Abstract

Recently, because of the rising popularity of multimedia applications and potential commercial usage of MANET(Mobile Ad Hoc Network)s, and the limited bandwidth and dynamic topology in MANETs. providing required bandwidth for these applications in MANETs has become an unavoidable and urgent task to achieve sufficient QoS (Quality of Service). Time slot assignment is essential to provide the calculated bandwidth in TDMA (Time Division Multiple Access)- based MANETs, which are a focus of attention of this paper because of its collision-free packet transmission with QoS support. In this paper, a new time slot assignment algorithm-PBTSA (Policy-Based Time Slot Assignment) is proposed, by which more available bandwidth can be obtained than conventional approximate solutions. In addition, PBTSA's effectiveness is proved by simulation results.
