Abstract: A radio frequency based wireless technology through which the nodes are interconnected with sensor or actuator capabilities placed within or on the human body is called WBAN (Wireless Body Area Network). A network that is designed to sense the conditions of human body and pass the sensed information to base station is called wireless body area network. Due to such unique property of the network channel sensing and energy consumption are the major issues. In this research, channel sensing in wireless body area network is studied. The protocol called ELBPQA is studied which assigns priority to the data for the transmission. The ELBPQA protocol assign priority to data packets but clocks of the sensors are not synchronized which affect its efficiency. To improve performance of ELBPQA protocol, the clocks of sensor nodes are synchronized using time lay technique. The improved ELBPQA protocol and already existing ELBPQA protocol, are compared in terms of throughput, packet loss and number of dead nodes. The performance of proposed protocol is high as compared to ELBPQA protocol. It is analyzed that when the clocks of sensor nodes are synchronized then the Packet Delivery Ratio is optimized up to 8%, power consumption is reduced by 5%, delay is reduced up to 5%  and throughput is improved by 10%.

Keywords: Time-lay, Clock Synchronization, ELBPQA, WBAN
