Abstract
IEEE 802.15.6 standard is a recent standard for low power consumption, small range, and awful reliable wireless communication for Wireless Body Area Network (WBAN). Energy efficiency is a significant issue in WBAN. The sensor nodes linked to a human body are battery functioned devices and hence they have short life time. Medium Access Control (MAC) protocol for WBAN should be energy efficiency. The outdated MAC protocols emphasis on throughput and bandwidth efficiency. The major issue in WBAN is consumption of more power. By appropriately monitoring the sources of energy waste, the network life time can be maximized. In this paper, we devise an energy efficient MAC protocol in order to prolong the network life time without trading off the Quality of Service in WBANs. To study the performance in terms of the energy consumption, packet delivery ratio and end to end delay. Both baseline MAC (IEEE 802.15.6 MAC) and our devised SAMAC are evaluated by CASTALIA simulator. These simulation results show that our proposed MAC is more efficient than Baseline MAC in terms of both energy conversion and Quality of Service of WBAN.
