E2HRC: An Energy-Efficient Heterogeneous Ring Clustering Routing Protocol for Wireless Sensor Networks

Abstract

This E2HRC: An Energy-Efficient Heterogeneous Ring Clustering Routing Protocol for Wireless Sensor Networks study presents heterogeneous ring domain communication topology with equal area in each ring in an effort to solve the energy balance issue in the original RPL. A new clustering algorithm and event-driven cluster head rotation mechanism
are also proposed based on this topology. The clustering information announcement message and clustering
acknowledgment message were designed according to RFC and original RPL message structure.An energyefficient heterogeneous ring clustering (E2HRC) routing protocol for wireless sensor networks is then
proposed and the corresponding routing algorithms and maintenance methods are established.Related
messages are analyzed in detail. Experimental results show that in comparison against the original RPL,
the E2HRC routing protocol more effectively balances wireless sensor network energy consumption, thus
decreasing both node energy consumption and the number of control messages.
