ABSTRACT

An algorithm for constrained flooding based on negative selection is proposed due to improve delay of flooding and quality of operation when the network transmit the fault information. According to the network environment different demand between delay of flooding and quality of operation, cost function of flooding delay and operation losing are set, the optimizing objective function synthesize two factor is also set, and negative selection algorithm is used to compute the area of constrained flooding. The experimental result shows that this algorithm can improve the capability in network.
