Group mobility in 6LoWPAN-based WSN

Group mobility in wireless sensor network (WSN) is of particular importance in many practical application scenarios. In this paper, the group mobility management in IPv6 over Low power Wireless Personal Area Networks (6LoWPAN) based WSN is considered and the application of network mobility (NEMO) protocol to support group mobility in WSN is discussed. A new network architecture supporting the integration of NEMO and 6LoWPAN-based WSN is proposed, the group mobility management mechanism and the corresponding signaling flow are discussed. Simulation results demonstrate that comparing to MIPv6, the application of NEMO protocol in 6LoWPAN reduces both the handoff latency and the energy consumption of sensor node.
