N2 - This letter investigates the routing and traffic allocation strategies of the proximity radio access network (P-RAN), and provides a system model of the multi-hop and multi-connection (MHMC) network, aiming at reducing the end-to-end latency. Considering different resource scheduling mechanisms, we calculate the transmission probability of the relay nodes, and derive a closed-form expression of the end-to-end (E2E) data rate to reduce the latency of the network under the condition of signal's transmission guarantees. The relationships of E2E latency with networking parameters such as hops, connections of sub nodes, traffic allocation, priorities of relay signals and etc. have been analyzed under different user densities. Based on the theoretical analysis and simulation results, we present effective routing and update algorithms for the MHMC network, which is beneficial to low-latency device-to device (D2D) communications.
