Furthermore, because recommender systems are used in various domains, there are very challenges when building them. So we are obliged to conduct requirements engineering which through it, better understanding of the system and requirements control to be achieved. So in this paper the process of determination of recommender system requirements in various domains has been analyzed and engineered, and in the end, a methodology for requirements engineering in recommender systems has been offered. To do this, we implemented one of the existent recommender systems, and at the next step, we built the same recommender system based on requirements engineering. In the end, we evaluated and compared the results of two recommender systems, one of them was built with and the other one without conducting requirements engineering by the use of “Precision”, “Recall” and “Response Time” metrics. While doing this study, a “RoadMap” and “Methodology” have been achieved, which we used them in another recommender system that the results of its evaluation has been presented too.","PeriodicalId":338914,"journal":{"name":"2017 9th International Conference on Information and Knowledge Technology (IKT)","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114248462","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 collaborative research activities have greatly been benefited by the availability of Open Research Data. The open data encourages transparency and democratic control by encouraging participation, facilitating selfempowerment and providing provisions for improved efficiency and effectiveness of government services and creation of new knowledge from existing data sets. The availability of Open Research data in different subject areas enhances research quality by encouraging broader visibility and sharing provisions among globally distributed community members. This scenario greatly encourages the economic re-usage of existing open research datasets in local research environments for timely and more precise comparative results. The paper thus attempts to analyse the open research data repositories in different setups available at re3 data registry and to ascertain various aspects like content type, access privileges, growth in terms of subject areas and countries, uploading and downloading facilities, data harvesting and retrieval provisions etc.","PeriodicalId":338914,"journal":{"name":"2017 9th International Conference on Information and Knowledge Technology (IKT)","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125547633","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 discovery of security threats are becoming a challenge to fulfill the purpose of the IoT ecosystem. Designing lightweight Authentication and Key Agreement (AKA) protocols are critical to establish mutual authentication while reducing overloads on particular constrained devices including Smart Meters. The Yan et al. lightweight AKA scheme was proposed to provide mutual authentication along with multicast mechanism and other features for Smart Grids which facilitates power management while maintaining it's security and privacy. However, in this paper we show that the Yan et al. lightweight AKA scheme is vulnerable to replay attack in the multicast key generation phase in which the control over Smart Meters could be lost. Specifically, in this scheme, the attacker is able to interrupt the multicast messages without revealing the interruption to the Building Area Network (BAN) gateway. So, the desired Smart Meters do not receive any emergency multicast messages during power outages for a while. So there is a disturbance in the Smart Grid that could result in a Denial of Service (DoS) attack.","PeriodicalId":338914,"journal":{"name":"2017 9th International Conference on Information and Knowledge Technology (IKT)","volume":"238 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130447268","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 these networks, the flying nodes in the mission must send their information to the ground base. If a UAV is outside the coverage of the ground base, it loses its connection. The solution is to send the information to the neighboring nodes. These neighboring nodes redirect the information to the ground base. Due to high node dynamics and rapid changes in network topology, one of the biggest concerns in these networks is routing between nodes. Previous routing methods, although making improvement in the overall performance in these networks led to routing overhead and network delay. In the present study a new routing method is introduced. In this new method a routing algorithm is presented with a focus on improving the packet delivery ratio and throughput therefore reducing the end to end delay and network overhead. In the proposed method instead of using only one route between nodes, all discovered routes in the network are kept in the nodes routing table. Then the best route is used as the first proposed route between the source and destination nodes and after failing this route, the second route is utilized immediately. This decreases the broadcasting of route discovery packets through the network. According the simulation results, the proposed method has proved more efficient. There has been an increase in packet delivery ratio by 4% in average, in end to end delay approximately by 30% and in the throughput ratio of the network by 9% in comparison with other methods in different scenarios.","PeriodicalId":338914,"journal":{"name":"2017 9th International Conference on Information and Knowledge Technology (IKT)","volume":"457 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121110785","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}
