Energy Efficient MAC Protocols for Wireless Body Area Networks (WBANs)

The Wireless Body Sensor Network (WBSNs) is useful in providing the medical services for people who need continuous monitoring and caring and especially aged people, which are small devices implant or placed inside the human body. It works by batteries but these batteries must have high efficiency and should work through the whole age and not be replaced unless after a long period. We will mention several MAC protocols which are used in WBSNs networks that work on increasing the efficiency of energy and reduce its loss.
