Retransmission-Based Available Bandwidth Estimation in IEEE 802.11-Based Multihop Wireless Networks
Estimating the available bandwidth in IEEE 802.11-based multi-hop wireless networks is a very difficult task due to the medium sharing among contending nodes and collisions between hidden stations. Several methods have been proposed so far for these networks to compute the available bandwidth on wireless links. If some recent solutions such as ABE and IAB now take into account collisions and their impact on the mean back-off, none considers the packet retransmissions due to collisions although these retransmissions have an impact on the available bandwidth. In this paper, the authors propose a new available bandwidth estimation for multi-hop wireless networks called RABE (Retransmission-based Available Bandwidth).
