We propose a remapping algorithm to tolerate the failures of Processing Elements (PEs) on Multiprocessor System-on-Chip. A new graph modeling is proposed to precisely define the increase of communication cost among PEs after remapping. Our method can be used not only to repair faults but also to improve the communication cost of given initial mapping results. Experimental results show that under multiple...
We design the optimal jamming attack strategy for a cognitive radio network in the presence of path-loss decaying signal models. We consider a cognitive radio network with K participating cognitive radios and one fusion center in the presence of one primary user and one jammer in the operating region. We assume that the network is not aware of the presence of the jammer and hence employs the optimal...
