Adaptive Reservation MAC Protocol for Voice Traffic in Wireless Ad-Hoc Networksand gives them high priority to send their reservation requests over data sources. The bandwidth unused by idle voice sources is rendered temporarily available for reservation. Simulation results show that the proposed scheme improves the performances of voice traffic in terms of dropping rate.

Accessing of Large Multimedia Content on Mobile Devices by Partial Prebuffering Techniqueshe new partial prebuffering techniques is designed and pretested. The accessing of prebuffered data on mobile device can highly improve response time needed to view large multimedia data. This fact can help with design of new full scale applications for mobile devices.

Robust Transmission of H.264/AVC Video Using 64-QAM and Unequal Error Protectiono content. The performance of the transmission system is evaluated under additive Gaussian noise (AWGN) conditions. The simulation results demonstrate that the proposed strategy produces a better quality of the reconstructed video data compared with a system that offers uniform protection.

Competitive Spectrum Sharing in Wireless Networks: A Dynamic Non-cooperative Game Approachk. Game theory can be used by individual selfish nodes to determine their optimal strategy for participation level in the network. Furthermore, game theory produces information about the overall nature of nodes’ interaction and system efficiency, showing how system efficiency can be improved.

Unified Charging and Billing Solution. Unified – Next Generation of Charging Systems in Mobile Netwoibers. They expect service packages that can be tailored to meet the specific demands of their personal situation, preferences and lifestyle. This requires a flexible customer-centric approach instead of the legacy historical grown and diversed system architecture and organizations of CSPs.

An Optimization Approach to Coexistence of Bluetooth and Wi-Fi Networks Operating in ISM Environmentzation of ISM environment consisting of BT and Wi-Fi networks. To achieve it, the Integer Linear Programming approach has been proposed. Example results presented in the paper illustrate significant benefits of using the proposed modeling strategy.

Performance Analysis of IEEE 802.15.3 MAC Protocol with Different ACK Policesoughput, efficient bandwidth utilization, and delay with various acknowledgment schemes under different parameters. Also, some important observations are obtained, which can be very useful to the protocol architectures. Finally, we come up with some important research issues to further investigate the possible improvements in the WPAN MAC.
