Hybrid routing protocol for wireless body area networks

Abstract

Healthcare is an application where the Wireless Body Area Network (WBAN), the emerging field of Wireless Sensor Network (WSN), can give assistance to the person in case of detection of abnormal activities of the human body without demanding the presence of the doctor. The small-sized sensors can be deployed for continuous monitoring of the physical activities of the human body. In the case of abnormal activity, the sensors will alert the person as well as share the data with the health expert. The information to be sent is very critical so the routing nodes selection must be done in such a manner that the malicious nodes will not get the information. There are various factors which we can count as the selection parameters for taking a node as part of the route. The Trust of the sensor node is very important as if the node is not trustworthy the chances of delivering correct data to the destination node are very less. This may lead to a threat to a person’s life. In this paper we are presenting a routing algorithm which will count the trust of the node as an important factor and update the path if it found any malicious node in between the route.
