Wireless Sensor networks (WSNs) are mostly deployed in hostile environments,
where nodes may do not have any information about their location. Hence, the
designed routing protocols and applications have to function independently
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 focus on preserving the energy consumption.
In contrary to the existing DHT-based protocols that interconnect nodes
independently of their physical proximity, this paper 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 extends the network longevity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
