Wireless sensor networks (WSNs) have many applications in the areas of commercial, military and environmental requirements. Regarding the deployment of low cost sensor nodes with restricted energy resources, these networks face a lot of security challenges. A basic approach for preparing a secure wireless communication in WSNs, is to propose an efficient cryptographic key management protocol be...

 Objective(s): Lymph node metastases are the most significant prognostic factor in localized non-small cell lung cancer (NSCLC). Identification of the first nodal drainage site (sentinel node) may improve detection of metastatic nodes. Extended surgeries, such as lobectomy or pneumonectomy with lymph node dissection, are among the therapeutic options of higher acceptab...

Wide area research has been done in MANETs, with a major focus on the routing protocols in MANETs i.e AODV, DSR, OLSR and so many others. Much research has been done using different tools to study and analyze the performance of the routing protocols in MANET. Different results are shown by the different simulation environments depending on the number of mobile nodes, mobile node speed and varyi...

Mobile ad hoc network is a collection of mobile nodes communicating through wireless channels without any existing network infrastructure or centralized administration. Because of the limited transmission range of wireless network interfaces, multiple "hops" may be needed to exchange data across the network. Consequently, many routing algorithms have come into existence to satisfy the needs of ...

Multiprocessors and high performance networks allow to build CLUsters of MultiProcessors (CLUMPs). A main distinctive feature over traditional parallel computers is their hybrid memory model (message passing between the nodes and shared memory inside the nodes). We evaluate the performance of a cluster of 2-way SMP PCs connected by a Myrinet network for NAS benchmarks from two programming: a Si...

WiFi offloading has emerged as a key component of cellular operator strategy to meet the data needs of rich, mobile devices. As such, mobile devices tend to aggressively seek out WiFi in order to provide improved user Quality of Experience (QoE) and cellular capacity relief. For home and work environments, aggressive WiFi scans can significantly improve the speed on which mobile nodes join the ...

Neo-fuzzy elements are used as nodes for an evolving cascade system. The proposed system can tune both its parameters and architecture in an online mode. It can be used for solving a wide range of Data Mining tasks (namely time series forecasting). The evolving cascade system with neo-fuzzy nodes can process rather large data sets with high speed and effectiveness.

We propose a new technique called node sampling to speed up the probability-based power estimation methods. I t samples and processes only a small portion of total nodes to estimate the power consumption of a circuit. It is different from the previous speed-up techniques for probability-based methods in that the previous techniques reduce the processing time for each node while our method reduc...

MANETs (Mobile Ad-hoc Networks) are self organizing networks without the need for a pre-existing infrastructure. These characteristics make them suitable for situations as rescue procedures, education, and military. When nodes need one-to-many or many-to-many communication then multicasting is employed. Many experiments showed that ODMRP protocol is very efficiency.. In this article we partitio...

background & objectives: colon cancer is currently of high incidence and mortality rate. identifying the factors influencing its prognosis can be very beneficial to its clinical treatment. recent studies have shown that lymph nodes ratio can be considered as an important prognostic factor. the aim of the present study is to investigate the effect of this factor on the prognosis of the patie...
