Route failure tolerant multicast in Mobile Ad Hoc Networks using disjoint minimum spanning trees

In this paper, we study the problem of constructing minimum cost multicast trees and computing multiple multicast paths. Due to the lack of redundancy in multi-path and multicast structures, the multicast routing protocols are vulnerable to the failure in ad-hoc networks. So it is the dire need to come across the fault tolerant solution. This paper proposes edge disjoint spanning tree based multicasting in ad-hoc networks for route failure tolerance.
