Advances in computer science prompt the creation of new economic models. One of them in urban life is Sharing Economy. This new economic model receives high attentions and has been applied to a wide range of fields in recent years. We argue that sharing economy, and its applications, may be taken as a way for researchers to understand human behavior, and thus this paper targets a growing issue on...
Message ordering is one of the essential problems in distributed systems and applications. In spite of the importance, most of publish/subscribe systems do not guarantee the ordering of messages and events because of its cost which may give an impact on the overall performance. When we suppose dynamic systems, such as peer-to-peer systems, the implementation of the message ordering would be pretty...
Due to the amount of anonymity afforded to users of the Tor infrastructure, Tor has become a useful tool for malicious users. With Tor, the users are able to compromise the non-repudiation principle of computer security. Also, the potentially hackers may launch attacks such as DDoS or identity theft behind Tor. For this reason, there are needed new systems and models to detect the intrusion in Tor...
In this paper, we discuss a peer-to-peer (P2P) model of a topic-based publish/subscribe (PS) system (P2PPS model) where each peer process (peer) can both subscribe and publish event messages with topics and there is no centralized coordinator. Each peer has to causally deliver event messages in which the peer is interested. In our previous studies, the TBC (topic-based causally delivery) protocol...
