Bandwidth Allocation For Wireless Multimedia Traffic By Using Fuzzy Logic

Abstract

This paper presents a fuzzy based bandwidth allocation method by using bandwidth borrowing scheme for multimedia wireless networks in the context of future generation cellular networks. In the proposed scheme, bandwidth is borrowed from the applications that are already running in a cell for the new/handoff calls based on the fuzzy parameters such as application priority, age of the connection and bandwidth allocated during the connection time. The scheme guarantees that no connection gives up more than its fair share of bandwidth. The scheme has been extensively simulated for its operation effectiveness. The simulation results show that fuzzy based bandwidth borrowing scheme performs better than the traditional rate borrowing scheme in terms of call dropping, call rejection and bandwidth utilization
