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 mobile wireless metropolitan area network (WMAN) architecture imposes a demanding power management requirement on mobile stations (MSs) in order to prolong the lifetime of MS. The base station (BS) will functionally serve as a buffer for non-real-time traffic distribution to the multiple MSs associated with it, and thus naturally provide MSs with the power saving capability. However, the power...
The seamless internetworking among various communication networks is in demand to provide anywhere, anytime connectivity with high data rate and enhanced service quality. In this paper, we propose a novel internetworking architecture between WLAN and UMTS cellular networks, hybrid coupling with radio access system (HCRAS), based on IPv6, mobile IP, and fast hand off techniques. Inheriting loose coupling...
