Alternative Priority-based Queuing for WBAN

Abstract

Wireless Body Area Network (WBAN) technology enables medical services to expand its scope. It allows medical expert to monitor physiological data of patients using wireless communication. Despite of the numerous advantages it provides, WBAN still incur issues on different metrics on quality of service (QoS) such as end-to-end delay, queuing delay, and reliability. QoS metrics of the WBAN is affected on the efficiency of its queuing system. Previous studies proposed different routing algorithms to address QoS metrics which implement multiple queues to enhance data transmission of different data types. These studies used strict priority logic which serves the highest priority queue first. However, the main problem of this approach is that lower priority data may be totally blocked by a higher priority data. This paper presents an alternative priority-based queuing to address issue on QoS metrics. The results showed that the proposed algorithm decreased the end-to-end delay and queuing delay and increased the reliability of QoS aware routing protocol. Based on the implementation result, it can be seen that the proposed algorithm can be implement on WBAN.
