Adaptive Transmission Control for Improving Throughput Performance in Multi-Packet Reception-Enabled Wireless Networks

Multi-packet reception (MPR) technology makes it possible for wireless nodes to successfully receive multiple packets from simultaneous transmitters in wireless networks. As it can provide more transmission opportunities, the network throughput performance can be dramatically improved. In this paper, we propose a transmission chance adaptation strategy, which decides an appropriate level of channel access probability for each node in wireless networks. With the appropriate setting of channel access probability, the number of concurrent trans-missions would be close to MPR capability such that the throughput performance can be improved. Through extensive simulations, we show that the proposed transmission protocol outperforms the conventional IEEE 802.11 DCF mode in terms of the aggregate throughput.
