes, and achieve spatial diversity gain in multi-user network. The node which chosen as cooperative (cluster-head), consumes more transmit power for other nodes than itself. Because this, traditional algorithm results uneven distribution. In this paper, we propose a new called weighted clustering based on distribution (PDWCA) solve problem. Compared with (WCA), proposed adds weight factor decided by reward, evaluates contributed or service others so guarantee uniform also give definition measure mobility clear one. Simulations show that performances are similar WCA terms cluster-head number load balancing (LBF); meanwhile, it can reach much better improvement average power.
