Title: The Simulation Research Of The Positioning Algorithm Of The Wireless Networks.
Abstract
Wireless sensor networks (WSN),which integrate the technologies of the Micro-Electro-Mechanical System (MEMS),sensor technology, embedded computing, distributed information processing and wireless communication, can test, sense, collect, process and transfer the information of monitored objects to terminal users in real time. As the location information is vital to the testing in wireless sensor networks, determining the location of the incident and obtaining the node position, namely the positioning technique, is one of the key techniques in the wireless sensor networks, which is the prerequisite of the target identification, surveillance , tracking and many other applications of the wireless sensor networks.
Based on large amounts of literature, the thesis first of all introduces the basic concept of the wireless sensor networks and the outline of the positioning technique, then summarizes the principle, evaluation standards and classifications of the positioning algorithm. A few examples are given such as the range-based algorithm and the range-free algorithm like DV-Hop. Then C++ programming language is used to simulate the positioning process and results of the range-based algorithm.
Considering all the environmental factors and human factors like the room temperature and the beacon nodes arranged uniformly or not, the C++ programming language is used to establish the general simulation model of positioning. And the problem of indoor positioning can be solved properly with this general model, obtaining the location results within the error.
