Wireless Body Area Networks (WBANs) consist of a number of miniaturized wearable or implanted sensor nodes that are employed to monitor vital parameters of a patient over long duration of time. For medical applications, these devices are placed or implanted inside the human body to measure and transfer the real time data or audio signals. Resource efficiency is one of the most important factors that should be considered when developing a MAC protocol in WBAN. There are different approaches used

Here explains a comprehensive survey of recent medium access control (MAC) Protocols for wireless body area networks (WBANs).Finally, we suggested that hybrid protocol is more useful to achieve high energy efficiency.

Peer-review under responsibility of the organizing committee of RAEREST 2016 Recently several medium access control protocols for the wireless sensor network have been proposed by the researchers using different approaches. We have studied the basic categories of MAC protocol; Contention Based, Collision Free, Scheduling Based and Hybrid in terms of reliability, latency, QoS and energy efficiency. Although several designs may have good energy efficiency and delay performance, for real time service support, there are still many challenges. The Hybrid MAC protocols show better and efficient features for real time applications but there are still many more challenges that need to be solved in the sensor networks there is still need to find out the suitable solution for real time communication and energy efficiency.
