Simulation result of different friends number. A trust network based on community relationships plays an important role in FRep performance. Through simulation experiments, we analyzed the influence of network connectivity, that is, the number of online friends of each node on FRep performance. The experimental environment is still the collusion attack scenario. The collusion nodes account for 10% of the total number of nodes, and the number of friends is set as 14, 10, 6 and 2, respectively
