Simulation study of high speed packet radio networks

This paper describes a complete simulation model of distributed direct-sequence, multi-hop high-speed packet radio networks, which is applicable in a highly dynamic environment. In its design, the key part lies in designing the appropriate protocols and algorithms to provide reliable network transport and datagram service by dynamically determining optimal routes, effectively controlling traffic and fairly competing the channel in the face of challenging link conditions, mobility and varying traffic loads. Give the practical backgrounds of network, this model truly emulates the whole run process of network and generates many numerical results on network performance, which is very helpful to network design, management and optimization as well as person training.
