Abstract
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, Bluetooh, or UWB, among other possibilities. The main
idea behind the proposed MC-ARQ scheme is that, upon transmission error
through the cellular interface, retransmission can be requested to the wireless grid
surrounding the destination device using the short-range interface instead of the
primary cellular link. Therefore, besides the cooperative diversity attained with CARQ
schemes, the traffic load in the cellular interface is reduced benefiting thus a
high number of users and reducing both energy consumption and interference.
The Persistent Relay Carrier Sensing Medium Access (PRCSMA) protocol is
presented as an example of solution for the MAC layer in this emerging new topic.
