A framework for throughput measurement of IEEE 802.15.4 under the IEEE 802.11 interference working on 2.4 GHz ISM band

This paper evaluates an analytic method for throughput measurement of IEEE 802.15.4 WSN networks under the interference of an IEEE 802.11 WLAN network with help of mathematical calculations. The presence of mutual interference between IEEE 802.15.4 and IEEE 802.11 makes the packet to be lost due to collision in data packets. In this paper, the transmission phenomenon is evaluated by five different occurrences of events based on Poisson distribution to show the effect of respective 802.11 nodes on throughput of an 802.15.4 network. The MATLAB simulations have been performed for the calculated framework to check its accuracy and understanding. The theoretical expressions closely match with simulation results. This shows the effectiveness of framework.
