在成簇无线传感器网络中，会出现极大簇和极小簇并存的现象，从而导致整个网络的能量消耗不均衡，进而降低网络性能。通过采用邻近极大极小簇协作发送的方案，极大地均衡了网络的能量消耗，提高了通信的可靠性。仿真结果表明，基于邻近极大极小簇的协作发送方案是一种高能效协作方案，能够很好地均衡网络能量消耗，在延长网络生存周期方面具有更优越的性能。

There will be great clusters and small clusters coexistence phenomena in clustering wireless sensor networks. It results in unbalanced energy consumption of the entire network, thus reducing network performance. By using coopera-tive transmission scheme based on adjacent great cluster and small cluster, it greatly balances the energy consumption of the network and improves the reliability of communication. The simulation results show that the cooperative transmission scheme based on adjacent great cluster and small cluster is an energy-efficient collaborative program and can well balance network energy consumption, and has superior performance in prolonging the network lifetime.
