CHEARP: Chord-based Hierarchical Energy-Aware Routing Protocol for Wireless Sensor Networks

International audienceWireless Sensor networks (WSNs) are mostly deployed in hostile en- vironments, where nodes may do not have any information about their location. Hence, the designed routing protocols and applications have to function indepen- dently from the nodes location. Moreover, extending lifetime in such networks is a critical and challenging issue, since they consist of miniaturized energy-constrained devices. The motivation of this paper is to design an energy efficient location- independent routing protocol for data delivery in WSNs. Therefore, a Chord-based Hierarchical Energy-Aware Routing Protocol (CHEARP) is developed with the fo- cus on preserving the energy consumption. In contrary to the existing DHT-based protocols that interconnect nodes independently of their physical proximity, this pa- per proposes an approximate logical structure to the physical one, where the aim is to minimize the average paths’ length. Simulation results show that the proposed solution reduces the transmission Load, minimizes the transmission delay, and ex- tends the network longevity
