Adaptive Tuning Parameters for Data Transmission over IEEE-802.15.4 Wireless Sensors Network

Abstract

Wireless sensors networks (WSNs) present the basic technology for development of such applications, as WSNs split the extra challenges of harsh environments and reduced power supply; those are the famous feature of the large use of this technology. The most difficult phase of WSNs is to provide a good quality of service (QoS) while sensing data. The problem of the medium sharing is solved by MAC protocol that provides an assumption to schedule data transmission. So, in this work, we propose a tuning strategy to dynamically perform data transmission according to the packet transmission delay and to prolong the lifetime of each sensor nodes by optimizing their energy consumption. A dynamic set of parameters for the method used to access the channel is conducted. This management is based on information about the queue length of sensor node in which a priority algorithm is made to order access to the channel according to the queue length situation. Simulation results of the proposed scheme show that this strategy performs well than the basic standard.
