Bandwidth Management Method for Heterogeneous Wireless Network

چکیده
The integration of heterogeneous networks is a trend of Fourth Generation (4G) systems. But with more integrating network technologies, bandwidth management is more complicated. This paper proposes a bandwidth management method, called Bandwidth Management and Disposition (BMD). The BMD calculates the Reword Point (RP) to quantify the Mobile Host’s (MH) requests, and calculates the Upgrade Rank (UR) or Downgrade Rank (DR) to quantify the upgraded or downgraded sequence of bandwidth, respectively. In the future, when a new service type or network technology is created, the proposed system functions also can be directly applied. This paper analyzes the BMD is more feasible than the other existed methods. The simulated results also demonstrate the functionality of the BMD. The incremental rate of achieved request is 12.52% and rate of bandwidth usage is 2.4% when the system with BMD. We conclude that the proposed system facilitates further development of wireless communication networks.

متن کاملImproving Bandwidth-power Efficiency of Homogeneous Wireless Networks Using On-meet Threshold Strategy (RESEARCH NOTE)
Over two decades, a problem of location dependent has been focused for improving the communication Bandwidth-Power Efficiency of homogeneous networks. The efficiencies of communication links are weakened by the Hidden Terminal Problem. Thus we propose a Fine – Tune Strategy for analyzing the On-Off communication region. We were observed that the proposed technique had been able to track and mo...
