Efficient allocation of channels for wireless communication in different network scenarios has become an extremely important topic of recent research. The main challenge lies in the fact that the… (More)

ÐThis paper introduces a new network topology, called Multi-Mesh (MM), which uses multiple meshes as the basic building blocks interconnected in a suitable manner. The proposed network consists of n… (More)

RC4, the widely used stream cipher, is well known for its simplicity and ease of implementation in software. In case of a special purpose hardware designed for RC4, the best known implementation till… (More)

In this paper, we derive the number of binary strings which contain, for a given ik, exactly ik runs of 1’s of length k in all possible binary strings of length n, 1 ≤ k ≤ n. Such a knowledge about… (More)

RC4 is the most popular stream cipher in the domain of cryptology. In this paper, we present a systematic study of the hardware implementation of RC4, and propose the fastest known architecture for… (More)

A cellular network is often modelled as a graph and the channel assignment problem is formulated as a coloring problem of the graph. In a recent paper [16], we introduced the notion of cellular… (More)

This paper presents an elegant technique for solving the channel assignment problem (CAP) for second generation (2G) cellular mobile networks, where channel allocation is made on a quasi-fixed basis… (More)
