Packet delay analysis in wireless sensor networks using fountain code enabled-DCF

Abstract

Many applications currently exploit wireless sensor networks for long term data gathering, ranging from environmental sensing, etc., and many more are under development. This paper introduces an analytical model to investigate the delay analysis for the Fountain-Code-Enabled–Distribution Coordination Function (FCE-DCF) for the IEEE 802.11 protocol in the Wireless Sensor Networks (WSN). The state transition of buffering queue data in node is described by a two-dimensional Markov chain model. The delay is developed by extending the throughput analysis introduced by our model. This study is validate by comparison with the result obtained by Bianchi’s model. The packet delay analysis results present as a function of a number of station, packet size and the effects of contention windows are obtained using DCF for asynchronous packets transmission with four-way handshaking technique.
