LBS ontologies and its application in DTN

Abstract

Mobile networking services need the location information, especially in mobile-based DTN. In order to realize the efficient resource searching in mobile-based DTN, we need a mechanism on the basis of contextual information, which can increase the searching efficiency with searching a group of nodes using few messages. So in this paper, we propose two service ontologies for mobile-based networks, called LBSO. Additionally, we propose a Mobile-based routing protocol using the above ontology model for resource searching. While these ideas are simple, our experiments show they significantly raise the delivery rate and lower latency in a wide variety of scenarios as compared to previous approaches.
