Though the number of context-aware applications is increasing day by day along with the users, there is no generic programming paradigm for context-aware applications. This situation could be remedied by designing and developing an appropriate context modeling and programming paradigm for...

A simple continuous model is used to understand virus attacks on computers through Ordinary Differential Equations (ODE). The persistence of computer virus is a great threat to the computer user community. In the light of this, researchers have taken an increasing amount of interest on modeling...

The Rabin cryptosystem is an asymmetric cryptographic technique whose security, like that of RSA, is related to the difficulty of factorization. Rabin Cryptosystem was designed by Michael O Rabin in January 1979. In this asymmetric cryptosystem, recovering the plaintext from the ciphertext is...

In this paper, we analyze the compression ratio achieved by Huffman coding with that of uniform coding. For this, we first study the skewness property of the Huffman coding tree. We demonstrate that this tree will be completely skewed when the sorted frequency distribution of characters...

Performance measurement is a fundamental building block of total quality management and a total quality organization. It is a measurement indicator for software development projects to define, understand, collect and analyze data, and prioritize through valid comparisons and make appropriate...

Inventory management is considered to be an important field in supply chain management. Inventory is one of the factors responsible for minimizing the supply chain cost. Through efficient and effective management of inventory, services provided to the customers get enhanced. In this paper, an...

Although numerous context-aware applications have been developed and there have been technological advances for acquiring contextual information, it is still difficult to develop and prototype interesting context-aware applications. In this paper, we present a Graphic User Interface (GUI)-based...

Mobile ad hoc network—an instantaneous, easily deployable and infrastructureless network— paves way for many applications in this ever widening communication world. The important aspect lies in securing Mobile Ad Hoc Network (MANET) due to its decentralized architecture, dynamic topology and...

In this paper, we consider the inference problem for monotone Boolean structure functions (for example, Torvik and Triantaphyllou, 2002 and 2005; or Judson et al., 2005). We follow Judson’s algorithm (in Judson, 1999; or Judson et al., 2005), except with two possible changes. First, when choosing a...

The paper proposes mobile agent-based data gathering from Wireless Sensor Network (WSN) to monitor any application and when an event is sensed, it notifies the user via message and call. The WSN is divided into three clusters, each cluster having a master section head. The mobile agent created...
