چکیده

In this paper we consider the problem of distributed leader election in unoriented Abelian Cayley graphs of degree 4. This family of graphs, denoted by C G 4, include bidimensional tori of arbitrary size and chordal rings with one arbitrary chord. We present an algorithm which assumes that the only structural knowledge available to the nodes is “I am in an Abelian Cayley Graph of degree 4”. The message complexity of our algorithm, for a graph of C G 4 of order N and diameter D, is O(N +D log D2 N ). The obliviousness of our algorithm to the underlying topology has been achieved by studying the properties of tessellations of the plane and reducing the problem of leader election in a graph from C G 4 to election in the associated tessellation.

NORMAL 6-VALENT CAYLEY GRAPHS OF ABELIAN GROUPS

Abstract : We call a Cayley graph Γ = Cay (G, S) normal for G, if the right regular representation R(G) of G is normal in the full automorphism group of Aut(Γ). In this paper, a classification of all non-normal Cayley graphs of finite abelian group with valency 6 was presented.

On the distance eigenvalues of Cayley graphs

In this paper, we determine the distance matrix and its characteristic polynomial of a Cayley graph over a group G in terms of irreducible representations of G. We give exact formulas for n-prisms, hexagonal torus network and cubic Cayley graphs over abelian groups. We construct an innite family of distance integral Cayley graphs. Also we prove that a nite abelian group G admits a connected...

Leader Election by d Dimensional Cellular Automata

We present a cellular algorithm in O(w) for the leader election problem on a finite connected subset F of ZZ of excentricity w, for any fixed d. The problem consists in finding an algorithm such that when setting the elements of F to a special state, and all the others to a state #, the cellular automaton iterates a finite number of steps and eventually sets only one precise element of F to a s...
