With the significant advances in Information and Communications Technology (ICT) over the last half century, there is an increasingly perceived vision that computing will one day be the 5th utility (after water, electricity, gas and telephony). This computing utility, like all other four existing utilities, will provide the basic level of computing service that is ...
Recent human-computer interaction studies focus on natural interface based on hand/finger movements by tracking body motion using various sensors. In this paper, the authors propose ‘Surface gesture’ recognition method using both 2D surface information and 3D spatial information. ‘Surface gesture’ is composed of continuous gestures using 2D and 3D coordinates in multi spaces. They use ...
In MANET mobile node is responsible for route establishment using wireless link where each node behave like both as a host and router. MANET encounter by number of security threat because of its open untrusted environment with little security arrangement, whether security over MANET is not to be enhance up to satisfactory level because of ...
Since the advent of operating system, the focus of the paper is aimed at better resource scheduling. Handling of multiple tasks at a single time by single processor is old story now. Today is the time of multitasking as well as multiprocessing. The scheduling of processes or tasks have taken a whirlwind after the concept ...
One of the principal challenges of resource sharing on data communication network is its security. This is premised on the fact that once there is connectivity between computers sharing some resources, the issue of data security becomes critical. This paper presents a design of data encryption and decryption in a network environment using RSA algorithm ...
System identification is the art and science of building mathematical models of dynamic systems from observed input-output data .This paper combines Particle Swarm Optimization Algorithm and LMS algorithm to describe the application of a Particle Swarm Optimization (PSO) to the problem of parameter optimization for an adaptive Finite Impulse Response (FIR) filter. LMS algorithm computes ...
The application of technological and related procedures to safeguard the security of various documents while moving on the channel is an important responsibility in electronic data systems. This paper specifies the modification of the Data Encryption Standard (DES) and the Triple Data Encryption Algorithm (TDEA) which may organizations to protect sensitive data. Protection of data ...
SMS is one of the most widely used data applications in the world. Due to its easy availability and low cost, many enterprises have chosen to use SMS as the primary medium for dissemination of information and alerts. During high loads and traffic scenarios, the SMS latency tends to rise exponentially, which is a concerning ...
Orthogonal Frequency Division Multiplexing (OFDM) is a modulation schema that due to the high spectral efficiency and the simplicity of the receiver implementation is the most common system for using in broadband communication systems. Although OFDM has been used in numerous wireless communication systems, but two of the main problems that are needed to be ...
Camouflage of malware is a serious challenge for antivirus experts and code analysts. Malware use various techniques to camouflage them to not be easily visible and make their lifetime as longer as possible. Although, camouflage approaches cannot fully stop the analyzing and fighting against the malware, but it make the process of analyzing and detection ...
