Abstract:	近年來隨著行動裝置及行動網路的普及，使得社群網路及各種社交聊天應用已融入使用者生活之中，但在許多場合如集會遊行、陳情抗議、大型室內外活動，因人潮聚集，使得行動無線網路訊號壅塞，致訊息無法正常傳遞。而隨著WiFi Direct及Bluetooth 4.0等無線技術的普及，行動裝置間的連線有了更多的選擇。本論文研究中，參考WaterChat的概念，重新設計一個可彈性適用於四種聊天情境地系統架構，搭配兩種私人聊天室的邀請模式，利用控制閥值以及監測節點連線及同步，減少Flooding造成的效率低落。實作一個基於隨機性社交網路且適用多聊天情境的社交聊天應用並加入了異地同步的機制，使得訊息傳遞範圍不再囿限於現實的地理限制，並在最後探討訊息加密的可能，提出並實作一新穎且功能完備的多群組行動聊天情境應用。 With the popularization of mobile devices and mobile networks, social networks and various social chat applications have played an important role in users’ daily life. However, in several large-scale events like protests or indoor/outdoor activities with large amount of people, due to mobile wireless network signal congestion, messages cannot be transmitted normally. Nowadays, new wireless technologies such as Wi-Fi Direct and Bluetooth 4.0 has provided more connection choices between mobile devices. First, we redesigned a system architecture based on the concept of WaterChat which is flexible and suitable for four different chat scenarios. Users can choose one of two invitation modes depending on their privacy requirements. Secondly, to solve flooding in opportunistic mobile network, we present threshold and connection control to improve the efficiency in our system. We also present an off-site synchronization, so the message transmission scope is no longer limited to the physical geographical restrictions. In the end, we will some discuss security issue and how to encrypt messages in four chat scenarios. To sum up, we design and implement a novel and full-featured WaterChat App based on intermittent-connected P2P Message flooding Mechanism.
