WhatsUp: news from, for, through everyone


WhatsUp (wup) is a new form of electronic news which is decentralized and personalized. No big brother company controls the news, and no central server makes it vulnerable to failures, censorship or attacks. wup does not rely on any explicit subscription scheme but leverages the interest expressed by the readers of the news to personalize its dissemination. Basically, wup users express their interests simply by giving opinions about the news they read. This opinion, in turn, impacts the news these users receive in the future. Underlying wup lies Beep, a biased epidemic dissemination protocol that delivers news to interested users in a fast manner and using little bandwith, despite jamming and churn. Beep is parameterized on the y on a per user, per news and per dissemination hop basis. This protocol has two key characteristics: orientation and amplication. Every user forwards the news of interest to a randomly selected set of users with a preference towards those that have similar interests (orientation). The notion of interest does not rely on any explicit social network or subscription scheme, but rather on an implicit and dynamic overlay capturing the commonalities between users with respect to they are interested in. The size of the set of users to which a news is forwarded depends on the interest of the news and its origin (amplication).
