Based on Variable-gain Amplify-and-Forward (VAF) relaying scheme, the lower bound on Outage Probability (OP) of the mobile-relay-based Mobile-To-Mobile (M2M) networks over N-Nakagami fading channels is investigated in this paper. By the method of the harmonic mean of positive random variables, the exact closed form expression of the lower bound on OP is derived. Then the OP performance under different conditions is evaluated through numerical simulations. The numerical simulation results coincide with the theoretical results well, and the accuracy of the analytical results is verified.
