Power consumption in associated active devices of the power amplifier (PA) increases with large PAPR and reduction of OOB is very important for the improvement of spectrum efficiency. In this paper, a DFT (discrete Fourier transform) - Spread WR-OFDM (windowing and restructuring orthogonal frequency division multiplexing) communication system is proposed in consideration of developing reasonably acceptable future generation mobile and wireless system based on the significant reduction of both peak-to-average power ratio (PAPR) and out-of-band (OOB) power spectrum components. In our proposed system, Tukey (tapered cosine) time-domain windowing and localized subcarrier mapping have been implemented. In AWGN and multipath Rayleigh fading channels, the system performances are compared with the WR (window and restructuring) - OFDM and conventional CP (cyclic prefix) - OFDM system. Numerical results show that up to 3 dB more PAPR reduction as compared to the WR-OFDM system and out-of-band attenuation of 110 dB can be achieved at the window length of 62.","PeriodicalId":417962,"journal":{"name":"2018 International Conference on Information and Communication Technology Convergence (ICTC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130025429","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}

Firstly, in view of the properties of THz communications, notably the sensitivities to the frequency and distance on the communication path, we employ Brownian motion to describe the mobility of nanomachine and build a time-variant channel model. Then, based on the channel model and energy resource of nanomachine, we develop a stochastic optimization to maximize the channel capacity. By virtue of the Lyapunov optimization theory, the problem of stochastic optimization is converted into a series of non-convex problems for the timeslots. The non-convex problem for each timeslot is further solved via the continuity relaxation and successive approximation theories. Moreover, we obtain a dynamic capacity sub-optimal resource allocation (CoRA) algorithm to accommodate the network only according to the current energy resource information and channel state information. Simulation results validate the theoretical analysis of our scheme.","PeriodicalId":417962,"journal":{"name":"2018 International Conference on Information and Communication Technology Convergence (ICTC)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128956587","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}

Although DNSSEC is an effective countermeasure to DNS cache poisoning attack, it still has low deployment rate in the Internet due to the significant workload increase on recursive DNS servers. Moreover, current DNSSEC operation does not cover end clients and the recursive DNS server separation has not been considered so that end users do not intend to use free and powerful public recursive DNS servers due to security concerns. In this paper, we propose a client based DNSSEC validation mechanism with recursive DNS server separation based on query types. DNSSEC related record types such as RRSIG, DNSKEY, DS, etc. will be forwarded to a trusted internal recursive DNS server while normal record types such as A, AAAA, MX, etc. will be forwarded to public recursive DNS server, and eventually, DNSSEC validation will be performed on end clients. Consequently, not only end clients can obtain the benefit of DNSSEC but also the workload increase of internal recursive DNS servers can be mitigated. We implemented a prototype system and evaluated the features on a local experimental network. Based on the results, we confirmed that the prototype system worked effectively and it is possible to prevent end clients from DNS cache poisoning attacks by the proposed mechanism.","PeriodicalId":417962,"journal":{"name":"2018 International Conference on Information and Communication Technology Convergence (ICTC)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129089446","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 backup network is designed to protect the primary network from the random multiple link failures with the probability of link failure. In a conventional approach, the routing in the primary network is not considered to be variable to minimize the total capacity in the backup network. Considering the primary routing as a variable to decide the backup network can reduce the total capacity in the backup network compared to that of the conventional approach. In the proposed approach, both routings in the primary and backup networks are considered as decision variables. Robust optimization is employed in our optimization problem to provide the probabilistic survivability guarantees for different link capacities in the primary network. Numerical results show that the proposed approach achieves lower total capacity in the backup network than that of the conventional approach.","PeriodicalId":417962,"journal":{"name":"2018 International Conference on Information and Communication Technology Convergence (ICTC)","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121445397","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}
