Abstract
Wireless sensor networks foray into a promising field of remote healthcare applications nowadays, where the patients can be monitored remotely through wireless body area network (WBAN). The wireless medical sensors are deployed on the subject’s body to closely monitor the person’s vital body signs and transmit the data to the intended medical service providers. But medical sensor networks like WBAN are prone to potential security issues due to the sensitiveness of medical data and the exposure of data through wireless channel. The traditional cryptographic approaches and secure routing processes put overheads on the relatively light low-capacity nodes of the wireless body area network nodes. In this paper, a trust-based security model is proposed which will consider the data freshness factor and based on that a malicious or non-eligible node can be detected. A soft security mechanism like trust-based security model evaluates each nodes trust values that direct the communication in the network.
