Abstract
Mobile phones and personal digital assistants are becoming increasingly important in our daily life since they enable us to access a large variety of ubiquitous services. Mobile networks, formed by the connection of mobile devices following some relationships among mobile users, provide good platforms for mobile virus spread. Quick and efficient security patch dissemination strategy is necessary for the update of antivirus software so that it can detect mobile virus, especially the new virus under the wireless mobile network environment with limited bandwidth which is also large scale, decentralized, dynamically evolving, and of unknown network topology. In this paper, we propose an efficient semi autonomy-oriented computing (SAOC) based patch dissemination strategy to restrain the mobile virus. In this strategy, some entities are deployed in a mobile network to search for mobile devices according to some specific rules and with the assistance of a center. Through experiments involving both real-world networks and dynamically evolving networks, we demonstrate that the proposed strategy can effectively send security patches to as many mobile devices as possible at a considerable speed and lower cost in the mobile network. It is a reasonable, effective, and secure method to reduce the damages mobile viruses may cause.

Summary
The last decade has witnessed a surge of wireless mobile devices such as mobile phones, PocketPCs, netbooks, and tablet PCs. Through many experiments involving both synthetic and real-world networks, we find that the proposed SAOC-based strategy can quickly send security patches to as many phones as possible in the mobile network with limited bandwidth which is large-scale, decentralized, dynamically, and of unknown network topology. It can control the number of patches disseminated at each time step and make adjustment according to the network conditions. The network congestion and the waste of the network resources can be avoided because each phone receives the patch only once
