CBHRP is a hierarchical routing protocol for wireless sensor networks that extends LEACH by introducing a cluster head-set, reducing energy consumption and extending network lifetime.

Contribution

It proposes a novel cluster head-set concept for hierarchical routing, improving energy efficiency and network longevity over existing protocols like LEACH.

Findings

CBHRP reduces energy consumption significantly.

CBHRP prolongs sensor network lifetime.

CBHRP outperforms LEACH in energy and time efficiency.

Abstract

A new two layer hierarchical routing protocol called Cluster Based Hierarchical Routing Protocol (CBHRP) is proposed in this paper. It is an extension of LEACH routing protocol. We introduce cluster head-set idea for cluster-based routing where several clusters are formed with the deployed sensors to collect information from target field. On rotation basis, a head-set member receives data from the neighbor nodes and transmits the aggregated results to the distance base station. This protocol reduces energy consumption quite significantly and prolongs the life time of sensor network. It is found that CBHRP performs better than other well accepted hierarchical routing protocols like LEACH in term of energy consumption and time requirement.
