摘要 無論生活在哪個世代,有限的時間內將訊息散播給最多人知道是一件非常重要的事情。由於部分訊息具有時效性,當訊息過期後才獲得為時已晚,故有效率訊息散播的方法是熱門的研究議題。
本文深入探討在虛實網路環境下訊息散播的方法,首先第一個研究主題探討在耐延遲網路環境下節點的移動模型,節點之間的實體相遇頻率會影響評估訊息散播的機會。若要評估訊息散播的方法適不適合在真實社會中使用,需要真實的移動模型來進行模擬,較可推估及預測在真實社會下訊息的發酵需要多久時間。
第二個研究主題則是評估訊息散播方法需考量到接收者對於訊息是否感興趣,回顧過往的研究大多著重在訊息傳遞給一個目的節點且不去考量目的節點是否對訊息有興趣,但在真實社會並非只針對一個目的節點進行訊息散播,而是無法知道整個網路環境下有誰對要散播的訊息有興趣想接收,這將不會只有散播給單一的目的節點,若是濫發也會產生過多的成本,故本研究考量耐延遲網路環境下興趣訊息散播的方法,能夠散播給真正需要訊息的人並且減少傳播成本。
由於智慧型行動裝置普及與行動網路技術成熟,為更貼近真實世界的訊息散播情境,本文探討第三個研究主題為大眾在網路社群平台與其它人虛擬相遇的訊息散播方法。每個人在使用社群平台都會有各自不同的操作行為,依據使用者當下的心情、習慣及時間進行不同的操作,本研究認為若能從不同的行為模式歸納出一個訊息散播的模型,將有助於發現在真實世界下有效率的訊息散播方法。
綜觀各個階段的研究,本文最後探討整合實體與虛擬環境下訊息散播的方法,進一步提出在虛實網路下訊息散播模型,經由實體與虛擬不同的散播特徵找出較有效率的訊息散播模型。
Regardless of their generation, people value broadcasting messages to allow as many of them know as possible within a limited amount of time as a very important matter. Due to timeliness possessed by some messages, it would be too late to be informed only after those are expired, thus making finding an efficient message propagation method one of the popular research topics.
This paper investigates methods to propagate messages in virtual and physical environments in depth. The first research topics focuses on finding a model for nodes’ movements in a delay tolerant network environment. The frequency of physical contact between nodes would influence evaluating opportunities of message propagation. To evaluate whether a message propagation method is appropriate to use in the actual society or not, the simulation based on a real-world movement model as required is more suitable for estimating and predicting how long messages need to effectuate in the actual society.
The second research topic is that estimating message propagation methods must put whether the audience is interested at the message or not into consideration. When reflecting on past researches, we can tell most of them mainly focus on message propagation to a single target node without evaluating whether the node is interested at the message. However, in a real-world society, message propagation is not only directed towards one target node, but also all nodes which are likely to be interested at the message and willing to receive it in corresponding network environment without pre-existing knowledge. Obviously this will not only include that one single target node. Considering that flooding messages incur unnecessary costs, this research adapts a method of propagation messages with interests in a delay tolerant network environment, allowing messages to be dispersed to people who really need those messages and therefore reducing propagation costs.
As smart mobile devices become common and mobile network technology matures, this paper, for better aligning with the real-world message propagation scenario, investigates the third research topic which is the message propagation method in the case of the masses making virtual contacts with others on internet social platforms. Each person would operate differently when using social platforms according to his or her emotions, habits, and schedules. We believe that if we are able to conclude a generalized message propagation model based on different behavior pattern, it would be extremely helpful for finding an efficient message propagation method in the real world.
Based on the observations made in each stage of the research, this paper will focus on message propagation methods via an integrated physical and environment in the last part. A message propagation model in virtual and physical environments should be proposed as the next step which involves in utilizing different propagation characteristics of physical and environments to determine a more efficient message propagation model.
