A New Address Scheme for Service Discovery supporting Active Mobile Sensor Objects

Recently, there are many researches on discovering sensor objects in wireless sensor network. However, most concern is to find statically deployed sensor objects by the user in IP infrastructure network. As sensor device attached with IP is introduced and bi-directional communication becomes possible in sensor network, mobile sensor object which moves to new region and needs emergency help, feels the necessity of discovering the preferred service actively. So we propose type-based address allocation to enable mobile object to discover preferred service actively in new region. Consequently, it can care resource issue of sensor object and reduce burden of building complex middleware architecture.
