A Novel Method Based on Fuzzy Logic to Set the Arbitration Threshold in WirArb for Time Critical Applications in Wireless Sensor Network

A new method is proposed for time critical applications in wireless sensor network with strict real-time constraints that can be found in the application of industrial automation and avionics domain. Wireless Arbitration is a medium access control protocol which allows each user to access the channel based on their different levels of priority. Each user is pre-assigned a dedicated arbitration frequency which determines the channel access order and supports multiple users. Here a fuzzy logic method is proposed to set the arbitration threshold in Wireless Arbitration(WirArb) protocol This mechanism ensures that the higher priority user will immediately obtain channel access with low latency. Our result shows that the WirArb with variable arbitration threshold provides high performance to ensure deterministic communication.
