Quantifying factors affecting quality of service in mobile ad hoc networks

摘要

To quantify the impact of factors and their interactions on the performance of real-time flows through statistical analysis of data gathered in simulation. Research to support quality of service (QoS) in mobile ad hoc networks (MANETs) has largely been motivated by the need to support voice communication. This is the primary application in battlefield and in emergency situations where MANETs are best deployed. What makes supporting QoS in MANETs challenging is that the network operates without any centralized control or fixed infrastructure. Frequent changes in the network topology result from node mobility and from the time-varying characteristics of the wireless channel. Such network dynamics add to the difficulty of supporting QoS (i.e., estimating and provisioning resources to real-time flows to satisfy their rate, delay, or jitter requirements).
