Wireless body area networks: a comprehensive survey

Current progress in technology, especially wireless body area network (WBAN) became one of the enabling technologies that provide many successful applications in non-medical or medical field. WBAN is a communication standard optimised for low power devices and operation on, in or around the human body, to monitor the human health issues and route the physical or vital data from biosensors nodes to the server for further analysis. The challenge of WBAN is that the energy of the biosensors is limited by the battery life and many routing protocols have been designed specifically for relaying collected data to a base station for additional processing, it might differ depending on the network architecture. This paper based on the recent publications provides a WBAN survey.
