Modeling of TDMA-based Dynamic Slot Assignment Algorithm for Data Link
Rui Ding · Communications technology · 2011
Fixed TDMA assignment algorithm could guarantee the fairness of the traffic of every node,but it is impossible to implement slot allocation for the current state of traffic and the network,and difficult to achieve service differentiation and provide mechanisms in support of QoS.So a dynamic TDMA algorithm is proposed for TTNT data link.This TDMA-based slot assignment algorithm,with the addition of priority contention mechanism,could improve the throughput of Ad Hoc network and provide a good utilization of the radio resource,especially in high input loads environment.Simulation on the OPNET network simulation platform shows that the dynamical TDMA algorithm is better than the fixed TDMA in terms of throughput and delay.
