摘要: 6LoWPAN是基于IEEE802.15.4标准的低功耗有损无线传感器网络承载IPv6协议的适配层技术。在6LoWPAN网络中,传感节点通过网关与Internet进行数据交互,导致靠近网关的节点与其他节点相比,能耗和负载严重不均衡。当前的6LoWPAN传感器网络协议不支持多网关路由功能。提出了一种基于rank值最小的多网关选择算法,在不增加额外信令的条件下,对现有6LoWPAN协议增加了多网关的支持,设计完成了6LoWPAN多网关系统方案,并在实际平台下实现。结果分析表明,该设计方案能够获得预期功能和性能,实现6LoWPAN节点能够自由选择网关,与Internet无缝互联互接。

Abstract: 6LoWPAN is an adaptation layer for carrying IPv6 in IEEE802.15.4 based low power and lossy wireless sensor networks. In 6LoWPAN, sensor nodes communicate with Internet through the gateway, around where the nodes have serious imbalance on energy consumption and load compared with other nodes. Currently, 6LoWPAN protocol is not supported by multi-gateway routing yet. In this paper, it proposes a multi-gateway selection algorithm and routing protocol based on the minimum value of rank evaluated by “Ripple” routing protocol(RPL). Without adding extra signaling, multi-gateway support is increased in the existing 6LoWPAN. Under this scheme, the multi-gateway 6LoWPAN is implemented on physical platform at last. Results show that the system can obtain desired effects and performance, 6LoWPAN nodes can choose the gateway freely, and connect with the Internet seamlessly.
