Nowadays, wireless sensor networks (WSNs) are becoming challenging issue and used in many fields and applications. WSNS are characterized by many constraints as low energy, low computation capability and weak transmission range. The cloud computing is promising technology that can provide a flexible storage and processing infrastructure to process WSN’s data in large scale. The two technologies (i.e.: WSNs, Cloud Computing) have gained significant research interest and their combining is a fundamental challenge that certainly will resolve many issues related to WSNs. In this paper we discuss firstly the idea of integrating WSNs in Cloud Computing starting with a state of the art analysis of existing approaches in this field. The second part of this paper is devoted to a comparative study between two efficient energy protocols that are proposed for WSNs.
Intellectual Capital is gaining importance in today's knowledge economy and plays a vital role in innovation, productivity growth, performance and competitiveness of organizations. The Intellectual Capital may include the following areas: human resources, organizational structure and processes, research and development, technology and rights related to intellectual property, and consumer networks and software providers. The purpose of this work is to measure the intellectual capital in an Algerian organization (or production system) using the Weightless Wealth Tool Kit “WWTK”. The results of the intellectual capital measurement are supplemented by traditional financial ratios. The measurement was applied to the National Company of wells Services (ENSP) in Hassi Messaoud city, in south of Algeria. We calculated the intellectual capital (intangible resources) of the ENSP to help the organization to better capitalize on its potential of workers and their know-how. The intangible value of the ENSP is evaluated at 16,936,173,345 DA in 2015.
