Multi-hop Auction-Based Bandwidth Allocation in Wireless Ad Hoc Networks

In a wireless ad hoc network, multiple end-to-end flows that traverse through the same wireless communication range compete for the shared wireless bandwidth. Then, how to allocate those shared bandwidth among flows is one of most critical issues for the system performance. To that end, this paper proposes an auction-based bandwidth allocation with multi-hop flow coordination mechanism to enhance various performance measures. Experimental results suggest that the proposed approach outperforms other approaches in terms of network throughput, bandwidth utilization, fairness, end-to-end delay, and packet loss rate.
