A comparative analysis has been made by replacing the conventional quarter wavelength transmission lines by stub loaded transmission lines. The proposed model has been designed on RT Duroid /5880 substrate and simulated using AWR Design Environment. Subsequent harmonics in the conventional rat race coupler are suppressed by reducing the electrical length less than 450. Simulation results of the designed coupler agrees well with the theoretical design.","PeriodicalId":234041,"journal":{"name":"2016 Thirteenth International Conference on Wireless and Optical Communications Networks (WOCN)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131486515","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}

This decomposition is necessary because practical limitations in radio implementation prevent the relay from simultaneously transmitting and receiving on the same channel. K relays in RCD require K+1 channels which shows that as the number of relays increases the number of required channels increases linearly. This increase in channels gives fundamental drawback in all cooperative diversity networks. So if this problem is not addressed the cooperative diversity networks will lose attractiveness for high data rate, high efficiency communications. In this paper this problem is addressed tried to find a solution. The performance of the best-relay selection scheme will be examined in which only the “best” relay takes part in relaying, therefore only two channels take part in transmission regardless of the number of relays. The relay node that gives the highest signal-to-noise ratio (SNR) at the destination node is considered to be the best relay. A general mathematic probability model is presented and examined the performance of best-relay selection using amplify and forward (AF) scheme.","PeriodicalId":234041,"journal":{"name":"2016 Thirteenth International Conference on Wireless and Optical Communications Networks (WOCN)","volume":"340 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117069479","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}

Both of these mechanism have certain advantages and disadvantages. VPN protocols, PPTP and IPsec were configured on the transition mechanism and compared with selected networking metrics. The key networking metrics that were captured in this research were through-put, delay, jitter, DNS throughput, DNS delay, DNS jitter, for both TCP and UDP protocols. VoIP throughput was also measured and discussed. The testbed consisted of two (IPv4/IPv6) capable Cisco routers, and two machines which were running Windows 7 and Windows Server 2012.","PeriodicalId":234041,"journal":{"name":"2016 Thirteenth International Conference on Wireless and Optical Communications Networks (WOCN)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132267706","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}

Simulation results indicate that a maximum of 162 Mbps-64QAM and 108 Mbps-16QAM signals can be sent simultaneously using Optical Single Side Band (OSSB) generation technique without any dispersion compensation. The proposed dual carrier multiplexing (DCM) architecture may be used for the multi-service transmission in heterogeneous networks. In presence of centralized control and processing, subcarrier multiplexing (SCM) techniques over fiber may provide economical and protocol-transparent solutions for the next-generation hybrid networks.","PeriodicalId":234041,"journal":{"name":"2016 Thirteenth International Conference on Wireless and Optical Communications Networks (WOCN)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129493060","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}

For testing purposes, we use pre-installed Wi-Fi access points and Beacon devices based on Bluetooth Low Energy (BLE) technology in our department for indoor positioning at the department. Using the classical RSSI based trilateration algorithm, we improved upon the location estimation using gradient descent over error function.

To operate them the user needs to physically press the switch to turn ON or OFF any appliance. This hassle of manually operating a switch is replaced by a smart technique which involves operating the switches using the web browser present in mobile phones, laptops or any other electronic gadgets. Smart switches already exist in the market today, but are very expensive and requires additional devices like hubs for their working. The current work makes use of a web App and a cloud to control the operation of the switches. A cloud server is created for the environment where the switches are mounted. The switches are interfaced with few electronic components such as logic gates, a 555 timer, flip-flops and a processor. The user communicates with the processor through the Web App. The processor then controls the switches based on the commands received from the user and also updates the user about the status of the switches after the control operation is performed to the cloud.","PeriodicalId":234041,"journal":{"name":"2016 Thirteenth International Conference on Wireless and Optical Communications Networks (WOCN)","volume":"1038 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123139533","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 our analysis, the method of moments (MoM) is used to compute the current distribution and directivity of the yagi antenna.
