During the query and data dissemination phases, optimal routing is a vital role since the multimedia content is conditional to strict QoS requirements. But the existing works on Multipath routing rarely consider losses and delay at the sink leading to energy degradation, involve unnecessary additional paths which cause high overhead. To overcome these issues, in this paper, we proposed an adaptive multi constraint Multipath routing protocol which minimizes loss rate, energy consumption and delay. We consider a cluster based architecture where inter cluster routing is performed based on a weighted cost function. The cost function is based on the parameters such as loss rate, residual energy and delay. In order to save energy, nodes which don't take part in routing are put to sleep mode. The simulation results prove that the proposed protocol is efficient in terms of energy efficiency, delay and packet delivery ratio when compared to the QoS aware routing from the literature.","PeriodicalId":429916,"journal":{"name":"2012 International Conference on Computing Sciences","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122352552","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 most predicament issue that happens in WSN is Congestion. Congestion causes packet loss, which in turn reduces throughput and energy efficiency. Therefore congestion in WSNâs needs to be controlled for high energy-efficiency, to prolong system lifetime, improve fairness, and improve quality of service (QoS) in terms of throughput (or link utilization) and packet loss ratio along with the packet delay. This paper proposes a new protocol for data delivery into high congested areas. Proposed algorithm provides an efficient way to overcome congestion in wireless cluster sensor network. Proposed algorithm provides priority both on data and location.","PeriodicalId":429916,"journal":{"name":"2012 International Conference on Computing Sciences","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128890293","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}

Many new services have been introduced which leads the popularity of the internet to next level, for example VoIP (Voice over Internet), E-Banking, Telepresence etc. Uninterrupted service is the most important requirement of the computer networks, the main reason behind this requirement is dependency on computer networks. Uninterrupted service or high availability can be achieved through redundancy and Redundancy Protocols, Redundancy can be achieved easily but efficient use of available resources is somewhat difficult task. So in this paper we will discuss a new redundancy mechanism which tries to use available resources efficiently, and make networks more fault tolerant.","PeriodicalId":429916,"journal":{"name":"2012 International Conference on Computing Sciences","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115391075","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}

Usually big stores have secure SSL [1] connections to be used by the owners of credit cards. Use of base64 encoding instead of hexadecimal and similarly using AES-128[2] cipher algorithm certainly heightens database security because these methods ensure high security where as they shorten the length of the encrypted string. Carrying forward these two above stated methods i.e. base64 encoding and AES-128 cipher algorithm, a more secure approach will be to use random number generator in which is required only to store the 8-byte random component instead of full 16 bytes. The existing methods of encryption are also not fool proof for high end professionals. The main thrust of this paper is to identify, pinpoint and find the solutions for the inherent dangers involved in the database storage.","PeriodicalId":429916,"journal":{"name":"2012 International Conference on Computing Sciences","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125207760","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 two dominant approaches used for storing and managing database are centralized database management system and distributed database management system in which data is placed at central location and distributed over several locations respectively. Independent of the database approach used, one of the foremost issue in the database is the retrieval of data by using multiple table from central repository in centralized database and from number of sites in distributed database. Joins and semi joins are primitive operations used to extract required information from one, two or multiple tables. In this paper the focus is given on computing and analyzing the performance of joins and semi joins in centralized as well as in distributed database system. The various metrics that will be considered while analyzing performance of join and semi join in centralized database and distributed database system are Query Cost, Memory used, CPU Cost, Input Output Cost, Sort Operations, Data Transmission, Total Time and Response Time. In short the intention of this study is compare and contrasts the behavior join and semi-join approach in centralized and distributed database system.","PeriodicalId":429916,"journal":{"name":"2012 International Conference on Computing Sciences","volume":"187 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124738103","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}
