Fuzzy Duty Cycle Adaption Algorithm for IEEE 802.15.4 Star Topology Networks


Abstract – IEEE 802.15.4 is a standard designed for low data rate, low powerwireless personal area networks (WPANs) intended to provide interconnection of nodesvia radio communication. Such nodes have very limited computation, energy, andcommunication capabilities. In order to extend the lifetime of the nodes, we propose afuzzy logic controller to adapt a duty cycle of each node by changing superframe order(SO) based upon the network traffic and node's buffer occupation. Simulating theproposed algorithm in Castalia simulator and comparing it with constant duty cycleschemes are carried out in this paper. Simulation results show that the proposedalgorithm decreases drop packets in node's buffer, decreases packet latency andincreases energy efficiency.
