本論文提出了EcoExec，支援與無線感測平台遠端互動的執行框架。EcoExec做為一個高度互動的框架，提供了許多新穎的功能，包括：(1)主機端協助的遠端感測器軟體控制及設定；(2)控制感測器系統及應用程式的程式語言和命令列介面(Command line interface)；(3)整合高度互動，具彈性的物件導向程式語言以支援感測器應用的開發；(4)腳本支援(Script-assisted)的函式動態載入機制(Dynamic loading)。 EcoExec是主從式架構(Client/Server architecture)的無線感測網路；伺服器端是無線感測器，而客戶端則是主機(Host PC)。使用者可以透過主機存取無線感測器的資訊及服務，控制並設定無線感測器的系統及應用程式。EcoExec所瞄準的是資源受限、體積極小的無線感測器。一般來說，如此的裝置因為先天的資源不足，只能支援最基本的功能。在正常的情況下，進階的功能無法在記憶體如此受限的類似平台上支援。 EcoExec將大部分的資訊儲存在資源豐富的主機端上，讓各個無線感測器可以把寶貴的記憶體空間保留給重要的功能。所有複雜的運算都在主機端完成，無線感測器只需支援簡單且有效率的遠端程式控制、傳輸、以及記憶體存取功能即可，盡量將記憶體空間保留給應用程式。本論文所提出的框架大幅度的減少測試無線感測器所需耗費的心力與時間，並且讓無線感測器應用的開發能夠更迅速、更輕鬆。本 論文描述了EcoExec框架的設計理念、實作細節、以及實驗結果。

This thesis presents EcoExec, an execution framework that supports over-the-air interactions with wireless sensor nodes. EcoExec aims to be a highly interactive framework that offers a number of novel features, including: (1) host-assisted remote control and reprogramming of sensor node applications; (2) a scripting language and a command line interface for manipulating the sensor node at both system and application levels; (3) an interactive, highly dynamic object-oriented programming language for facilitating application development; (4)script-assisted dynamic loading of functions. The EcoExec framework targets ultra compact wireless sensor nodes that are severely resource-constrained by empowering them with feature-rich functionalities that would otherwise be prohibitive on similar-scale platforms due to their inherent memory constraints. This framework cuts effort in experimenting with these platforms, thereby dramatically speeding up application development for wireless sensor nodes. This thesis describes our design concepts, details of the implementation, and experimental results.
