摘要/Abstract

摘要：

It becomes challenging in order to represent, discover and exchange location information in a ubiquitous environment due to dynamic movement and interaction between mobile nodes inside. In this paper, a new method is presented in order to make location information context-aware so that organizing the format of location information and maintaining the communication between direct connected nodes in a ubiquitous environment is enabled. The structure of a contextual location information repository and a context information communication protocol is manipulated to implement the proposed features. According to the simulation results in network simulator version2 (NS2), the new method has depicted good discovery success and consumed efficient service discovery bandwidth. Other network traffic, i.e. transmission control protocol, (TCP) has been simulated in the scenarios but the new location-aware method has shown its robustness with continuous context discovery process.
