Design and Performance Evaluation of Cooperative Retransmission Scheme for Reliable Multicast Services in Cellular Controlled P2P Networks

Abstract

Reliable multicast applications such as software distribution, data distribution and replication and mailing list delivery, etc.[1] are getting more and more interests from network and service providers. The conventional error/loss recovery schemes are not efficient when they are applied to multicast scenarios in wireless networks. The reason lies in the unreliable wireless channel, the limited wireless bandwidth and resource, the battery powered wireless devices, and others. To have an effective error/loss recovery scheme for reliable multicast in wireless networks, we advocate a new communication architecture. It is referred to as cellular controlled peer-topeer network [2], where the mobile devices communicate directly with each other to perform cooperative retransmissions using their short-range communication capabilities in addition to their cellular links. Based on the cooperative architecture a novel retransmission scheme is proposed exploiting the shortrange retransmission in this paper. The state of the art, the non-cooperative error recovery schemes (e.g., ARQ, Layered FEC and Integrated FEC II) and the proposed scheme are compared with each other in terms of energy consumption to show the benefit of the newly introduced scheme.

Reliable Machine-to-Machine Multicast Services with Multi-Radio Cooperative Retransmissions

“…Cooperative schemes, as generically depicted in Figure 1, have proven to outperform non-cooperative approaches in terms of energy consumption per device in several practical scenarios [11,12,13,14]. As an example, an efficient and scalable solution based on a cooperative retransmission scheme was proposed in [12].…”

“…As an example, an efficient and scalable solution based on a cooperative retransmission scheme was proposed in [12]. In this solution, direct Device-to-Device (D2D) communication is established between nearby devices to form cooperative clusters, referred to as wireless grids.…”

“…In [12], It is assumed that all devices are simultaneously connected to a cellular access point (or base station) through a long-range link and can establish a short-range distributed area network. Therefore, both centralized (long-range) and distributed (short-range) topologies can cooperate to enhance the performance of the system [13].…”

“…Transmission errors over the longrange link can be recovered by local retransmissions performed by the surrounding devices over the shortrange link. In the strategy proposed in [12], a Time Division Duplex (TDD) system was considered, where the base station dynamically reserves cooperation slots in the uplink subframe to carry local retransmissions. The scheme is proven to outperform other alternatives [12].…”

The scheme is proven to outperform other alternatives [12]. However, it does not consider the cooperation strategy over an additional radio technology.…”
