Abstract-The tremendous popularity of smart phones and electronic tablets has spurred the explosive growth of high-rate multimedia wireless services. To alleviate the huge infrastructure investment in the exponential growth of mobile traffic and improve local service flexibility, device-to-device (D2D) communications have been considered for the next generation mobile telecommunications. This has triggered investigation of fifth gernation (5G) to utilizes D2D communications for hetergenous networks. D2D communications enable users to transmit signals directly without going through the base station. However, many technical challenges need to be addressed for D2D communications to harvest the potential benefits. This requires learning how to improve the the model to better appeal to a wider base and move toward additional solutions. In this paper we provided a simple overview of D2D communications 5G hetergenous network by means of various Integer Linear programming. Finally, we present experiments on how Fractional knapsack using greedy algorithm can be used for power efficiency and improve throughput, thus allowing of future optimization problems.
The MESH-WISE project is aiming to address key fundamental issues in wireless mesh networking that span from fundamental performance characterization to prototyping heterogeneous-access mesh networking solutions for emergency response scenarios. In this paper we present the infrastructures that will be leveraged in this project and the latest results that have been acquired from the ones that are deployed. We further discuss the state of the art in academic and industrial resource and network management platforms and discuss how we will use existing know-how towards a centralized solution
Abstract-Smart Environments are environments where heterogeneous wireless networks are implemented and connected together both in terms of networking and in terms of functionalities, thus providing an abstraction layer to higher level applications that can exploit the interplay of such technologies to obtain killer features. In order to obtain real advantages from the integration of heterogeneous components the scenarios shall be clearly understood and analysed;therefore this paper classifies the different scenarios and network architectures that can be employed in creating a Smart Environment. Moreover, real life experimenting is needed, through testbeds and trial installations; our testbed is therefore described, as well as some results on the effects achieved by interconnecting different technologies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
