Traffic types, protocols, and system performance in wireless networks

In the portable and mobile information age, the services delivered to the user will be primarily determined by the user. The radio and wireless network technologies used to deliver these services should enable them, not limit them. Thus, it is necessary to understand the demands of wireless products, applications, and services from a top-down, layered point of view. The objective of the paper is to discuss how to usefully model the performance of wireless applications and their protocols without having to construct models so detailed in a layer by layer sense as to be impractical
