無線感測網路由許多小型的感測節點所構成，根據任務的需求，有些感測節點必須是可以移動的，以供派遣來處理特定的事件，這種由靜態節點和行動節點共同組成的網路稱為混合式感測網路。Proxy MIPv6是著名的移動管理機制之一，其所屬的行動節點不需參與移動管理的訊令傳遞。由於感測節點多是由電池供電，而且僅具備有限的資料處理能力，因此Proxy MIPv6非常適合無線感測網路。本論文提出PMIPv6-DI機制以擴展Proxy MIPv6的功能，使其適用於混合式感測網路，並進一步分析其效能。模擬結果顯示，我們所提出的PMIPv6-DI方法可以成功在混合式無線感測網路裡運作，並配合當前環境來做行動節點的移動管理，有效降低節點移動時更新位置所需要的封包個數及延遲時間。

A hybrid wireless sensor network consists of several fixed and mobile sensor nodes. Mobile nodes make the deployment more flexible in a manner that one can dispatch mobile nodes to hot-region on demand. Proxy MIPv6 is one of the well-know network-based mobility management protocols, in which the mobile node is not required to participate in any mobility-related signaling. Proxy MIPv6 can be considered as a suitable candidate to enable mobility in wireless sensor networks. In this thesis, we provide a novel scheme called PMIPv6-DI, which enhanced the proxy MIPv6 to support inter-sensor network roaming. We also analyzed the signaling cost for location update. Simulation result shows that the proposed PMIPv6-DI can be successfully performed in hybrid wireless sensor networks. Moreover, the mobility management scheme effectively reduced the signaling cost and transmission delay occurred by the movement of mobile sensor nodes.
