Abstract

This paper presents the various crosstalk avoidance algorithms in optical multistage interconnection network. The major problem introduced by optical multistage interconnection networks is crosstalk which is caused by the coupling of two signals within same switching element. To avoid a crosstalk, many approaches have been proposed such as time domain and space domain approaches. One way to solve this problem is to avoid coupling of two signals within same switching element. In this paper, various algorithms such as Window method, Improved Window method and Bitwise window method are implemented to avoid crosstalk. Window Method is used to find out which messages have conflict and it is also used to find the message that are not in same group because it causes crosstalk in the network. Then Improved window method is used in which first window is eliminated. Then Bitwise window method in which all the binary bits of single row in each window are converted to decimal so complexity is reduced.
