The effects of on-demand behavior in routing protocols for multihop wireless ad hoc networks

Abstract

Abstract-A number of different routing protocols proposed for use in multi-hop wireless ad hoc networks are based in whole or in part on what can be described as on-demand behavior. By ondemand behavior, we mean approaches based only on reaction to the offered traffic being handled by the routing protocol.In this paper, we analyze the use of on-demand behavior in such protocols, focusing on its effect on the routing protocol's forwarding latency, overhead cost, and route caching correctness, drawing examples from detailed simulation of the dynamic source routing (DSR) protocol. We study the protocol's behavior and the changes introduced by variations on some of the mechanisms that make up the protocol, examining which mechanisms have the greatest impact and exploring the tradeoffs that exist between them.Index Terms-Communication system routing, computer network performance, dynamic source routing (DSR) protocol, wireless ad hoc networks.

The Dynamic Source Routing Protocol (DSR) for Mobile Ad Hoc Networks for IPv4

“…The DSR protocol has been extensively studied since then through additional detailed simulations. In particular, we have implemented DSR in the ns-2 network simulator [NS-2, BROCH98] and performed extensive simulations of DSR using ns-2 (e.g., [BROCH98,MALTZ99a]). We have also conducted evaluations of the different caching strategies in this document [HU00].…”

A novel approach to source routing for multi-hop ad hoc networks

“…At the link layer we simulated the distributed coordination function (DCF) of the IEEE 802.11 Wireless LAN standard [6]. For DSR all the optimization functions described in [7], were implemented. We simulated a scenario in which 50 nodes move randomly in an area of 1000 1000 m .…”

“…Upon receiving an error packet, a host removes from its cache the parts of the routes that contain the broken link. Furthermore, by using source routing, SASR is able to take advantage of all optimization procedures proposed for DSR [7]such as salvaging, gratuitous route repair and promiscuous listening.…”
