Web services facilitate integration and interoperability of distributed heterogeneous application and components. It is a standard representation for information resource that can be used by other programs, regardless of the development platform, middleware, operating system and the hardware. During execution of a web service, there is a need to monitor its internal behavior to check for its av...

The heterogeneous deployment of high-power macro cells and low-power nodes (LPNs) is now widely acknowledged as an essential requirement towards meeting the continued demand for mobile data capacity. The selection of the optimum backhaul solution for the LPNs obliges operators to consider not only the capacity of the backhaul but also other key factors so as to fully leverage the benefits provi...

Network throughput is scaling-up to higher data rates while end-system processors are scaling-out to multiple cores. In order to optimize high speed data transfer intomulticore end-systems, techniques such as network adaptor offloads and performance tuning have received a great deal of attention. Furthermore, several methods of multi-threading the network receive process have been proposed. How...

The sensor nodes are typically resource deficient with energy being the most critical of all the resources. The nodes in a WSN are connected typically to a powerful controlling node called the base station. The base station is generally assumed to be connected to a stable power source and is not considered energy deficient, whereas all other nodes are battery powered. So, efficient use of energ...

Internet services like the world-wide web and multimedia applications like Newsand Video-on-Demand have become very popular over the last years. Since a high and rapidly increasing number of users retrieve multimedia data with high data rates, the data servers can represent a severe bottleneck. Traditional time and resource consuming operations, like memory copy operations, limit the number of ...
