Cluster Based Energy Efficient Routing Protocol for Wireless Body Area Network

Abstract

Wireless Sensor Networks (WSNs) are well known due to its multiple application areas. It consists of tiny nodes, which are cheap and easyto deploy in several types of application areas ranging from industrial to health. The Wireless Body Area Sensor Networks (WBANS) arepopular in health applications and play an important role for monitoring the critical patients. Among different operations, routing is alwaysrecognized as a resource hungry operation. Therefore, it is pertinent to design an energy efficient routing protocol for WBNS. The mainaim of this study was to design a Cluster Based Body Area Protocol (CBBAP) in order to enhance the overall energy efficiency by 25% overthe existing approaches. The Base Station (BS) is placed far in our routing protocol of CBBAP, while the gateway approach is adopted,which is proposed to be placed in the centre of the sensing area. The current proposed protocol of CBBAP uses the Cluster Head (CH)mechanism as a Low Energy Adaptive Clustering Hierarchy (LEACH). The performance of the proposed CBBAP protocol was comparedwith LEACH for WBNS efficiency and found more practical for various application areas.
