“…Song et al [35] in 2012 studied the coding gains for applying XOR retransmissions at both source and relay nodes in the case with two sources and many destinations. Shrader et al [36] in 2011 focused on the proxy case, in which destinations are formed into multiple clusters and destinations can act as relays for other destinations in the same cluster. In the proxy case, the benefit of cooperative strategies for multicasting over wireless lossy links is explored, particularly in terms of the number of packets sent by source and relays.…”

The relay-assisted, network-coding (RANC) automatic repeat request (ARQ) protocols are ARQ protocols that leverage both opportunistic retransmission and network coding for wireless relay networks. This paper proposes two single-relay RANC ARQ protocols, the listen-and-supersede (LS) protocol and the hold-and-proceed (HP) protocol. LS offers a fundamental limit to any single-relay RANC ARQ protocol. HP is a simple yet efficient RANC ARQ protocol with near-zero overhead. Moreover, we analyze saturation throughput and segment delay for both LS and HP. Their performances are compared with a representative cooperative ARQ protocol, the opportunistically forwarding (OF) protocol. Through extensive analysis and simulation results, we show that HP has a performance close to LS and outperforms OF significantly.Index Terms-Cooperative ARQ, opportunistic retransmission, network coding, queueing model, wireless network.

“…However, in the literature, most of the works either focus on pure source-dominated multicast or focus on cooperative data exchange by assuming that each user initially holds a subset of packets. The only work that considers the hybrid architecture of source transmission and data exchange transmission is in [16]. Specifically, the source node is set to stop sending the packets once the destinations in each cluster can collectively reconstruct the original packets, followed by the cooperative data exchange within each cluster.…”

“…So far, only the work in [16] studies the hybrid source transmission and cooperative data exchange for wireless multicasting, and it stops the source sending exactly once the destination nodes within each cluster collectively hold the complete information. Although the scheme in [16] performs well in reducing the transmission delay, it is still possible that the cooperative data exchange by multiple clusters may consume more transmission cost/energy than source-dominated scheme. As discussed above, the cooperative data exchange needs to be conducted separately in each cluster, and thus the sum of their transmission costs may exceed the transmission cost with pure source transmission.…”

“…As discussed above, the cooperative data exchange needs to be conducted separately in each cluster, and thus the sum of their transmission costs may exceed the transmission cost with pure source transmission. In addition, the predefined clusters in [16] might not perform well, as the destination nodes in some clusters may collect the complete information more quickly than the destinations in other clusters, which may stop the source transmission too late for the other clusters.…”

We study multicasting over wireless lossy links. Instead of downloading all the data from the source node, we allow the destination nodes themselves to locally exchange the packets, as local communication within a cluster achieves higher packet reception probability with less transmission cost. However, when shall we stop the transmission from the source node? If the source stops too early, the destination nodes locally cannot reconstruct all the original packets, while if the source stops too late, the benefit of cooperative data exchange cannot be fully exploited. In this paper, we propose a network coded hybrid source and cooperative exchange scheme to determine when to stop the source sending and start the exchange process, so as to minimize the total transmission cost. For the case when the clusters are predefined, we derive the expected total transmission cost with our hybrid scheme. Our theoretical results show that under a special condition, the source node should keep sending the packets until all the destinations get the complete information. For the case when the clusters are not predefined, we propose a cluster division algorithm such that the destination nodes within each cluster can conduct data exchange locally with energy efficiency. Finally, simulation results demonstrate the effectiveness of the proposed scheme.
