“…In summary, the proposed ISHDAF scheme obtains much more outage probability performance gain by the direct link retransmission rather than the relay forwarding, when compared with the IHDAF one in [8]. In other words, the diversity gain in the ISHDAF scheme is better than that of the IHDAF one, because the overall channel transmission effect (retransmission and then cooperative relay communication) in the former is superior to that (just cooperative relay communication) in the latter.…”

“…However, all gains were obtained under equal power allocation of the source and relay nodes for the low systematic complexity, which caused the deficiency of only few performance improvements. To improve the 2 Wireless Communications and Mobile Computing spectral efficiency of the system, there was also a signal-tonoise ratio (SNR) based incremental hybrid decode-amplify forward (IHDAF) protocol proposed in [8]. Furthermore, the SNR thresholds, the power allocation schemes, and the relay locations were studied to optimize the outage probability and BER performance.…”

An incremental selection hybrid decode-amplify forward (ISHDAF) scheme for the two-hop single relay systems and a relay selection strategy based on the hybrid decode-amplify-and-forward (HDAF) scheme for the multirelay systems are proposed along with an optimized power allocation for the Internet of Thing (IoT). Given total power as the constraint and outage probability as an objective function, the proposed scheme possesses good power efficiency better than the equal power allocation. By the ISHDAF scheme and HDAF relay selection strategy, an optimized power allocation for both the source and relay nodes is obtained, as well as an effective reduction of outage probability. In addition, the optimal relay location for maximizing the gain of the proposed algorithm is also investigated and designed. Simulation results show that, in both single relay and multirelay selection systems, some outage probability gains by the proposed scheme can be obtained. In the comparison of the optimized power allocation scheme with the equal power allocation one, nearly 0.1695 gains are obtained in the ISHDAF single relay network at a total power of 2 dB, and about 0.083 gains are obtained in the HDAF relay selection system with 2 relays at a total power of 2 dB.

“…The important and interesting question this chapter tries to answer is what is the maximum aggregate throughput of a multi-radio multi-channel network when the cooperative transmission is available? Current studies on cooperative communications in multi-hop wireless network generally assume that the network nodes are equipped with only a single antenna [12][13][14][15][16][17][18][19][20], and it is unclear what capacity and performance gain can be achieved if nodes are equipped with multiple antennas. Despite the large potential beneit, it is highly non-trivial to make both CC and MRMC techniques to work seamlessly together.…”

There are many recent interests on cooperative communication (CC) in wireless networks. Despite the large capacity gain of CC in small wireless networks, CC can result in severe interference in large networks and even degraded throughput. The aim of this chapter is to concurrently exploit multi-radio and multi-channel (MRMC) and CC technique to combat co-channel interference and improve the performance of multi-hop wireless network. Our proposed solution concurrently considers cooperative routing, channel assignment, and relay selection and takes advantage of both MRMC technique and spatial diversity to improve the throughput. We propose two important metrics, contention-aware channel utilization routing metric (CACU) to capture the interference cost from both direct and cooperative transmission, and traic aware channel condition metric (TACC) to evaluate the channel load condition. Based on these metrics, we propose three algorithms for interference-aware cooperative routing, local channel adjustment, and local path and relay adaptation, respectively, to ensure high-performance communications in dynamic wireless networks. Our algorithms are fully distributed and can efectively mitigate co-channel interference and achieve cooperative diversity gain. To our best knowledge, this is the irst distributed solution that supports CC in MRMC networks. Our performance studies demonstrate that our algorithms can signiicantly increase the aggregate throughput.

“…Otherwise, the destination sends a request to the relay asking the relay to retransmit the signal after recoding. Some works have been proposed for conditional schemes [9][10][11][12][13][14][15][16][17][18][19][20][21][22]. Closed-form expressions for error probability of both the incrementalselective DF relaying scheme and the incremental DF relaying scheme are derived in Rayleigh fading scenarios [9].…”

Int J Electron Commun (AEÜ) (2016), http://dx.: Conditional decode-and-forward scheme Nakagami-m fading channel Outage probability Average symbol error rate Multiple phase shift keying Multiple quadrature amplitude modulation a b s t r a c tIn this work, a dual-hop cooperative system with conditional decode-and-forward (DF) scheme over Nakagami-m fading channels is studied. The considered system consists of a Source-Destination (S-D) pair and a relay node (R). R adopts conditional DF relaying scheme to decide whether to aid S-D pair's information transmission or not, under which R employs the signal-to-noise ratio of S-D link as an indication of the need of the cooperation aid. The outage performance has been investigated over Nakagami-m fading channels for integer values of m, as well as the symbol error performance of multiple phase shift keying and multiple quadrature amplitude modulations. The closed-form analytical expressions for outage probability and average symbol error rate have been derived and verified by Monte-Carlo simulations. Simulation and numerical results match very well with each other, which indicates that our proposed analytical models can well predict the outage and symbol error performance of the target conditional DF relaying schemes over Nakagami-m fading channels.
