Evaluation of Transport Layer Protocols Over Wireless Multihop Networks

Free registration required

Executive Summary

In a Wireless Multi-hop Network (WMN), numerous QoS mechanisms such as routing, topology control protocol and Transport Layer Protocols (TLPs) have been proposed. The focus of this paper is on the TLPs. TLPs are responsible for connection establishment and attempt to ensure that all data are transmitted from source to target destination safely. Performance of Traditional TLP (such as TCP) deteriorates in WMNs. Traditional TLPs assume that all packets losses are due to network congestion, whereas the WMN can be greatly affected by other causes such link and route failure, route changes, and medium contention in a shared environment with an increasing network size.
