Computer Virus Propagation Model Based on Variable Propagation Rate

In this paper, two different propagation models based on different topologies of email network are proposed. By analyzing the means and the characters of email virus spreading, the function of email virus propagation is given, and the maximum time of email virus propagation before the anti-virus software is calculated. The...

Performance Enhancement of WLAN Using 802.11n and MIMO Technology

802.11n is IEEE wireless standards that significantly improve throughput and range of Wireless Local Area Networks WLAN compared with other 802.11 standards. It is expected to provide a throughput of over 100 Mbps, which is twice that of 802.11g. This difference is because it is designed to operate in both...

Affinity propagation for faster computing

Canadian computer scientists have developed a new algorithm named affinity propagation which can considerably speed up IT systems. One of the researchers said that affinity propagation works by considering all possible interpretations of the data at once. This new algorithm is based on pairing up pieces of data instead of...
