A proposal of low-latency routing protocol for short-lived TCP connections in ad hoc networks

摘要

Wireless ad hoc networks are expected to be integrated with wired networks and many applications will operate over TCP/IP (Transmission Control Protocol/Internet Protocol), so many studies have been dedicated to improving the performance of TCP over ad hoc networks. However, most of these studies assumed a persistent TCP connection. This is clearly inadequate because many TCP connections are actually short-lived. For such short-lived connections, the routing latency in ad hoc networks is considerable. We describe a new routing protocol that is suitable for a network in which many TCP connections are short-lived. Through simulations, we investigate its performance and show its advantage on some other existing routing protocols.
