Performance Evaluation of Quality of Service Parameters for Stationary and Moving Body in Wireless Body Area Networks

In WBANs, the energy consumption and reliable communication depend on the placement of sensors on the body. It may require more energy to transmit the data in single hop communication because sometimes distance between sensor and coordinator is large. Instead of direct transmission far away sensor node uses relay sensor to forward the data for more reliable communication with less energy consumption. The position of relay sensor node depends on the situation of body i.e. moving or stationary. Transmission path of the faraway sensor node is varying because of relay choice. In this paper, we have proposed the algorithm for path selection based on the utilization factor. However, the CSMA/CA (carrier sense multiple access with collision avoidance) techniques for IEEE 802.15.6 is used to access the channel. We have compared the moving and stationary body scenario in terms of QoS parameters such as total energy consumption, total delay, packet delivery ratio and throughput. Total energy consumption is more and total delay is less in moving body. Packet delivery ratio and throughput are more in stationary body.
