Performance of packet switched services in spread-spectrum radio networks

摘要

The throughput and delay of packet switched connectionless services in a fully connected single-channel spread-spectrum radio network operating under a random access scheme is considered. Firstly, a layered model and its layer services and protocols are presented. The analytical models for performance studies include the most important parameters of a spread-spectrum packet radio; the turn time, the synchronisation delay and the capture effect and some protocol time parameters. Throughput at maximum load is found and delay is studied under some independence assumptions. The models are validated by simulations.
