Selection of an Efficient Next Hop Metric in Wireless Sensor Networks Using Fuzzy Logic
Wireless Sensor Network (WSN) consists of small sensor nodes that cooperate with each other to send sensed data to the Base-Station (BS). Choice of optimal next hop for data routing is really important in WSN and it acts as a significant part in preserving energy. Individual parameters or weighted metric of different parameters are used in selecting a next hop, but the selection of suitable and effectual parameters and metric is very important to improve the performance of the network. This work considers a fuzzy logic approach to evaluate the performance of network w.r.t. different weighted metrics. Performance is evaluated by adding a fuzzy logic controller to determine best next hop metric selection for routing.
