An automatic co-stimulation algorithm for LAN artificial immune systems

Co-stimulations are very important in LAN AISs, but there are few automatic co-stimulation algorithms or approaches at present, and almost all of co-stimulations are implemented by network-administrators. We try to find an automatic co-stimulation algorithm to replace the administrators in LAN AISs. Detectors employed to detect abnormal packets are called NS-detectors. Detectors employed to detect normal packets are called PS-detectors. Each NS-detector can detect a different kind of potential abnormal packets. Each PS-detector can describe a different kind of normal network behaviors. The NS-detector generation algorithm and the PS-detector generation algorithm are presented first. Based on them, an automatic co-stimulation algorithm for LAN AISs is described in detail. Co-stimulations in LAN AISs can be implemented automatically with the algorithm. The administrators can still implement co-stimulations, but their co-stimulations are not important. The feasibility of the algorithm is illustrated with our experiments in laboratory. Our further work is to illustrate more the feasibility of the algorithm in the Internet environment.
