Problems Network may hard to self-adapt to Environment Changing. November 13 2008 Problems Network may hard to self-adapt to Environment Changing. Some Applications expect the networks with the High Reliability and Low Latency. WangPing, Wang Quan, Liang Li , Wang Qin

Device-Adaptive Channel Hopping November 13 2008 Device-Adaptive Channel Hopping Adaptive Channel Hopping Within One Slot Channel Health Report Come up Slot = (Timeslot, Channel #n, Channel #m) WangPing, Wang Quan, Liang Li , Wang Qin

Device-Adaptive Channel Hopping November 13 2008 Device-Adaptive Channel Hopping Added Slot = (Timeslot, Channel #n, Channel #m) WangPing, Wang Quan, Liang Li , Wang Qin

Summerize Advantages Cost High Reliability: Two Channel Insure November 13 2008 Advantages High Reliability: Two Channel Insure Low Latency: Retry in One Slot Self-Adaptability: Nodes do by themselves Complianced with The Solution (Timeslot, Channel #n) Flexibility: Used or Non-Used Channel utilization (hopping): Non-Used Channel could be arranged Cost One More Channel if Chosen No Cost If no Interference Only about 1ms Additional Power consumption if Interference (within 10ms Length TimeSlot) WangPing, Wang Quan, Liang Li , Wang Qin

More Detail Test Data and Simulation Result will be Shown November 13 2008 Further Work More Detail Test Data and Simulation Result will be Shown Next Meeting WangPing, Wang Quan, Liang Li , Wang Qin
