چکیده

It is well known that star graphs are strongly resilient like the n cubes in the sense that they are optimally fault tolerant and the fault diameter is increased only by one in the presence of maximum number of allowable faults [Lat93b, RS93]. We investigate star graphs under the conditions of forbidden faulty sets [Esf89] where all the neighbors of any node cannot be faulty simultaneously; we show that under these conditions star graphs can tolerate upto (2n 5) faulty nodes and the fault diameter is increased only by 2 in the worst case in presence of maximum number of faults. Thus, star graphs enjoy the similar property of strong resilience under forbidden faulty sets like the n-cubes [Lat93a]. We have developedalgorithms to trace the vertex disjoint paths under different conditions.

A Deterministic Multiple Key Space Scheme for Wireless Sensor Networks via Combinatorial Designs

The establishing of a pairwise key between two nodes for encryption in a wireless sensor network is a challenging issue. To do this, we propose a new deterministic key pre-distribution scheme which has modified the multiple key space scheme (MKSS). In the MKSS, the authors define two random parameters to make better resilience than existing schemes. Instead of a random selection of these parame...

خواص متریک و ترکیبیاتی مکعب‌های فیبوناتچی و لوکاس

An n-dimensional hypercube, Q_n, is a graph in which vertices are binary strings of length n where two vertices are adjacent if they differ in exactly one coordinate. Hypercubes and their subgraphs have a lot of applications in different fields of science, specially in computer science. This is the reason why they have been investigated by many authors during the years. Some of their subgraphs ...

Detection of Fake Accounts in Social Networks Based on One Class Classification

Detection of fake accounts on social networks is a challenging process. The previous methods in identification of fake accounts have not considered the strength of the users’ communications, hence reducing their efficiency. In this work, we are going to present a detection method based on the users’ similarities considering the network communications of the users. In the first step, similarity ...

The spectrum of the hyper-star graphs and their line graphs

Let n 1 be an integer. The hypercube Qn is the graph whose vertex set isf0;1gn, where two n-tuples are adjacent if they differ in precisely one coordinate. This graph has many applications in Computer sciences and other area of sciences. Inthe graph Qn, the layer Lk is the set of vertices with exactly k 1’s, namely, vertices ofweight k, 1 k n. The hyper-star graph B(n;k) is...

Emulation of a PRAM on Leveled Networks

We present efficient emulations of the CRCW PRAM on a large class of processor interconnection networks called leveled networks. This class includes the star graph and the n-way shuffle, which have the interesting property that the network diameter is sub-logarithmic in the network size. We show that a CRCW PRAM can be emulated optimally on these networks (i.e., each emulation step takes time l...
