DMAC using the staggered wakeup schedule can achieve both low latency and low energy consumption. However, the data gathering tree built by DMAC is fixed permanently. A fixed data gathering tree can't adapt to the variability in the environment of wireless sensor networks, and it needs to be reconstructed frequently to suit the current environment. For example, the interference is a factor that will...
This paper proposes a user-oriented handoff system architecture to solve the detection and collection of mobile user locations using wireless sensor network (WSNs) and location-aware technologies. The proposed user-oriented seamless handoff (USH) system adopts two seamless handoff control schemes: proactive buffering (PB) as well as double queue (DQ), to minimize handoff delay and solve the packet...
