Autonomous Community Area Construction Technology to Achieve High Assurance

With the advancement of wireless communication, widespread devices and mobile communication technologies have realized location-aware services. In such an environment, the necessity for an effective service discovery is becoming increasingly important, but because of the static property, conventional technologies such as re-setting various TTL (time to live) face the difficulties when considering dynamic situation. In this paper, autonomous community area construction technology composed of autonomous service search technology and autonomous service area construction technology is proposed as the service retrieval technology in dynamic and distributed environment. In autonomous service search technology, the searching area is set dynamically by the response of service provider(SP) in a single request. Thus, the timeliness can be improved in the situation where location of SP is unpredictable. Autonomous service area construction technology achieves the service retrieval by adopting the idea of dynamic data caching technology. The simulation result shows the effectiveness of the technology.
