Abstract: The advent of Cloud computing & the rapid adoption of Cloud services (IaaS, PaaS, SaaS) by the consumer to fulfil their business requirements has flourished the market with various Cloud Service Providers (CSP). Cloud service providers are developing the desired environment and tools to serve the consumer’s needs. The consumers are facing the problem of selecting the appropriate Cloud service provider which can fulfil their need. This scenario which requires fast and controlled mechanism of managing resources, cost, capacity etc gives rise to the Cloud brokering system. The Cloud broker offers the opportunity to the consumer to get the best service as per service level agreement. In this paper, we are providing an overview of few Cloud brokerage models and there techniques used to select the best CSP from the pool of CSPs

Abstract: In recent years, wireless sensor networks (WSNs) featured an exponential growth, which has revolutionised the field of telecommunication. A wireless sensor network consists of a group of tiny battery powered sensor nodes capable of reading, processing and reporting the data to the Base station (sink).One of the major issues faced by sensor nodes is the energy constraint due to the limited energy sources in the form of tiny batteries. Therefore energy efficient data transfer presents the major challenge in a WSN. In this paper we investigate various Wavelet Transform based Effective Energy Utilisation approaches of data transfer in WSNs. These approaches can be used significantly to minimise the energy necessary for the efficient data communication in WSNs while meeting the constraints of data quality and bandwidth of wireless sensor networks
