Abstract
Wireless sensor networks (WSNs) are composed of tiny sensors nodes with limited resources, and communicating together to monitor the environment. Sensor nodes are usually powered by battery. Consequently, the energy efficiency is critical for the lifetime of the Wireless sensors network. Routing protocols are the most important issue for WSNs. LEACH (low energy adaptive clustering hierarchy) is one of the first hierarchical routing algorithms for WSNs. LEACH-C (LEACH-centralized) is a variant of LEACH where the cluster heads are selected by the Sink. At the beginning of each round in LEACH-C, the sensor nodes must send information about their current energy to the Sink, which exhausts the sensor node battery. This paper proposes an improved LEACH-C algorithm in which, the Sink uses a consumption mode for each sensor node (CMSN) to estimate the amount of energy needed for the next rounds; so, sensor nodes doesn’t have to send the value of the current energy to the Sink at the beginning of each round. The simulation results and analysis show that our proposed protocol achieve much better performances in terms of energy dissipation and network lifetime compared to LEACH-C.
