在無線感測環境中，無線遠端更新協定是很重要的議題。當感測器散佈在網路中時，我們必須要確定每一個感測器能夠透過無線接收到應用程式的更新。在這篇論文中，我們在自己設計的第一代感測器(Octopus I)上實作三個最近提出的安全程式更新協定。這三個安全程式更新協定的作業系統使用的是微型作業系統(TinyOS)，三種協定都是在洪水(Deluge)程式更新協定上建立安全機制。因此我們需要把微型作業系統 (TinyOS)和洪水(Deluge)程式更新協定移植到我們設計的感測器平台(Octopus I)上。最後，我們使用我們的感測平台來展現三種安全程式更新協定的效能。 Remote reprogramming protocol is an important issue in wireless sensor networks. As a remote code is distributed to the networks, we need to be sure that each sensor node can receive the remote code securely through wireless medium. In this paper, we implement three recently proposed secure reprogramming protocols on our self-designed sensor nodes, named Octopus. The three secure reprogramming protocols are implemented on TinyOS with Deluge reprogramming protocol. Therefore, we need to port the TinyOS and Deluge protocol on our Octopus platform. Finally, we present the performance of the three reprogramming protocols executed on Octopus sensor nodes.
