摘要

This paper proposes an intra-PAN mobility management scheme for IPv6 over Low-power wireless personal area networks (6LoWPAN) on the basis of "network-based" idea. We developed a tree-like network architecture which includes coordinate nodes for packet routing. All of the control messages are designed to transmit in link layer, and the sensor nodes are free to consider care-of address and the mobile nodes are unnecessary to deal with any mobility handoff messages. The simulation results show that this scheme efficiently cuts down the signaling cost and reduces the energy consumed by fixed nodes which can extend the life time of the whole Personal area networks (PAN).
