Abstract: For real-time health status monitoring and treatment, the development of an efficient resource management scheme is an important research issue for wireless body area network (WBAN) based medical applications. To cope with the different application requirements, the coordination of cluster head selection, dynamic medium access control mechanism (MAC) considering both critical and normal data transfer, end-to-end connectivity, data transfer to multiple processing and destination device, intermediate node selection, and proper path selection, is mandatory. In this paper, a dynamic resource assignment scheme is proposed that assigns bandwidth and medical server resources to WBAN users for data transfer without any backoff delay and selects both the cluster head node and aggregation sensor node for the aid of WBAN sensors. The evaluation results show that the proposed dynamic resource assignment scheme performs better results than the compared random assignment scheme in terms of the delay overhead, energy overhead, goodput, and network lifetime.
Keywords: WBAN; wireless body area network; resource assignment; power conservation; cluster head selection; goodput; network lifetime.
