An Efficient Routing Protocol Based on Position Information in Mobile Wireless Body Area Sensor Networks

In recent years, interests in the application of Wireless Body Area Network (WBAN) have grown considerably. Wireless Body Area Sensor networks consist of fixed sensor nodes. Sometimes, creating such a fixed sensor networks could be a daunting task. Wireless Body Area Sensor nodes assume deploying a stationary sensor network over a human body area. Even if an advanced method to make the deployment safer is used, diverse element will cause a coverage holes. Even though perfect coverage can be achieved initially, various factors such as body movements will certainly degrade network coverage as time goes on. However, mobile wireless body area sensor networks can solve some of the problems. Some node of mobile wireless body area sensor network has mobility. Mobility reinforces fault-tolerance and the scalability of the network. But conventional sensor routing protocols find it hard to deal with the mobile wireless body area sensor networks. Therefore, this study suggests an energy efficient routing scheme by using the location information of a global positioning system (GPS) and the energy levels of sensor nodes.
