The imminent growth of user-centric, pervasive sensing environments promotes sink mobility in an increasing number of event-based, sensor network applications including rescue missions, intrusion detection, and smart buildings. In these settings, one of the most critical challenges toward supporting quality of service, is effective distributed congestion avoidance. Congestion control techniques have...
The next generation broadband wireless access networks are expected to support a variety of multimedia rich applications which can lead to very high traffic demand. With the development of high speed radio access technologies the backhaul network can become the bottleneck if not upgraded and configured optimally to support the expected increase in date rates and traffic demands. To deliver high data...
The idea of mobile computing service is to provide a ubiquitous information environment. However, the present mobile ad hoc networks still can't support real-time transmission very effectively. In other words, the capability of supporting QoS guarantee has become a very important issue. IEEE 802.11 PCF adopts the polling scheme to provide time-bounded traffic services, which is not suitable in multihop...
