> 中文摘要: 在基于IEEE 802.15.4 标准的低功耗无线传感器网络LoWPAN 中,让节点在移动过程中与IP 网络节点保持连续通信是物联网领域的一个重要课题.在现有的移动IPv6 协议(如MIPv6,HMIPv6 等)中,一些用于移动性管理的信令包长度超过了IEEE 802.15.4 MAC 帧的最大载荷,它们被分成多个分片在LoWPAN 中传递,这增大了控制信令包的丢失概率和传递时延.提出一种WoMIPv6(WPAN oriented MIPv6)协议,利用头部压缩技术将移动性管理信令长度压缩到不到60 字节,能够让节点只交换一些简短的信令包即可完成节点的跨子网移动切换.也就是说,WoMIPv6 协议的移动性管理信令不需要分片就可以在单个IEEE 802.15.4 MAC 帧中传递.此外,推导了WoMIPv6 的时延表达式.数值分析结果表明,在信令长度开销和时延方面,WoMIPv6 协议优于HMIPv6 协议.
Abstract:It is an important research area in the Internet of Things (IoT) to maintain the communication continuity between the moving Mobile Nodes (MNs) in the IEEE 802.15.4 Low-power Wireless Personal Network (LoWPAN) and the Correspondent Nodes (CNs) in the IP network. In the existing mobile IPv6 protocols, such as MIPv6, HMIPv6 etc, some Signaling Packets (SPs) for mobility management have sizes larger than the maximum payload of the IEEE 802.15.4 MAC frame so that they are fragmented into multiple pieces carried in the LoWPAN, which increases the loss probability and the delay of the SPs. The proposed WPAN oriented MIPv6 (WoMIPv6) is able to reduce the sizes of the SPs to be less than 60 B using header compression technique so that the handoff caused by the MN crossing the boundary of two successive subnets is completed after a few small sizes of SPs are exchanged. In other words, each SP in the WoMIPv6 can be carried within a single IEEE 802.15.4 MAC frame without being fragmented. In addition, the delay in the WoMIPv6 is derived. Numeric analyses show WoMIPv6 performs better than HMIPv6 both in SP size and delay.
