Improved Polar selective decoding and forwarding cooperation by Qichao SUN, Jianrong BAO, Chao LIU, Bin JIANG, Fang ZHU, Jianhai HE

“…An improved Polar selective decoding and forwarding (IPSDF) scheme based on cooperative threshold de-cision was proposed.Firstly,a new construction of Polar codes according to the fading channel state information (CSI) was proposed.Then,a relay with best CSI was selected from the candidate relay set as the best relay.In addition,the proposed Polar codes were introduced into the cooperative communication system,to get coding gain and reduce the complex of encoding and decoding.Simulation results show that the proposed Polar codes achieve about 0.3 dB gain at bit-error-rate (BER) of 10<sup>−3</sup>.And using a classic multi-relay cooperative model,the proposed scheme achieves about 0.8 dB and 1.3 dB gain at BER of 10<sup>−3</sup>,when compared with those the existing DF Polar+ and network Polar coded coopera-tion scheme.Therefore,the IPSDF scheme can be used to improve BER performance in a multi-relay cooperative system and it is quite suitable for heterogeneous network applications in cooperative communication.…”

Study on a cooperative MAC protocol with priority-based contention for wireless networks by LIU Yun, LIU Kai, ZENG Feng

“…A cooperative medium access control protocol with priority-based contention（PBC-CMAC） was presented for wireless networks.In the protocol,a source node preselected two optimal relays from its local relay information table,and set their priorities in cooperative request-to-send（CRTS） packet based on the relay efficiency,which reflects the de-gree of its saved transmission time.Through overhearing the handshakes between the source node and destination node,the two candidate relays can obtain instantaneous transmission rate among source node,destination node and themselves,and then contend to be the final relay without contention collisions according to their priorities and rate information.The proposed protocol can rapidly select the optimal relay to cooperatively transmit data packets under current channel qual-ity without contention collisions from all the potential relays,increase the successful probability of relay selection and cooperation efficiency,and then improve multiple access performance.Simulation results show that the proposed proto-col outperforms IEEE 802.11 request-to-send/clear-to-send（RTS/CTS） and CoopMAC protocols.…”

Recent advances and future challenges of four key resources cooperation in cognitive radio network by Xianzhong XIE, Ying LUO, Ke YAN, Jiujiu CHEN

“…Cognitive radio (CR) can improve spectrum utilization by spectrum sharing or cooperation between the primary user and secondary users.It is well known that energy,interference and relay are also three key resources in cognitive radio network (CRN).Energy cooperation or sharing between the primary user and secondary user will further promote energy efficiency.Energy harvesting from RF interference signal can turn bane (interference) into a boon (green energy).Secondary user relay data of the primary user can enhance QoS of the primary user,also get some opportunities for their own transmission.Thus,four resources cooperation (spectrum,energy,interference,relay) in CRN will improve simultaneously both spectrum efficiency and energy efficiency,and also increase throughput and QoS.The overviews for collaborative utilization problems of four key resources in CRN was given.Firstly,collaboration models of four key resources were analyzed.Then,recent research advances were summarized,including three kinds of resources collaborative utilization (both energy harvesting and relay transmission,both energy cooperation and energy harvesting) and four resources collaborative utilization (simultaneous relay transmission,energy harvesting and energy cooperation) in CRN.Further,some potential challenges of four key resources cooperation in CRN were discussed.Finally,some key future research directions was concluded.…”
