“…Simulation results reported in [9] show that DQCOOP outperforms any 802.11-based MAC protocol in terms of average packet transmission delay when cooperation is requested and, what is most important, its operation is almost independent of the number of relays and behaves as a perfect TDMA scheduler with some overhead. However, the work presented in [9] was only based on computer simulations. Therefore, there is a lack of an analytical model that allows evaluating the performance of the protocol.…”

“…However, the knowledge of the number of possible helpers for a failed transmission is hardly predictable, and thus a protocol whose operation is independent of the number of contending station would be desirable. This was the main motivation for the design of the Distributed Queuing MAC Protocol for Cooperative Networks (DQCOOP) presented in [9]. DQCOOP is based on the near-optimum DQCA MAC protocol designed for the uplink channel of centralized WLANs [10], which in its turn, is based on DQRAP [11].…”

Abstract-In this paper we analyze the performance of a distributed queuing medium access control (MAC) protocol designed to execute cooperative ARQ (C-ARQ) schemes at the MAC layer. Due to the broadcast nature of the wireless channel, a user that receives a data packet with unrecoverable errors can request retransmission from any of the other users in the transmission range of the transmitter that overheard the original transmission. These users can act as spontaneous relays and provide the communication with cooperative diversity gains. Upon retransmission request, the relays have to contend for the access to the channel. The DQCOOP protocol has been proposed in the literature as a high-performance MAC protocol for this kind of scenario. In this paper we theoretically evaluate its performance. The analytical results are supported by computerbased simulation that show the accuracy of the analysis.

“…Alongside more mature Physical layer [6] [7] and MAC layer [8] [9] mechanisms to support cooperative communication, research interest has grown regarding cooperative communication at the Network layer. Authors in [10] propose a model for cooperative communication using a decode-andforward approach, where a node which plays a role of a relay tries to decode an entire message and forwards it to the next hop.…”

Abstract-Frequent link breaks (due to node mobility) and quick exhaustion of energy (due to limited battery volume) are two major problems impacting on the flexibility in Mobile Ad hoc Networks (MANETs). Cooperative communication in MANETs has become an appealing topic, as it can improve system capacity and energy efficiency. In spite of such advantages of cooperative communication, some issues still remain such as the lack of a systematically designed cooperative routing scheme (including route discovery, route reply, route enhancement and cooperative data forwarding), facilitation of cooperative communication in mobility resistance, and route selection (jointly considering energy consumption, energy harvesting ability and link break probability). Driven by the above concerns, we propose a novel Constructive Relay based CooPerative Routing (CRCPR) protocol in this article. Using topological information stored and maintained in a COoPerative (COP) Table and Relay Table, CRCPR enhances resilience to mitigate the mobility issue by self-managing to construct adequate relays for data forwarding. Furthermore, assuming nodes are mostly battery-operated, CR-CPR proposes a new route selection mechanism which takes into account energy consumption, energy harvesting and link break probability, to determine an appropriate route across a network. Simulation results show the robustness of CRCPR against node mobility, further with improvement for up to 60% network throughput and 40% prolonged network lifetime.
