In this paper we are presenting a novel approach that enables the rendering of large-shared datasets at interactive rates using inexpensive workstations. Our algorithm is based on view-dependent rendering and client-server technology — servers host large datasets and manage the selection of the various levels of detail, while clients receive blocks of update operations which are used to generate the appropriate level of detail in an incremental manner. We assume that servers are capable machines in terms of storage capacity and computational power and clients are inexpensive workstations which have limited 3D rendering capabilities. For optimization purposes we have developed two similar approaches — one for local area networks and the other for wide area networks. For the second approach we have performed several changes to adapt to the limitation of the wide area networks. To avoid network latency we have developed two powerful mechanisms that cache the adapt operation blocks on the clients' side and predict the future view-parameters of clients based on their recent behavior. Our approach dramatically reduces the amount of memory used by each client and the entire computing system since the dataset is stored only once in the local memory of the server. In addition, it decreases the load on the network as a result of the incremental update contributed by view-dependent rendering.

Using Data

Cloud is a term used as a metaphor for the wide area networks (like internet) or any such large networked environment. It came partly from the cloud-like symbol used to represent the complexities of the networks in the schematic diagrams. It represents all the complexities of the network which may include everything from cables, routers, servers, data centers and all such other devices. Cloud based systems saves data off multiple organizations on shared hardware systems. Data segregation is done by encrypting data of users, but encryption is not complete solution. In the proposed work, we have tried to increase the cloud security by using encryption algorithms like AES and RSA along with OTP authentication. We have also fragmented the data by using data distribution at the server end.

The Internet Of Things

In the last years, the Internet of Things (IoT) has emerged as a key application context in the design and evolution of technologies in the transition toward a 5G ecosystem. More and more IoT technologies have entered the market and represent important enablers in the deployment of networks of interconnected devices. As network and spatial device densities grow, energy efficiency and consumption are becoming an important aspect in analyzing the performance and suitability of different technologies. In this framework, this survey presents an extensive review of IoT technologies, including both Low-Power Short-Area Networks (LPSANs) and Low-Power Wide-Area Networks (LPWANs), from the perspective of energy efficiency and power consumption. Existing consumption models and energy efficiency mechanisms are categorized, analyzed and discussed, in order to highlight the main trends proposed in literature and standards toward achieving energy-efficient IoT networks. Current limitations and open challenges are also discussed, aiming at highlighting new possible research directions.
