商品描述
In the last few years, there has been extensive research activity in the emerging area of Intermittently Connected Mobile Ad Hoc Networks (I.C.M.A.N.s). By considering the nature of intermittent connectivity in most real word mobile environments without any restrictions placed on users' behavior, I.C.M.A.N.s are eventually formed without any assumption with regard to the existence of a end-to-end path between two nodes wishing to communicate. It is different from the conventional Mobile Ad Hoc Networks (M.A.N.E.T.s), which have been implicitly viewed as a connected graph with established complete paths between every pair of nodes. For the conventional M.A.N.E.T.s, mobility of nodes is considered as a challenge and needs to be handled properly to enable seamless communication between nodes. However, to overcome intermittent connectivity in the I.C.M.A.N.s context, mobility is recognized as a critical component for data communications between the nodes that may never be part of the same connected portion of the network. This comes at the cost of addition considerable delay in data forwarding, since data are often stored and carried by the intermediate nodes waiting for the mobility to generate the next forwarding opportunity that can probably bring it close to the destination. Such incurred large delays primarily limit I.C.M.A.N.s to the applications, which must tolerate delays beyond traditional forwarding delays. I.C.M.A.N.s belong to the family of delay tolerant networks (D.T.N.s). However, the unique characteristics (e.g., self-organizing, random mobility and ad hoc based connection) derived from M.A.N.E.T.s distinguish I.C.M.A.N.s from other typical D.T.N.s such as interplanetary network (I.P.N.) with infrastructure-based architecture. By allowing mobile nodes to connect and disconnect based on their behaviors and wills, I.C.M.A.N.s enable a number of novel applications to become possible in the field of M.A.N.E.T
商品描述(中文翻譯)
在過去幾年中,間歇性連接的移動自組網(Intermittently Connected Mobile Ad Hoc Networks,簡稱 I.C.M.A.N.s)成為一個新興領域,並進行了廣泛的研究活動。I.C.M.A.N.s 考慮到大多數現實世界移動環境中的間歇性連接特性,並且不對用戶行為施加任何限制,因此最終形成了 I.C.M.A.N.s,而不假設希望進行通信的兩個節點之間存在端到端的路徑。這與傳統的移動自組網(Mobile Ad Hoc Networks,簡稱 M.A.N.E.T.s)不同,後者被隱含地視為一個連接圖,並在每對節點之間建立了完整的路徑。對於傳統的 M.A.N.E.T.s,節點的移動性被視為一個挑戰,需要妥善處理,以實現節點之間的無縫通信。然而,為了克服 I.C.M.A.N.s 中的間歇性連接,移動性被認為是節點之間數據通信的關鍵組成部分,這些節點可能永遠不會成為同一連接部分的一部分。這會導致數據轉發的延遲增加,因為數據通常由中介節點存儲並攜帶,等待移動性產生下一個轉發機會,這可能使其接近目的地。這種產生的大延遲主要限制了 I.C.M.A.N.s 的應用,這些應用必須容忍超過傳統轉發延遲的延遲。I.C.M.A.N.s 屬於延遲容忍網絡(Delay Tolerant Networks,簡稱 D.T.N.s)的一類。然而,來自 M.A.N.E.T.s 的獨特特徵(例如,自組織、隨機移動和基於自組網的連接)使 I.C.M.A.N.s 與其他典型的 D.T.N.s(如基於基礎設施的行星間網絡,Interplanetary Network,簡稱 I.P.N.)區分開來。通過允許移動節點根據其行為和意願連接和斷開,I.C.M.A.N.s 使得在 M.A.N.E.T. 領域中出現許多新穎的應用成為可能。
