Multi-Radio Cooperative ARQ in Wireless Cellular Networks: A MAC Layer Perspective

Free registration required

Executive Summary

Multi-Radio Cooperative Automatic Retransmission ReQuest (MCARQ) schemes are introduced in this paper within the context of hybrid networks which combine long-range and short-range communications. Since the number of wireless devices is incessantly increasing, it is frequently possible to establish a spontaneous cooperative cluster in the close proximity of any wireless device. These devices forming the cluster are connected to both a cellular-based network such as WiMAX, 3G, or LTE and a short-range network based on technologies such as WLAN, Zigbee, Bluetooth, or UWB, among other possibilities.
