The localization principle and error source of DV-Hop algorithm which is classic self-localization algorithm in wireless network are introduced in this paper. Aiming at the disadvantage of DV-Hop algorithm on localization accuracy, an improved scheme by modifying the average hop distance is proposed. The simulation results show that the comprehensive properties of the improved algorithm (including...
As forest was considered as one of the most important and indispensable resources, the prevention and detection of forest fire have been hotly researched in worldwide Forest Fire Prevention Departments. Wireless sensor network (WSN) as a new technology of information acquisition and processing, has important strategic significance to improve the level of detection of the forest fire. Sensor nodes...
Wireless Sensor network(WSN), which was made by the convergence of sensor, micro-electro-mechanism system and networks technologies, was a novel technology about acquiring and processing information. Wireless sensor network (WSN) had a great application value and wide application prospect in the fields of military, agriculture, environmental monitoring, medical health, industry, intelligent transportation,...
As we all know, the forest is considered as one of the most important and indispensable resources, the prevention and detection of the forest fire, have been researched hotly in worldwide forest fire prevention departments. Based on the deficiencies of conventional forest fire detection on real time and monitoring accuracy, the wireless sensor network technique for forest fire detection was introduced,...
