碩士 === 輔仁大學 === 電子工程學系 === 98 === This thesis applies concept of pheromone in the routing and positioning issues of wireless sensor networks. Under the considerations of cost and energy, most sensor nodes of a wireless sensor network do not equip with GPS (global position system) receiver. However event positioning is essential in most of the applications of wireless sensor networks. This thesis proposes a distributed and scalable pheromone routing scheme to distribute pheromone and build routing toward data center for wireless sensor networks. Through the proposed pheromone intensity distributed by routing scheme, an event positioning scheme, denoted as pheromone positioning, is also designed. Only three reference points are required for the pheromone positioning. Simulation results demonstrate that the accuracy of position of the proposed pheromone positioning is proportional to the sensor density of the wireless sensor network. Simulation results reveal that pheromone routing obtains routes close to shortest path routing but provides better robustness than shortest path routing. The routing information is also help to locate event positions. Simulation results show that higher sensor node density better precision.
