QoS guarantee system for wireless sensor network

Abstract

The invention relates to a service quality assurance system for a wireless sensor network. The service quality assurance system comprises a wireless sensor network, a user control server communicating and interacting with the wireless sensor network and a service quality assurance platform for implementing control and management to the network service quality. The service quality assurance platform is provided with three functional modules of service quality assessment, service quality control and service quality management, and a network interface and a human-computer interaction interface which connected with the wireless sensor network. The structure of the service quality assurance platform is simple, the platform is easy to realize and convenient for control, various performance parameters influencing the network service quality of the wireless sensor network are analyzed through the current service quality assessment system, the key factors are searched out, and the motion of the sensor network and the nodes is further controlled and adjusted. The service quality assurance system not only can be used for online assessment to the service quality of the wireless sensor network, but also can be used for the verification and the improvement of the protocol algorithm of the future wireless sensor network, thereby having very good promotion and application prospect.

Description

technical field [0001] The invention relates to a QoS guarantee technology of a network system, to be precise, relates to a service quality guarantee system of a wireless sensor network, and belongs to the technical field of a wireless self-organizing network system. Background technique [0002] The wireless sensor network was first initiated by the U.S. Defense Advanced Research Projects Agency (DARPA) for military applications, and was evaluated by the House Science Committee as a major technological breakthrough in the United States in September 1998. In order to ensure the dominant position of the United States in this advanced technology field, DARPA and NSF have successively formulated medium and long-term research and development plans. The theory and algorithm research of China's wireless sensor network started at least 3 years later than developed countries, but since 2002, under the guidance of the National Natural Science Foundation of China, a theoretical resear...
