With improvement in technology, there is huge migration of business applications to cloud. Performance evaluation of cloud computing infrastructure is required to predict and quantify the cost-benefit of a strategy portfolio and the corresponding Quality-of-Service (QoS) experienced by users. Such analyses are not feasible by simulation or on-the-field experimentation, due to great numbers of parameters ...

Wireless Sensor Networks (WSNs) are a valuable technology to support countless applications in different areas. Given the WSN nodes resource constrained characteristics, designing energy-aware applications, communication protocols and security mechanisms are critical. The Operating System (OS) running on the WSN node also interferes with the node overall behavior and its energy consumption. In view of ...

In this paper, the authors introduce the Bit Error Rate (BER) simulation using 16 QAM (Quadrature Amplitude Modulation) in Matlab. Bit error rate is used to assess systems which can transmit digital data from one address to other address. BER is a unit-less performance measure, often expressed as a percentage. There are few systems where ...

The two types of wireless network are infrastructure and infrastructure less network. In infrastructure wireless network, base stations are fixed. Nodes moves randomly in the wireless environment and node communication takes place with the help of base station. A Mobile Ad hoc NETwork (MANET) is a continuously self-configuring and infrastructure less network of mobile devices. ...

The EEPROM, ADC and RTC will require an interface for communication between them. Due to that I2C bus is used as an interface between EPROM, ADC and RTC. It is used to minimize system-level interconnect. This simplifies the system level design and the design of the mother-board and associated chip-boards. The I2C protocol was given ...

In preview of the skill shortages mushrooming across the globe, trepidations exist for retaining the Generation Y employees and addressing their expectations. With this cohort on the prowl for taking the business organizations to a new zenith of success, it is paramount for employers to understand the basic characteristics, expectations and preferences of such employees. ...
