The increasing popularity of multimedia networking applications such as e-learning has brought in more requirements in educational institutions for the students to learn online Current e-learning systems do not facilitate synchronous learning i.e., there is no interaction like that of a real class. However to impart effective learning, interaction between a student in the remote class-room and the teacher in the main classroom is mandatory. To enhance this virtual classroom, an automatic e-learning system is been proposed. Wireless technology which consists of collection of audio and video sensors tracks and identifies the speaker of interest in the classroom so that the lecturer on the other end will be able to effectively interact and can have a one to one communication with the focused student. We describe in this paper an automated system for student localization using audio and video processing, as a first step towards achieving such an automated system.","PeriodicalId":364589,"journal":{"name":"2012 Third International Conference on Computing, Communication and Networking Technologies (ICCCNT'12)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126557466","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 Distributed Sensor Network (DSN) is composed of intelligent sensors that are geographically dispersed in the region of interest and interconnected through a communication network. The (acoustic, seismic, and infrared) data by leaf sensor nodes are transmitted over the network and integrated at the processing element to derive appropriate interferences about the environment for different purposes, such as target tracking, location, surveillance and so on. Since a DSN is typically deployed for remote operations in unstructured area and the measurements are usually collected in a harsh, unreliable, and even adversarial environment, it is critical to provide extended networking capability to guarantee the performance of the entire system. In this work, we consider different contexts in distributed sensors network by considering the scenario of forest area such as: temperature context, air pressure context and object aware context. This work mainly focuses on routing the data from source to sink, and gathering and dissemination of related data. In this work, data aggregation is done in two phase: In first phase data is aggregated in Data Aggregator (DA) and in second phase data is aggregated in Master Aggregator (MA). If the context is in the emergency level then data is disseminated to target area. We simulated the context aware routing for data gathering and dissemination to test the operation scheme in terms of performance parameters.","PeriodicalId":364589,"journal":{"name":"2012 Third International Conference on Computing, Communication and Networking Technologies (ICCCNT'12)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127554194","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}

One possible solution consists in making use of mobile sinks. Sink mobility along a constrained path can improve the energy efficiency in wireless sensor networks. However, due to the path constraint, a mobile sink with constant speed has limited communication time to collect data from the sensor nodes deployed randomly. This poses significant challenges in jointly improving the amount of data collected and reducing the energy consumption. This paper propose a novel data collection scheme, called the Maximum Amount Shortest Path (MASP) using Improved Ant Colony Optimization, to address this issue, that increases network throughput as well as conserves energy by optimizing the assignment of sensor nodes. MASP is formulated as an integer linear programming problem and then solved with the help of improved ant colony optimization. Zone based partition is applied to implement the MASP scheme. The residual energy of each node is calculated and the optimal path is selected by considering the shortest path, residual energy, channel noise, and delay. This approach is validated through simulation experiments using NS2.","PeriodicalId":364589,"journal":{"name":"2012 Third International Conference on Computing, Communication and Networking Technologies (ICCCNT'12)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122662397","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}
