Energy-Efficient Time-Sharing Multichannel MAC Protocol for Wireless Body Area Networks

The evolution of wireless body area network (WBAN) has changed the human life for its applications in the field of health care, fitness, entertainment, sports, etc. However, two of the major challenges in the design of WBAN are energy efficiency and guaranteeing QoS. The introduction of multichannel scheme has reduced the delay and increase the throughput by allowing parallel transmission in the WBANs and biosensors. In this paper, we propose time-sharing multichannel MAC for wireless body area network with an intention for real time and guaranteed delivery of emergency data and maximize energy efficiency. The objective is to design an efficient time-sharing multichannel MAC protocol for WBANs for energy-efficient transmission with low interference. Each node has been statically allocated to the time slots and channels so that they can wake up at their time slots and transmit their data. The proposed method is simulated using Castalia to study and compare its performance with its counterparts. The simulation results reveal that the proposed protocol works better than the existing methods in terms of delay, throughput and energy efficiency.
