Analytical models in monitoring mobile packet radio devices

Abstract

A store-and-forward broadcast radio network with mobile switching nodes is considered. The problems of monitoring connectivity changes in the network and updating information in switching nodes to enable routing of messages, are addressed. Analytical models are developed for determining the fraction of time that switching nodes have correct information as a function trajectory and speed of mobility, monitoring rate, traffic load, and network topology. The problems are experimentally investigated and results of monitoring rate to obtain performance requirements are obtained.
