Cross Layer Metrics for Improving Transport Protocols in Multihop Wireless Networks
The authors' work concentrates on improving the performance of transport protocols in multihop wireless networks. They present different metrics from link and physic layers to improve the performance of TCP congestion control. This paper introduces a classification of cross layer metrics used to improve the transport level. Wired and wireless (and multihop wireless) environments differ in many aspects since the medium loss rate, the shared nature of wireless channel, the throughput and the risk of disconnection between stations. Therefore, the use of the wired network predominant protocols, especially technology-independent ones of higher layers, faces challenges in keeping their performance in wireless networks.
