Fuzzy duty cycle adaption algorithm for IEEE 802.15.4 star topology networks

Abstract EN

IEEE 802.15.4 is a standard designed for low data rate, low power wireless personal area networks (WPANs) intended to provide interconnection of nodes via radio communication.

Such nodes have very limited computation, energy, and communication capabilities.

In order to extend the lifetime of the nodes, we propose a fuzzy 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 the proposed algorithm in Castalia simulator and comparing it with constant duty cycle schemes are carried out in this paper.

Simulation results show that the proposed algorithm decreases drop packets in node's buffer, decreases packet latency and increases energy efficiency.
