Time Synchronization is the most important component in wireless sensor network (WSN). Since, it improves energy efficiency, lifetime, robustness, precision and so on. The final goal of WSN is Smart Dust. So, WSN devices can't use expensive crystals. Although diversity algorithms were proposed for Time Synchronization, most of the algorithm have(More)
We consider a cellular system with two-level hierarchy, where RSVP resource reservation is made newly over the two-hop link between the macro-level base station and the mobile host during a handoff. For wireless access networks, we propose a dynamic resource allocation scheme that adapts to variations in handoff attempts, where a macro-cell provides(More)
