Research on the Strategy of Relay Selection Based on AF by Cross-layer
Zhixiong Chen · 2009
Combined with the idea of cross-layer,it proposes a relay strategy based on the MAC layer and the physical layer in amplify and forward model.This solution solves the problem on relay time.Then it gives a method on how to choose a relay and how to allocate the transmission power for the goal of minimizing the outage probability.The solution can make the selection more effective because the design of it based on cross-layer,which can make the selection based on the latest information.Further,the solution has a specific distribution of transmission power,so can use the transmission power more efficiently,and it can achieve better performance than the system of distributing power.
