Abstract：Aim to higher transmission power consumption of full collaborative relays and the problem of attenuation based on channel error, an original method is proposed for regional collaborative relays and relays selection based on Norm-bounded Channel Error. The regional collaborative relay networks system is analyzed and built in accordance with lowest power consumption compared with full collaborative relay, and the optimal relay selection is acquired through meeting requirement of power consumption in wireless communication. The channel error based on regional collaborative relay selection is introduced, which has characteristics of satisfying randomly Gaussian generated under bounds of norm, in order to comprehensively describe the non-deterministic factors of the channel. Then, using the theory of local relaxation and sparse lifting, convex optimization approximation solution is proposed. Simulations show that the proposed algorithm satisfies the predetermined service levels at relatively small excess transmission power and stronger robustness.
