Future sensor networks will be composed of a large number of densely deployed sensors. A key feature of such networks is that their nodes have a limited battery power and they are unattended. Consequently, energy efficiency is an important design consideration for these networks. In this paper, we propose a Distributed Energy-efficient Clustering Hierarchy Protocol (DECHP), which distributes the energy dissipation evenly among all sensor nodes to improve network lifetime and average energy savings. The performance of DECHP is then compared to clustering-based schemes such as Low-Energy Adaptive Clustering Hierarchy (LEACH), LEACH-Centralized (LEACH-C), and Power-Efficient Gathering in Sensor Information Systems (PEGASIS). Simulation results show that DECHP reduces overall energy consumption and improves network lifetime over its comparatives.
