Autonomous Full-Mesh Network for Large-Scale Outdoor Sensing (Short Paper)

In recent years, large field sensing has been widely studied whereby an application for representative agricultural and disaster reduction utilizes a wireless sensor network (WSN). However, outdoor field sensing involves problems related to communication quality and distance. Particularly, the communication reliability in portable wireless sensor networks is greatly influenced by the surrounding environmental factors which affects the communication nodes´ movement. Unlike fixed wireless sensor networks, radio wave conditions are dynamic, which yields many differences such as the effects of plants. Both the performance and communication quality are addressed by proposing a full-mesh network capable of high speed re-connecting at the time of the failure. We evaluated the problems by deploying outdoor sensor nodes based on our proposed system.
