Delay and capacity studies for mobile ad hoc networks with transmission-group based MAC protocol

Abstract

Delay and Capacity Studies for Mobile Ad Hoc Networks with Transmission-Group Based MAC Protocol by Juntao Gao As an advanced wireless networking technology, mobile ad hoc networks (MANETs) represent a class of self-configuring and infrastructureless networks with wireless mobile nodes. As MANETs can be rapidly deployed, reconfigured and extended at low cost, they are appealing for many critical application scenarios, like disaster relief, emergency rescue, battle field communications, environment monitoring, etc. To facilitate the application of MANETs in providing Quality of Service (QoS) guaranteed services for the above scenarios, understanding the end-to-end delay performance of these networks is of fundamental importance. Available works on end-toend delay in MANETs reported either its upper bounds, or its approximations, both of which will introduce noticeable errors to end-to-end delay evaluations in these networks. However, the analytic end-to-end delay modeling for MANETs still remains elusive, which significantly hinders the development and application of such networks. To this end, this thesis devotes to the study on analytic end-to-end delay modeling for MANETs, where the commonly used Transmission-Group Based MAC protocol (MAC-TG) is adopted to address wireless channel access issues in these networks.
