A Critical Review on Recent Research on Reliable Communication for Wireless Body Area Network

Recently the Wireless Body Area Network (WBAN) technology has appeared as a subcategory of wireless sensor network (WSN) to improve the quality of life. For such medical system, the improving of reliability becomes very critical research issue because the patient requires continuous monitoring via network. On the other hand, a special attention must be given to the energy consumption because the WBAN nodes must be able to operate for long duration without being recharged or replaced. In this Paper, we have carried out survey of various existing mechanisms, recent techniques and protocols used for reliable communication and energy efficiency under low delay constraints in remote patient monitoring system. This survey depicts that the existing solutions can be further modified to devise more reliable solutions.
