中文说明：本文研究了 LEACH 协议和提出能源浸出和多跳 LEACH 协议。能源 LEACH 协议簇头选择方法作了改进，使某些节点作为簇头在下一轮有更多的剩余能量。多跳 LEACH 协议提高了从单跳到多跳簇头和接收器之间的通信模式。仿真结果表明能量浸出和多跳 LEACH 协议有更好的性能，比 LEACH 协议。
English Description：
This paper studies LEACH protocol, and puts forward energy-LEACH and multihop-LEACH protocols. Energy-LEACH protocol improves the choice method of the cluster head, makes some nodes which have more residual energy as cluster heads in next round. Multihop-LEACH protocol improves communication mode from single hop to multi-hop between cluster head and sink. Simulation results show that energy-LEACH and multihop-LEACH protocols have better performance than LEACH protocols.
