✦ Synopsis

The paper describes Ethersim, a simulation tool to model and study the performance of multimedia-oriented integrated service ATM networks with mobile hosts and wireless links. The key motivation behind Ethersim is to study the application-leÕel impact of host mobility and wireless channels. Ethersim has a discrete event based simulator core and incorporates models of user applications and transport, network and MAC layer protocols. It provides the capability to specify a cellular wireless ATM network topology and host mobility patterns. The software architecture of Ethersim employs five special entities: an air module, a map, a mover, mobile hosts, and basestations. We also present case-studies of using Ethersim to model and study the interaction of transport layer, connection rerouting protocol, and radio characteristics in the w
