This new challenge is packet delivery. When nodes leave their cluster zone, they no longer can send data to the cluster head, and they have to find as soon as possible a new cluster head. By increasing mobility in the network, this situation becomes worse. To address this issue an adaptive protocol needed to reduce the packet loss by selecting better cluster heads and assign a new cluster head to mobile nodes in order to avoid more packet loss. In this paper we proposed MACP-FL, a mobility adaptive clustering protocol proposed for mobile wireless sensor networks. In setup phase of our protocol, we used FCM algorithm to divide the network into several clusters. The candidate cluster heads are selected based on three measures, residual energy, and membership function. When candidate cluster heads have been selected, by considering maximum radio range, suitable cluster head for each individual node selected based on estimated connection time between node and corresponding cluster heads. If a node is going to leave its cluster in transmission phase, it selects the new cluster head based on estimated connection time. Simulation results show that our method outperforms LEACH-M, LEACH-ME and MBC in terms of data delivery rate and energy consumption.","PeriodicalId":338953,"journal":{"name":"2015 7th Conference on Information and Knowledge Technology (IKT)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115735528","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}

These kinds of communications have become more organized subsequent to the emergence of social networks. One of the most important issues in analyzing these kinds of networks is community detection, in which most studies detect communities through analyzing linkages of the networks. The desirable goal in this paper is to reach communities in which the members have the same topic of interest, and where the strength of connections between them is the consequence of their communications' content analysis. Therefore, we propose a new framework which considers the information that is shared by the users, and also the topics they are interested in, in order to find more meaningful communities. While similar studies have only found communities by merely considering the topological structure of the network, and some of the features of semantic information related to the users of the network, like their topics of interest, the proposed framework detects communities through considering topics, communications' content and topological structure of the network. Quantitative evaluations indicate that the proposed framework achieves promising results which are superior in comparison with the other relevant frameworks in the literature.","PeriodicalId":338953,"journal":{"name":"2015 7th Conference on Information and Knowledge Technology (IKT)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128182773","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}

Recently, machine learning approaches, such as Hidden Markov Model (HMM) as well as hybrid methods, are frequently used to solve Name Entity Recognition. Since the absence of publicly available data sets for NER in Persian, as our knowledge does not exist any machine learning base Persian NER system. Because of HMM innate weaknesses, in this paper, we have used both Hidden Markov Model and rule-based method to recognize named entities in Persian texts. The combination of rule-based method and machine learning method results in a high accurate recognition. The proposed system in is machine learning section uses from HMM and Viterbi algorithms; and in its rule-based section employs a set of lexical resources and pattern bases for the recognition of named entities including the names of people, locations and organizations. During this study, we annotate our own training and testing data sets to use in the related phases. Our hybrid approach performs on Persian language with 89.73% precision, 82.44% recall, and 85.93% F-measure using an annotated test corpus including 32,606 tokens.","PeriodicalId":338953,"journal":{"name":"2015 7th Conference on Information and Knowledge Technology (IKT)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116969117","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 purpose of this method is auto identification of objects through tags attached to them. RFID system is created to ease data transfer about objects. An economic transfer was one of early goals of RFID systems, and this useful technology has entered other sectors of industry as well. Yet main concern in RFID systems is security and privacy. So far many protocols have been proposed to authenticate tags and readers but most of them are vulnerable. In year 2013, R. Doss et al. presented a low-weight protocol based on quadratic residues which provides secure channels between tag-reader and reader-server. In this paper we show that this protocol is vulnerable to replay attack and reader impersonation, and an attacker can authenticate itself to server as a legal tag or legal reader. So in this paper an improvement of this protocol is presented that is resistant to these attacks. Moreover, the proposed method has high speed and performance to do modular operations, because of the use of Montgo mery method.","PeriodicalId":338953,"journal":{"name":"2015 7th Conference on Information and Knowledge Technology (IKT)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128092592","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 technique, the image content is attached to a set of predefined switches. Content-Based Image Retrieval (CBIR) allows the users to retrieve the images efficiently. The image features are automatically extractable using image processing techniques. In this study, we proposed automatic image annotation using standardized color and texture called MPEG-7. These features include Color Layout Descriptor (CLD) and Scalable Color Descriptor (SCD) for colors and Edge Histogram Descriptor (EHD) for image texture. Moreover, to decrease the scope of color layout descriptor, we used Principal Components Analysis (PCA) and for classification we used Support Vector Machine (SVM). For an input search image, the above mentioned features are extracted and classification by Support Vector Machine and prepared to perform the image annotation. This system also presents the results of the comparison between different features from the MPEG-7 descriptors. The automatic image annotation which is presented in this study is related to TUDarmstadt images. The results confirm that the system is a reliable system which has both short vector length (maximum 400 elements for each image) and high precision of 90 percent.","PeriodicalId":338953,"journal":{"name":"2015 7th Conference on Information and Knowledge Technology (IKT)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123972382","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}
