In reality, many companies need a reliable and sustainable operation of the system, whether these systems are upgraded, maintenance, reconfiguration, or when an attack can last for more than provide responses to customer requests. Such a system is defined as the Persistence Computing System (PCS). PCS can be connected to the component or application by

As a new computational mode, P2P (peer-to-peer) network modifies the traditional C/S mode and is used more and more widely. Nodes can join in and quit network at any time and share resources voluntarily.But it causes that there are many free-rider and non-cooperative nodes. Tragedy of Common is very common in the network, and there

Unstructured P2P internet source searching algorithms have been a hot topic inthe P2P network studies. Nowadays lots of people devoted themselves to it, but thereare still some aspects that have to be improved, such as response time, networkoverlay and efficiency. Present algorithm uses blind forwarding which results in lowefficiency in source searching. Although some people
