Spectrum and Network Management Convergence for Wireless Communications
白書
The main objective of this work is to study the spectrum-network management convergence that enables spectrum efficiency while providing adequate Quality of Service (QoS) required for mission critical applications running on a wireless communication network. We combine well known QoS frameworks with the different dynamic frequency (channel) allocation approaches for spectrum management to devise mechanisms that can enable efficient spectrum-network management in wireless networks with Joint Tactical Radio ystem (JTRS)-like nodes. Specifically, we present two schemes: the first is “GreedyDiffServ” scheme which is based on DiffServ and the opportunistic (greedy) approach for dynamic frequency allocation. The second scheme is “Shared Information-IntServ” which is based on IntServ and the shared information approach for dynamic frequency allocation. These two mechanisms are implemented in the QualNet network simulator on a hierarchical wireless mobile ad hoc network using “JTRS-like” devices and are evaluated against an extensive set of notional scenarios. We present simulation results that highlight the advantages of deploying a spectrum-network management scheme in a wireless network and compare the performance of the two mechanisms.
