Abstract

This paper presents a study of uplink scheduling in an IP-based network for real-time service in ITS (intelligent transport system) project. Two kinds of ITS user profiles are devised and each ITS user is assumed to perform a combination of simultaneous high-speed packet data transmission and low-rate voice connection. The ITS access network is cellular orientated and based on IP transmission. The uplink traffic is queued and under different scheduling methods e.g., FIFO and priority based queuing, the transmission delay of a voice packet and Web page response time are evaluated by simulation, and thus we verify the feasibility of providing multiple parallel services in an IP-based ITS access network
