A survey on wireless body area network: Security technology and its design methodology issue

Wireless body area sensor networks (WBANs) are becoming more popular and great potential of the human body is shown in real time monitoring. Cost-effective, unobtrusive and unsupervised continuous monitoring applications like surveillance, as well as the promise of WBANs Healthcare has attracted a wide range of activity and rehabilitation system game. However, the benefits of WBANs, using a number of challenging issues must be resolved. In addition to the open issues in standardization, WBANs energy efficiency and quality of service (QoS), security and privacy issues are major concerns. These wearable system life-critical data should be protected, since they control. Nevertheless, these systems face some difficulties of addressing security. WBANs wireless sensor networks (WSN) to inherit the most well known security challenges. However, WBANs, the specific symptoms such as severe resource constraints and harsh environmental conditions, security and privacy challenges the pretending to support additional unique. In this paper, survey the leading security and privacy issues and will survey potential attacks WBANs. In addition, we have an unsolved problem is that quality service is a serious security issue has great potential for currency in WBANs will explain, and then we discuss a potential future direction.
