Fuzzy Based Bandwidth Management for Wireless Multimedia Networks

After finding wide range of applications in the field of communications over decades, the wired networks are replaced by mobile and wireless networks and have become ubiquitous in the recent past. This is mainly due to the dynamic nature of these wireless networks. The interesting feature of the wireless communications is the need for connectivity at any place and at any time, which leads to frequent handoff. Due to larger bandwidth of wireless communications, the cell phones are not only used to communicate voice, but also to send and receive text, video and pictures. This requires some QoS criteria such as bandwidth utilization and time delay to be managed. In this paper, we present a novel approach for designing a high performance QoS management scheme that exploits attractive features of fuzzy logic and provide adaptation to dynamic cellular environment.
