This paper proposes a new approach, Cooperator Resource Allocation Algorithm (CoopeRA), to improve the radio resources allocation scheme and reduce the impact of congestion in LTE Heterogeneous network (HetNets) and 5G networks by using Device-to-Device (D2D) communications and by borrowing some adjacent Macro-cell resources from the neighboring nodes that are belonging to the same WLAN network but not to same Macro-cell. Our solution is based on cluster construction and D2D transmissions in Local Area Networks (LAN) to relay the traffic of users belonging to congested LTE cells. Our new algorithm increases the number of new calls in the congested Macro-cell, even if the resources are limited. The simulation validates this study when the results shows the performance of our mechanism.
