基於6LoWPAN無線近身網路的有效分群移動協定

因為裝置在人體身上的感測器有著更多樣的發展，Wireless Body Area Networks (WBAN) 有著長足的演進，並且更進一步地將TCP/IP的協定置入在感測器中。因此，為了實現終端對終端的通訊，近年來IPv6 over Low power Wireless Personal Area Network (6LoWPAN) 吸引大量的關注及討論。而另一方面，Proxy Mobile IPv6 (PMIPv6)是network-based做管理的all-IP 移動協定，以感測器的觀點上來說，PMIPV6具有能夠減少訊息傳遞的使用量的優點，因此6LoWPAN較適合在PMIPv6的網路環境下做移動管理。然而，在WBAN情境下，感測器是以群集的方式漫遊在網路中，所以為了更加減少換手延遲時間及控制訊息耗費。這篇論文提出了enhanced Router Solicitation (RS) 跟Router Acknowledge (RA) 的訊息去做換手流程。最後數學的分析跟模擬結果顯示出提出的方法確實能夠減少延遲時間及控制訊息的耗費。

The Wireless Body Area Networks (WBAN) has a huge progress since the extension of vari-ous sensors, which attached on human body or clothing. Furthermore, Sensor nodes are capable of holding TCP/IP protocol stack. Hence, IPv6 over Low power Wireless Personal Area Network (6LoWPAN) recently attracts many discussions on accomplishing the end-to-end com-munication. On the other side, Proxy Mobile IPv6 (PMIPv6) is an approach to management the network-based mobility in all-IP wireless networks. The advantage of reducing the signal-ing cost from the perspective of mobile sensors is more suitable to 6LoWPAN. However, in the WBAN environment, it is a conception of group-based network while roaming. For further reducing the handoff delay and signaling cost, this paper proposes a handoff scheme for reduc-ing the number of sending enhanced Router So-licitation (RS) and Router Acknowledge (RAck) messages. Mathematical analysis and simulation result illustrate that the proposed handoff scheme certainly reduce the handoff delay, traffic cost and gateway overhead.
