Time Slot Assignment for Maximum Bandwidth in a Mobile Ad Hoc Network

Time slot assignment is essential to provide the calculated bandwidth in a TDMA (Time Division Multiple Access)-based Mobile Ad hoc NETwork (MANET), which is a focus of attention of this paper because of its collision-free packet transmission with QoS (Quality of Service) support. A new time slot assignment algorithm-SAGO Slot Assignment by Global Overview) is proposed, by which more available bandwidth can be obtained than conventional approximate solutions. SAGO assigns time slots from a global overview, that is, time slot assignment is based on the usage of global information such as finding of bottleneck of a route, tentative bandwidth evaluation of a route and assignment of time slot according to the order of their free times in the concerned links.
