Accommodating an increasing number of machine‐to‐machine (M2M) devices is one of the main issues faced by the cellular networks. In a typical M2M setup, several devices may try to connect to the network simultaneously. Long‐term evolution advanced (LTE‐A) networks use a random access procedure for this purpose, which is not sufficient to cater for a large number of devices. The conventional procedure is extended by allowing several devices to access the network with reduced collisions. Mathematical analysis and simulation results show that the proposed scheme increases the access probability as well as the number of successful transmissions.
