The distributed, heterogeneous and anonymous attribute of P2 P networks make the node information sharing facing security problems. In order to prevent malicious and false service of nodes, and improve the retrieval efficiency, the primary node selection algorithm based on trust mechanism is proposed in this paper. Firstly, the network topology based on virtual community is described, and the function of primary node is discussed. Secondly, the primary node is selected according to direct trust value and recommendation trust value of each node in the virtual community. Finally, resource retrieval algorithm is designed according to the selected trust primary node, and the algorithm is experimentally verified. In some certain extent, the results show that the method is able to reduce the fraud of primary node and improve the retrieval efficiency.

With the increasing number of cores in multiprocessor System-on-Chip (SoC), the design of an efficient communication fabric is essential to satisfy the bandwidth requirements of multiprocessor systems. Nowadays, scalable Network-on- Chips (NoC) are becoming the standard communication framework to replace bus-based networks. In this paper, we propose a deadlock-free XY-YX router for on-chip networks. In order to prevent deadlocks, we exploit additional physical channels in horizontal direction and optimize the priority of output channel allocation. Experimental results prove that the proposed deadlock-free router enhances the throughput of NoC.
