Abstract-In this research work, an exploration is done for identification of critical technical issues, problems, challenges in area of wireless body network sensors, which are continuous emerging as integral part of health monitoring systems. All this is possible due to the concept of 'Internet of Things' [5], in which day to day consumer devices, equipment are connected onto the network enabling information gathering and management of many vital signals. The first section gives introduction to wireless network developments in recent context, and then it is followed by discussion on existing work done in context of physical, Media access control and other aspects like energy consumption and security of such systems. The tabular summary on the gaps, limitations of Wireless body area network is done and based on this work; future directions are also suggested. Care has been taken to solicit high impact general paper for conducting this systematic study.

In this research work we have proposed a machine to machine model of authentication. This model is applicable where multiple electronic devices are working continuously 24 hours for monitoring and periodically need to have authentication proving their identity and to remain the member of the network . The proposed work is implemented on health care devices. These devices form the "internet of medical devices "or simply body sensor networks connected with internet backbone. The proposed security measures include implementation of Zero proof Key based authentication scheme to protect the network from getting compromised. The efficacy of the proposed algorithm shows that the algorithm proposed is better in terms of Hardening measures.
