The RBFN is used to exploit the channel correlation in the frequency domain. In this paper, we provide the compensation of laser phase noise (LPN) and nonlinear phase noise in 4-QAM coherent optical orthogonal frequency division multiplexing (CO-OFDM) system. Simulation results show that the proposed RBFN algorithm efficiently estimates the LPN and trajectory matches with the actual LPN. The RBF network also reduces the computational complexity and the RBF subnetworks to a great extent compared to $K$-means based RBFNN-NLE technique. With RBFN-PE algorithm, the optimum launch power (LP) increases to 1 dBm and at this LP, Q-factor improves by 2.6 dB. Furthermore, simulation results show that at an FEC limit (Q = 8 dB), the transmission reach increases by 4 spans with the RBFN-PE algorithm. Thus, we show that the system performance improves by increase in optimum LP and transmission reach with the proposed RBFN-PE.","PeriodicalId":116005,"journal":{"name":"2018 Fifteenth International Conference on Wireless and Optical Communications Networks (WOCN)","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125006719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Restricted Access Window (RAW)-based channel access mechanism of 802.11ah reduces collisions and improves scalability. However, the RAW mechanism creates congestion in the network having event-driven traffic generated randomly. This paper proposes a Quality of Service (QoS)-aware priority grouping and RAW scheduling algorithm for the 802.11ah-based network. The proposed protocol reduces collisions and ensures required bandwidth for rare but critical event-driven stations. Performance evaluation of the proposed scheme shows significant improvement over 802.11ah-based MAC protocol.","PeriodicalId":116005,"journal":{"name":"2018 Fifteenth International Conference on Wireless and Optical Communications Networks (WOCN)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128748782","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To create an authentic and anonymous data sharing, IDentity based Ring Signature (ID-RS) is one of the promising technique between the groups. Ring signature scheme permits the manager or data owner to authenticate into the system in anonymous manner. In conventional Public Key Infrastructure (PKI) data sharing scheme contains certificate authentication process, which is a bottleneck because of its high cost. To avoid this problem, we proposed Cost Optimized Identity based Ring Signature with forward secrecy (COIRS) scheme. This scheme helps to remove the traditional certificate verification process. Only once the user needs to be verified by the manager giving his public details, then the cost and time required for this process is comparatively less than traditional public key infrastructure. If the secret key holder has been compromised, all early generated signatures remains valid (Forward Secrecy). This paper discuss about how to optimize the time and cost when sharing the files to the cloud. In general better efficiency and secrecy can be provided for group sharing by applying above approaches.","PeriodicalId":116005,"journal":{"name":"2018 Fifteenth International Conference on Wireless and Optical Communications Networks (WOCN)","volume":"60 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124318010","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Characteristic impedance is first calculated at region of interest considering both Faraday inductance and kinetic inductance, and also assuming presence of either symmetric or antisymmetric mode due to electron oscillation. Formation of double-sided surface plasmon is also evident due to coupling between two single-sided SP waves at some particular separation distance between the metal plates.

The UWB MIMO antenna consists of two printed planar identical monopoles PA and PB respectively and a novel modified Minkowski complementary fractal structure is introduced in the ground plane for reinforcing the isolation of the MIMO system. Notch bands encompassing 3.3-3.8 GHz Wi-MAX, 3.7-4.2 GHz C-Band, 5.15-5.85 GHz WLAN are acquired by etching a rectangular slot on the common ground structure and etching rotated C-shaped slots on the planar monopoles respectively. The antenna's Ultra wide bandwidth ranges from 3.16 GHz to 12 GHz (VSWR $leq 2)$. The radiator and ground plane of the antenna are etched with an overall size of 26.75 mm $times$ 37.96 mm. The agreement between the various simulation results advocates that the intended antenna can be a worthy candidate for various UWB communication systems. All the simulated results depict that the proposed UWB MIMO antenna is an exceptional candidate for portable UWB as well as UWB MIMO systems.","PeriodicalId":116005,"journal":{"name":"2018 Fifteenth International Conference on Wireless and Optical Communications Networks (WOCN)","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115678051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to extend the limited coverage of the mmW small cells, network-assisted relay involving device-to-device (D2D) communication is one of the key promising techniques. However, in the crowded area, which is a typical deployment scenario of 5G systems, conventional relay-path selection schemes are not applicable due to intense collisions of D2D synchronization signals (SSs). In addition, when selecting the relay-path, conventional schemes do not consider the backhaul quality to connect the Internet, which is necessary to guarantee end-to-end throughput for some Guaranteed Bit Rate (GBR) type services like conversational video. To solve these problems, the proposed scheme reduces the number of candidate relay users transmitting D2D SSs by applying several constraints such as requested throughput to exclude the relay users unable to satisfy the constraint. As an example of simulation results, it is observed that the proposed scheme reduces the number of D2D SSs by 96%, comparing with conventional schemes, in the case that a requested throughput from a remote user is set to 13.6 Mbps.","PeriodicalId":116005,"journal":{"name":"2018 Fifteenth International Conference on Wireless and Optical Communications Networks (WOCN)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124888454","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Candidates having confidence value higher than the threshold are extracted as final OT and OW.
