摘要
提出了一种跨层的6LoWPAN无线传感器网络移动管理方案。首先提出了6LoWPAN网络体系结构,基于该体系结构,提出了一种跨层的移动切换算法。在此算法中,网络层移动切换与链路层移动切换同时进行,在三层切换过程中,移动节点无须转交地址配置,也无须参与网络层的移动切换过程,且无须参与移动切换过程,在二层切换过程中,移动节点无须扫描所有信道,通过获取的信道信息直接进行二层切换,因此降低了切换延迟、丢包率和切换代价。
This paper proposed a cross-layer mobility management scheme for 6LoWPAN wireless sensor networks. It created the architecture for 6LoWPAN wireless sensor networks and presented the cross-layer mobility management algorithm based on the architecture. In the algorithm, the handover in the network layer （L3） and the one in the link layer （L2） were performed synchronously. A node needed neither the care-of address configuration nor the participation in the handover process in L3. Moreover, a node could perform the fast handover in L2 without scanning all the channels. Therefore, it reduces the handover delay, packet loss and handover cost.
