Efficient energy and QOS based routing algorithm for WBAN

In this study, a Novel architecture comprising a sink node is designed to minimize power consumption as well as improve quality of service (QoS) of wireless body area network (WBAN). It is an emerging subfield of Wireless sensor network (WSN). In the quest to enhance the network lifetime and QoS, we utilized MAC protocol to classify the physiological attributes into normal and critical data. A routing protocol known as Efficient Energy and QoS (EEQ) algorithm is implemented to transmit the normal data through the shortest and appropriate route. According to the EEQ algorithm, the weight value is considered based on parameters such as network lifetime, link stability, throughput, residual energy, packet drop and delay. The data is conveyed through the path having the highest weight value. However, the data is encrypted using RSA algorithm. In order to compare EEQ with other existing protocols, a number of simulations is executed on OMNet++ software to show that the proposed work outperforms other related research works.
