Intelligent Routing Metric for Wireless Body Area Networks

Abstract

Routing in Wireless Body Area Networks (WBANs) is a critical requirement due to its dynamic behaviour. This paper proposes an intelligent framework for link cost evaluation. A suitable Quality of Service (QoS) parameters based function has been proposed. The sensors in WBANs would be capable of computing the Link Cost (LC) function based upon the current values of QoS parameters: throughput, delay of the link and residual energy of the sensor. A fuzzy logic based system is proposed at the sensor to evaluate the LC. Nodes of architecture evaluate a set of possible paths between source-terminal pairs. This LC is then used to evaluate the suitable path for the routing.
