Abstract

Computational grid can perform the computationally extensive jobs by utilizing the wide spread processing capabilities of volunteer processors. In order to utilize the wide spread resources, failure options cannot be ignored. In this paper we give the detailed implementation of fault tolerance techniques, and also propose a modified forwarding mechanism which forwards the request to the next hop from which more receivers are available, the main contribution of this paper is the implementations of fault tolerant techniques using anycasting with modified forwarding mechanism and its analytical analysis for the computational grid. The study analyses the communication cost involved in the proposed scheme and its comparison with the previous techniques. The implementation of the computational grid is carried out in Alchemi toolkit which is based on Microsoft .Net framework.

Key words: Anycast, computational grid, communication cost.
