Research On The WSN Routing Protocol Based On The Context-Aware Technology

From the 1990s, the significant concept of the Ubiquitous Computing (also called pervasive computing) was addressed by the chief scientist of the Xerox PARC:Mark Weiser, then the development direction of the world computer application technology marches along this trend rapidly. The Wireless Sensor Network technology is the concrete embodiment of this thought. Pervasive computing will debase the difficulty of the equipments much and make the life of individuals easier and more efficient. Whereas the key technology needs to be solved is the technology of context-aware in its implementation. As one of the most important parts that composed of the pervasive computing in the future and the WSN technology nowadays, the research on the context-aware technology will promote the development of the present WSN technology hard and accelerate the transition from the present computer technology to the pervasive computing in the future intelligent society integrally.This paper bring in the necessity and the inevitability of the research on the WSN routing technology based on the core idea of the context-aware technology through the illustration to the inherent feature of the application routing technology in the WSN, artificial intelligence theory and the context-aware technology. To bring in the protocol CATRP the core of this paper, it merges the core idea of the context-aware technology with the traditional routing technology. And it designs the component modules and the improvement space in the aspects of the working flow, data structure, quantitative algorithm and the developed detail. As well as the innovative clustered protocol CCATRP is brought forward basing on the CATRP in this paper. This paper gives the simulation experiments of the CATRP and the CCATRP in some application scene for some performance indexes based on the physical equipment and makes contrast analysis with the same type classic protocols to gain some running specialities. At the same time, the deficiency of the protocol is proposed to solve in the solution thought.Based on the work above, this paper contend that the protocol CATRP and CCATRP as the representative which using the core idea of the context-aware technology into the basis routing protocol and transforming the traditional routing thought into positive predictable routing protocol with some artificial intelligence possess some forwarding and directive meaning. It is the correct development direction of the WSN technology in the accordance with the pervasive computing's guidance feature in the future. This paper makes the theory foundation and some contribution for the WSN technology's transition in this stage and the core protocol CATRP proposed here possesses the advantages energy efficient, theory correctness, reliable and low maintenance requirement in the concrete application can be improved and enhanced continuously by the theory circles as a fundamental protocol framework.
