Abstract
oTWLAN is a stochastic discrete event continuous time simulator developed to assist simulation based research studies of wireless ad-hoc networks. The simulator is primarily designed for analysing link layer and network layer protocol functions. However, a complex radio model is implemented to have an accurate packet capture model. oTWLAN has many similar characteristics as WLAN (IEEE 802.11), but also provides a 100kbps radio channel for enlarged radio coverage area and relaying of traffic for increased service coverage area. The network supports multi-level precedence and preemption, which is an important service in military networks and emergency networks. The first part of this document describes the networks protocols implemented and the design of the simulator. The last part focuses on validation of the simulator and presents some multihop simulation experiments.
oTWLAN er en nettverksimulator som modellerer et trådløst ad-hoc datanett. Simulatoren er utviklet for å studere nettprotokoller der prioritetshåndtering av brukertrafikk er et krav. Dette dokumentet viser eksempler på hvordan simulatoren kan brukes, men beskriver også design og realisering av simulatoren.
