Abstract

Abstract – 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.
