Wearable Wireless Body Area Networks

Integration of portable, energy efficient computing devices with clothing results in possibilities of wear-ware. Wearable network is composed of all these tiny interactive devices, which is highly appealing now a day's. A wearable body area network (WBAN) is the emerging technology that is developed for wearable monitoring application. WBAN revolutionized wearable computers communication with their users and I/O devices. They are based on body area networks (BAN) which operates on limited energy storage. WBAN is playing an important role to get the real time and accurate data with limited energy consumption. WBAN is created by applying a number of tiny wireless sensors strategically placed on the human body, which provides the real time data to user by monitoring the various vital signs. In this paper we present WBAN architecture, design issues and will mainly focus how this technology could help military and aerospace. Like in aerospace that integrated system in flying coverall can synergize the information from multiple sensors, warn the pilot and other users in the case of emergencies, and provide feedback during supervised recovery or normal activity. These systems consists of multiple sensor nodes that monitor body motion and heart activity, a network coordinator, and a personal server running on a personal digital assistant or a personal computer.
