Wireless sensor networks represent a very interesting field in the Internet of objects (IoT) and in information and communication technologies in view of the diversity of their applications based on the manipulation of information through sensor nodes with limited characteristics (low storage capacity, autonomous source of energy, limited power, etc.). In this kind of networks generally called WSN, hierarchical routing has shown over the last few years his increasing interest among researchers in the field of computer research aiming to guarantee energy efficiency of the network. In this paper, we compare some existing energy efficient clustering routing protocol with a new clustering protocol which we have developed during our researches using different simulation parameters, and we show that our routing protocol gives better results and extends the network lifetime.
