Wireless ad hoc networks use mobile devices to deliver services supported by high-speed network connections and high-speed data transmissions in real time. These devices (network nodes) typically act as the network infrastructure to forward data to other nodes from a source to the destination. However, several constraints (e.g., processor, energy consumption, and bandwidth) affect the overall network performance. Cooperation strategies have been considered as a solution to such network limitations and constraints. Recent studies have presented cooperation mechanisms as a solution to unstable network infrastructures where mobile nodes cooperate with each other, forwarding data and performing all the networking functionalities. This paper presents a comprehensive review of the state of the art on cooperation strategies and algorithms for mobile ad hoc networks and delay-tolerant networks. These challenged networks frequently comprise situations where traditional Internet protocols fail to effectively provide desired or expected communication. This paper focuses on cooperation incentive-based approaches for network architectures that support mobile devices and are challenged by mobility constraints such as battery and storage capacity, broadcast constraints, interferences, disconnections, noises, limited bandwidths, and network delays. The surveyed approaches' merits and weaknesses are discussed, and open issues are identified. Finally, conclusions are detailed.

“…However, to achieve the expected gains, the antennas must be properly spaced, which may be impractical in small-sized devices. Cooperative communication [3][4][5][6][7][8][9][10] emerged as an alternative to the use of multiple antennas. Probably, the two most known cooperative protocols are the amplify-and-forward (AF) and the decode-and-forward (DF) [3].…”

“…Later, the association of error correcting codes with AF and DF protocols showed to considerably increase the performance [6][7][8][9][10][11], giving rise to what is called coded cooperation. Convolutional codes [6,8], turbo codes [7,8] and LDPC codes [9][10][11] are some important coding techniques that were associated with the relay channel.…”

In this paper, we present a novel hybrid automatic repeat request (HARQ) scheme for cooperative communication systems, called cooperative partial retransmission (CPR). The method is based on the retransmission of only a fraction of the original code word by the cooperating nodes. Based on the outage analysis, we derive the theoretical throughput expressions that are compared to numerical simulations using LDPC codes, showing that CPR outperforms regular cooperative HARQ techniques. Additionally, we show that the CPR throughput, even using a single relay, may be considerably larger than the throughput of a regular cooperative HARQ scheme using multiple relays. Finally, the energy consumption analysis of the schemes shows that CPR consumes less energy than regular cooperative HARQ, mainly due to the shorter retransmissions.

In this paper, a single-hop single-relay system with a direct link between the source and the destination is considered when the relay operates in the half-duplex mode. Motivated by the concept of signal space diversity, this paper introduces signal space cooperation, in which cooperation between the source and the relay is achieved using a novel constellation design approach. In this approach, the original constellation is expanded so that each member of the new constellation inherits its components from at least two members of the original constellation. The expanded constellation enables the relay to extract the required information in order to cooperate in the relay phase, and it helps the destination to effectively combine received signals during the broadcast phase and the relay phase. The analytical study of the proposed scheme leads to the development of two design criteria for the constellation expansion approach. The proposed design criteria aim at maximizing the relay role in the cooperative scheme by increasing the performance of the source-relay link. In this way, the source and the relay can effectively cooperate in order to maximize the overall performance of the system. The signal space cooperative scheme can be used for any constellation size without incurring significant complexity overhead to the system. Numerical results depict superior performance in comparison with other cooperative schemes such as the adaptive decode and forward and the distributed turbo code schemes.
