摘要：One of the wireless sensor network issues that affect heavily the network�s lifetime is the energy limitation. Minimizing energy dissipation and maximizing network lifetime in wireless sensor networks are important challenges in the design of routing protocols for sensor networks. The reason why nowadays many works are interested in WSN�s energy management, taking into account the communications and the data routing algorithms. The clustering approach is one of the techniques used to minimize energy consumption and improve the system�s life duration. In this paper, we propose a study performance of LEACH, SEP and DEEC protocols through a solid comparison of key performance parameters of wireless sensor networks such as the instability and stability period, the network lifetime, the number of cluster heads per round and the number of alive nodes. We evaluate the technical capability of each protocol vis-�-vis the studied parameters.
