Improving network coding throughput in multi-hop networks through DCF adoption in 802.11

摘要

Wireless Multi-Hop networks often rely on the use of IEEE 802.11 technology, Regardless of the robustness of IEEE 802.11 Distributed Coordination Function (DCF) is not optimal in various network scenarios. In this study and other have experienced the inefficacy's of DCF when Network Coding is applied, therefore the room of improvement is needed to consider Network Coding technique. DCF is fairer to nodes than the process of Network Coding. Since the rely nodes in multi-Hop scenario have urgent requirements to gain more access and regulated access, which accommodate the network Coding process. We propose enhanced algorithm to DCF mechanism on MAC layer that favouring Network Coding, and guarantee to give more access to medium and better share of medium for relay nodes between bidirectional traffic flows in saturated network traffic scenario.
