Cognitive Radio (CR) networks are vulnerable to selfish attacks, where secondary users increase their accessing probability to enhance their own utilities, resulting in serious performance degradation in CR networks. Therefore, we formulate the secure access for CR networks into a static game called Back off Window Control Game (BWCG) and a repeated game with punishment mechanism based on the CSMA protocol. We have proven the existence of a Nash Equilibrium in the BWCG game and design a punishment mechanism to motivate selfish users not to perform selfish attacks in the repeated game. Simulation results show that the proposed scheme can improve the network performance and the punishment mechanism can efficiently prevent selfish attacks in CR networks.

Estimating and analyzing the power consuming features of a program on a hardware platform is important in High Performance Computing (HPC) program optimization. A reasonable evaluation can help to handle the critical design constraints at the level of software, choosing preferable algorithm in order to reach the best power performance. In this paper we illustrate a simple experimental method to examine SIMD computing on GPU and Multicore computers. By measuring the power of each component and analyzing the execution speed, power parameters are captured, the power consuming features are analyzed and concluded. Thereafter power efficiency of any scale of this SIMD computation on the platform can be simply evaluated based on the features. The precision of above approximation is examined and detailed error analysis has been provided. The power consumption prediction has been validated by comparative analysis on real systems.

The ALE is an interface of EPC network framework launched by EPCglobal, through which clients may obtain filtered consolidated EPC. The ALE provides a poll mode for creating a synchronous report. Under the EPC network framework the poll mode has to maintain atomicity for event cycle from different read cycle. It is big challenge for decentralized EPC network to long-term block channel for synchronous report. In this paper we propose two approach to make head against the challenge. The first way is to have storage in which relax the ALE engine for bursting in EPCs cycle after cycle. After all read cycle belong to same event cycle completed, the EPC engine sends EPC report to his consumer with asynchronous mode. The second strategy is to separate coarse event cycle into fine-grained cycle. After consumers receive all Sub-EPC report it reorganizes them into EPC report. We propose two algorithms and prove its efficient performance by simulation tool to show the performance efficiency.

The traditional relational database to online storage are becoming increasingly problematic: the low performance do not gracefully meet the needs of mass data, the storage approaches of massive data are still not perfect presents. NoSQL and distributed memory database technologies have the potential to simplify or eliminate many of these challenges. NoSQL database technologies can provide Key-value style of data storage and largely ensure high performance. Distributed memory database technologies provide a means for easily store mass data in cloud in a dynamic and scalable manner. This paper argues for a new architecture called CDSA, which is a distributed memory NoSQL database architecture for Cloud computing to improve the performance of querying data and ensure mass data storage in cloud by using rational strategy. Furthermore, add or deleted any node from the distributed database cluster, the others node can work without stop service. We believe that CDSA can provide durable storage with high throughput and lower access latency.

This paper presents the design scheme and implementation of a RF Signal Record & Playback System, which is able to record and store RF data directly from an active antenna or generate RF signals from data stored on a solid state drive. It introduces the organization and building components of the system, with a key emphasis on the design of system hardware, PCI Express bus interface and the DMA mode. By using the DMA mode, the continuous transfer rate of the bus is up to 1200Mbit/s. The experiment indicates that the system eliminates the bottleneck of real-time data acquisition and can be applicable to various kinds of RF signal especially the GPS navigation signal.

In this paper, an adaptive system is proposed which attempts to imitate a real market dynamics by combining together the approaches of studies of historical data and researches of multi-agent artificial market. The proportion of different agents is evolved by genetic algorithm in an artificial double auction market. The purpose of this research is to construct an artificial market which generates the dynamics of real market as similar as possible. The model with heterogeneous agents and the environment with which agents and market interact is complicated but controllable by data mining the optimal proportion of the different agents at the input to the market that generates an output which can fit historical data curve. The simulation results suggest that the system performance is close to the expecting values in the testing with adequate training in advance.

This research investigates the spatial properties of Bangladesh's literacy rates and educational establishments at the Zila level. The data is from the 64 well defined administrative units of Bangladesh known as Zilas. For autocorrelation we use univariate Moran's I and other various bivariate Exploratory Spatial Data Analysis (ESDA) techniques. Spatial clusters are found with Zilas that are surrounded with Zilas with high literacy rates. The results found from this research provide interesting and useful information to government, environmentalists and relevant decision makers' in the assessment of the relative performance of a particular geographic area. The results could also be used for causal analysis by domain experts.

Several works [1,2,3] have been reported in literature to cluster XML documents and/or XML Schemas based on structure similarity, semantic similarity, edit distance similarity etc. Our current attempt clusters the elements presented in an XML Schema based on conversion cost that incurs to transform one object to the other. Our strategy would help a dynamic XML compiler to reproduce classes for new elements in C# programming language by modifying existing classes rather generating those from the very beginning.

This paper compares aspect oriented approach using AspectJ with object oriented approach using Java programming in distributed environment and discusses the need to introduce aspects in Java RMI systems. These two approaches compared empirically using RMI auction System in Eclipse's framework in terms of various metrics. We developed RMI Auction System with AspectJ and Java languages in Eclipse's framework independently. There are certain properties like tracing, exception handling, distribution and profiling in Java RMI system which we cannot encapsulate properly using object oriented programming and lead to the problem of code tangling and code scattering. Therefore it is difficult to modularize them in separate functional modules. These properties are known as cross cutting concerns, which can be encapsulated into Aspect using Aspect Oriented Programming. In this, AspectJ language is used to encapsulate distributed cross cutting concern of RMI auction system in Eclipse supported framework. We have shown the comparison of AspectJ and Java through a RMI auction system in Eclipse Platform's Aspect visualizer and Metrics 1.3.6 plug-in.
