全球無線通訊網路的成長、掌上型裝置的激增與個人生活中要求隨時與人保持聯繫的需求，使得行動通訊快速地進入日常生活中。利用手機或PDA等無線行動裝置，每一個點都可以獨立的進行彼此的溝通，此環境與P2P網路雷同，利用手機所連結成的網路，形成的商業行為是一種新的商業管道，而集體購物經常發生在日常生活中，同一地區的人或親朋好友針對共同需求，一起購買相同的商品，以增加議價力量並達到降低售價的目的。
本研究提出在行動環境下之集體購物的系統架構，探討各階段消費者可能遇到的問題並提出輔助方法，讓這個環境內的行動裝置使用者更快速地找尋適合的集購資訊，使消費者擁有更多的購物資訊與制定較佳的購物決策。藉由Sensor Network結合MP2P網路的概念，快速的將欲散佈之集購訊息傳遞至賣場內各處，經由反覆實驗的觀察商場中的集購資訊散播率的變化，可以得知在某固定的商場中在哪些狀況之下可以有較佳的集購資訊散播率。

As the global wireless network becoming mature, the growing number of mobile devices, and the personal need of keeping in touch with others daily, mobile communication is becoming a necessity of life. Using mobile devices, such as cell phones or PDAs, everyone could communicate with each other independently; and this communication environment is similar with P2P network. Utilizing the connection network of cell phones is becoming a brand new business channel. Since group-buying is part of our daily life, people live in the same area could buy products or services together based on mutual needs, and this could enhance the bargaining power of customers and lower the purchase price.
This research proposes a group-buying system architecture under mobile environment, and discusses the problems that customers might encounter in every stage of the buying process. Mobile device users under the environment could exchange information with each other and this could help customers search group-buying information efficiently. Sensor Network combines with MP2P Network accelerates the spread of group-buying information in a marketplace, and helps the originator and other buyers to negotiate with the supplier.
Based on the observation of the variation of the group-buying information distribution in the experiment, we summarize under what situation a better information distribution would take place in a specific marketplace.
