Evaluation of novel intelligent wireless pushing mechanism based on AHP

The huge data traffic demand is a challenge for the next generation of wireless network. Since the majority of data is public information, a novel wireless intelligent pushing mechanism is presented by pushing public information in the way of point to multipoint (P2M) in network idle time, using limited spectrum. Analytic Hierarchy Process (AHP) is employed to establish the performance evaluation model, with the aim to determine the optimal bandwidth allocation strategy. It was indicated that the system spectrum efficiency (SE) increased obviously when the information overlap rate reached a certain value. And the user experienced data rate in network busy period improved significantly with pushing bandwidth increased, while the data rate degrading in idle period. AHP model helped to achieve the balance between the system performance of idle time and that of busy time.
