In near future, billions of devices are expected to be connected to IoT through wireless connections. Due to the limited capacity of the wireless medium, the effective resource allocation is a highly important factor to improve the network performance, especially in the presence of a large number of devices. In this work, we investigate the problem of allocating resources in an OFDMA-based wireless IoT network, including channel assignment and power control, to satisfy the SINR requirements of all the devices in a scalable manner. The Primary Resource Allocation Problem (PRAP) is formulated as a Mixed-Integer Linear Programming (MILP) problem which is efficiently solvable by mathematical methods. We next develop a new relay-based communication model that results in a significantly improved network performance. The resource allocation in this model is formulated as the Relay-based Resource Allocation Problem (RRAP). Due to their computational complexity, the Relay-based Resource Allocation Scheme (RRAS) is devised to provide a suboptimal solution for RRAP and PRAP. The numerical results show that the relay-based communication model results in highly improved SINR for devices, network outage ratio, and transmission power.","PeriodicalId":220153,"journal":{"name":"2016 International Conference on Information Technology (ICIT)","volume":"95 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116645089","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}

Most of the service providers are changing their server storage to cloud storage. It is a great challenge for the service provider to attract the customers to store their sensitive data/file in the cloud storage. Service provisioning with respect to privacy preservation and data security is an area of concern. In general the cloud servers are being deployed on different trusted domain by different data owner. There will be need to encrypt sensitive data and store them in cloud server and disclose decryption key to authorized users. But drawback of this method is that owner of file can selectively share data by sharing his private key. Most of the computation for key distribution and management are done by the data owner. T here are various fine-grained access control models for sharing of encrypted data on cloud server. Some of these model used key policy Attribute Based Encryption (KP-ABE) and others used Cipher text Policy Attribute Based Encryption (CP-ABE). These techniques can be used to keep shared data confidential even if data is stored on remote server. These models are used to define and enforcing access control policy based on attributes and delegates most of the computation task involved in fine grained access control without disclosing data to storage server. This paper under takes critical study on available access control approaches that has been deployed in cloud computing environment.","PeriodicalId":220153,"journal":{"name":"2016 International Conference on Information Technology (ICIT)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124381584","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}

Multicast Routing and Spectrum assignment (MRSA) in Flexible-Grid Optical Networks (alternately Elastic Optical Networks) generates a multicast tree for each multicast session request and spectrum frequency slots are allocated to each of the edge of the multicast tree. Orthogonal Frequency Division Multiplexing (OFDM) technique can be used to implement MRSA algorithm. Spectrum frequency slots are allocated to the edges of the multicast tree obeying the spectrum continuity constraint and spectrum contiguity constraint, thus creating a multicast light-tree. In this paper we have proposed a lighttreesharing based multicast routing and spectrum assignment technique. Similar multicast requests are grouped together and their bandwidth requirements are added up. For each multicast session request a layered auxiliary graph is selected based on available spectrum in the network and the request's bandwidth demand. An efficient light-tree is generated from this auxiliary graph, first for the clubbed request and then for the individual requests separately. The simulation results show that our proposed algorithm significantly reduce the average tree size and increases number of requests satisfied than the well-known existing algorithm mentioned in literature. Incidentally the average number of splitters required is also reduced.","PeriodicalId":220153,"journal":{"name":"2016 International Conference on Information Technology (ICIT)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132347484","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}

A lossless LZ77 data compression technique is used here in order to retain the information content by removing data redundancy and also employs a text window in congestion with look-ahead buffer to serve as a dictionary. In the proposed technique the unmatched string present in the dictionary are encoded as a length and offset. Encoding and decoding process in data compression enables SSD's, so that the data written is less in turn yields the endurance of SSD performance. Eventually using novel method, pointers are effectively selected and encoded for the longest matched string to obtain greater compression. For the unmatched character compression ratio is 3.12times which is better than existing algorithm. Data compression improves the performance of SSD, hence this reduces the amount of data transfer to flash memory. The speed of secure data compression increases with a creation of preferred search function for a HEX sample data size 32Kbyte. Even though if extra time is acquired, asymmetric compression decompresses the data quickly resulting in good compression.","PeriodicalId":220153,"journal":{"name":"2016 International Conference on Information Technology (ICIT)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127748346","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 present study focus on the applications of data mining techniques in tea plantations in the face of climatic change to help the farmer in taking decision for farming and achieving the expected economic return. This paper presents an analysis using data mining techniques for estimating the future yield prediction in tea cultivation with climatic change trends observed in last 30 years (1977-2006). The patterns of crop production in response to the climatic (rainfall, temperature, relative humidity, evaporation and sunshine) effect across the four tea growing regions (South Bank, North Bank, Upper Assam and Cachar) of Assam were developed using Multiple Linear Regression (MLR) technique. The tea production estimation equations developed for the regions were validated for the future yield prediction (2007, 2009 and 2010) and were found to be significant. Thus it is suggested that the planters/farmers could use the technique to predict the future crop productivity and consequently adopt alternative adaptive measures to maximize yield if the predictions fall below expectations and commercial viability.","PeriodicalId":220153,"journal":{"name":"2016 International Conference on Information Technology (ICIT)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123332431","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 problem with encrypting data is we have to decrypt it for applying operations on files such as altering a word document or querying a statistical database containing financial data. Decrypting the data will leave it vulnerable. If we want to perform conditional based search queries in an encrypted data entire data should be decrypted to perform it, unless an order preserving scheme is used. There is no homomorphic encryption scheme which will allow us to perform conditional based queries without decrypting the entire data. In mathematical term homomorphic describes the changeover of one data set into another upholding the association between elements in both sets. Order Preserving Encryption (OPE) schemes are used extensively used in cryptography because of their usage in database design. But there is a chances of inference attack in case of OPE. In this paper we had proposed and implemented a technique which will allow to perform conditional based search queries in the data encrypted using any encryption algorithm with log(n) decryption, thereby reducing complexity.","PeriodicalId":220153,"journal":{"name":"2016 International Conference on Information Technology (ICIT)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126778136","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}
