![]() ![]() Our investigation has the potential to aid in the development of next generation WLAN MAC protocol. Proposed analytical model has been validated through extensive simulations. ![]() Effect of the number of nodes, MPR capability, contention window size, and sensing errors on the saturation throughput has been investigated. Solving the Markov chains for stationary probabilities, we derive the saturated throughput and energy efficiency of our protocol. Further a Markov chain model to capture the state of the MPR channel has been derived. A Markov chain model for the backoff process of the nodes with MPR capability has been derived. Our protocol modifies the backoff mechanism of the IEEE 802.11 DCF so that the backoff process quickly adapts to the prevailing traffic conditions while leveraging MPR. In this paper, we analyze a modified IEEE 802.11 DCF based medium access control (MAC) protocol for Wireless Local Area Network (WLAN) with nodes having MPR capability. This promising technology is called Multi-Packet Reception (MPR). Recent advances in physical layer technologies, allows simultaneous reception of multiple packets by a node. ![]()
