ABSTRACT: Reliability of tree-like multicast overlays caused by nodes’ sudden failures is considered as one of the significant issues for the Internet application-layer media streaming service. In this project, we address this issue by designing a distributed and light-weighted protocol named the instantaneous reliability oriented protocol (IRP). Not at all like the greater part of […]
ABSTRACT: The project objective for securing the software given to the clients with the end goal that the application runs just for the specific count, up to a date, number of days starting from the installation date, keeps running in one machine. The application if copied to other systems won’t work. During first run, a license key […]
ABSTRACT: In recent years ad hoc parallel data processing has emerged to be one of the killers for Infrastructure-as-a-Service (IaaS) clouds. Real Cloud computing companies have started to integrate systems for parallel data processing in their item portfolio, making it simple for clients to get to these services and to deploy their programs. However, the processing structures […]
ABSTRACT: Search engine companies gather the “database of intentions,” the histories of their clients’ search queries. These search logs are a gold mine for researchers. Search engine companies, in any case, are careful about publishing search logs order not to disclose sensitive information. In this project, we analyse the algorithm for publishing frequent keywords, queries, and clicks […]
ABSTRACT: In this project, we are interested with wireless scheduling algorithms for the downlink of a single cell that can minimize the queue overflow probability. In particular, in a large deviation setting, we are interested in algorithms that maximize the asymptotic decay rate of the queue overflow probability, as the queue overflow threshold approaches infinity. We […]
ABSTRACT: Compromised node and denial of service are two key attacks in wireless sensor networks (WSNs). In this project, we study routing components that circumvent (bypass) block holes formed by these attacks. We contend that current multi-path routing approaches are vulnerable against such attacks, for the most part, because of their deterministic nature. So once […]
ABSTRACT: In this project, we investigate single client throughput optimization High-Speed Downlink Packet Access (HSDPA). In particular, we propose offline and online optimization algorithms which modify the Channel Quality Indicator (CQI) utilized by the system for scheduling of data transmission. In the offline algorithm, a given target block error rate (BLER) is accomplished by changing […]
ABSTRACT: Cooperative communication has received tremendous interest for wireless networks. Most existing works on cooperative communications are focused on link level physical layer issues. Thusly, the impacts of cooperative communications on network level upper layer issues, for example, topology control, routing, and network capacity, are largely ignored. In this article, we propose a Capacity-Optimized Cooperative […]
ABSTRACT: In this project, we have the new approach for encryption of different file formats like text, image, audio and video with key wrapping is proposed. The binary data of a record is separated into an equal size with estimated blocks called as girds. The bit stream of each gird is taken and Square gird transposition is applied. A variable […]
ABSTRACT: We focus on a two-tier sensor coordinate with the resource-rich master nodes at the upper tier and resource poor sensor nodes at the lower tier. Master nodes gather information from sensor nodes and answer the queries from the network proprietor. The reliance on mater nodes for information storage and query processing raises serious concerns […]
