碩士 === 國立雲林科技大學 === 資訊工程系碩士班 === 101 === Wireless sensor network in industrial environment (denoted IWSN) requires low data delivery time from sensor node to sink node. Due to the dynamic routing and transmission collision, the data delivery time in IWSN is unpredictable. From the power consumption point, the sensor nodes which close to the sink node incur more power consumption for forwarding the data to sink node. In this paper, a proactive routing which constructs the sensor nodes in IWSN into circular chain topology (i.e., ring topology) to avoid the data collision problem. The IWSN circular chain construction problem is converted to the traveling salesman problem (TSP) and solved by the genetic algorithm. We also develop a heuristics algorithm to adjust the circular chain to the load-balance chain. The computer simulation results reveal that the constructed load-balance chain has the less data delivery time and more system working life time.
