Virtual Network Topology is used to carry IP traffic over Wavelength-division multiplexing optical network. To use network resources in the most optimal way, there is a need for an algorithm, which will dynamically re-share resources among all devices in the particular network segment, based on links utilization between routers. Attractor selection mechanism could be used to dynamically control such Virtual Network Topology. The advantage of this algorithm is that it can adopt to very rapid, unknown and unpredictable changes in traffic flows. This mechanism was adopted from biology - gene regulatory networks in cells use it to adopt to unknown changes in the environment. The dynamical system modeling the gene regulatory network is considered. The relations between genes are described by the regulatory matrix W with the entries from the set {−1, 0, 1} meaning inhibition, no relation and activation respectively. The structure of the attracting set in some specific case is studied. It is remarkable that the attracting set contains a focus-type critical point.","PeriodicalId":229246,"journal":{"name":"2016 Advances in Wireless and Optical Communications (RTUWO)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130079931","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 measured signal was profiled and compared with the prediction of widely used empirical path loss models over the terrain. The results show that all models' prediction errors follow the terrain elevation. The prediction errors were normalized to fit into the Gaussian normal distribution (GND). A close agreement between the measured and predicted distributions show that the GND is an excellent approximation for the prediction error for both UHF and VHF data with a slight deviation observed from the two curves due to terrain variation.","PeriodicalId":229246,"journal":{"name":"2016 Advances in Wireless and Optical Communications (RTUWO)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127684757","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}

Voice-over-Wi-Fi (VoWiFi) is an alternative data-driven IP-based dialing service for indoor users with poor cellular coverage. The recent rollout of iPhone6+ running IOS8 with novel Wi-Fi dialing feature spurred several operators around the world to invest on VoWiFi as a complementary service. As such, when cellular coverage is poor, calls are placed/switched over to wireless local area network (WLAN) in a transparent manner to users. Given the heterogeneity of the setup, a high uncertainity arises regarding whether the switching (handoff) task remains unnoticed to the users or not. There is also the issue of interference over WLAN as well as congestion in internet core that is often added to the obscurities. Inspired by these facts, this paper investigates the suitability of VoWiFi in satisfying the voice service quality requirements for home and small network users. Three different architectures are investigated based on handoff, load-balancing and repeater. The voice reception quality in terms of jitter, delay and packet loss is monitored for each architecture. It is observed that delay, jitter and packet loss are improved in repeater-based scenario whereas call drop is experienced in both handoff and load balancing scenarios.","PeriodicalId":229246,"journal":{"name":"2016 Advances in Wireless and Optical Communications (RTUWO)","volume":"os-29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127774333","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}

Considering uniform quantization for both digital-to-analog converter (DAC) and analog-to-digital converter (ADC), analytical expression for signal-to-distortion-quantization ratio has been evaluated. A lower bound on required bit resolution for DAC/ADC, as a function of clipping ratio has also been determined for a target bit-error-rate (BER). Gain in modulation power at the output of the DAC under severe clipping conditions has been analytically evaluated. Furthermore, an iterative method for clipping mitigation is presented, which can be employed to relax the bit resolution required by the DAC, and further, to mitigate the clipping distortions.","PeriodicalId":229246,"journal":{"name":"2016 Advances in Wireless and Optical Communications (RTUWO)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115823279","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}
