Fuzzy based Load Distribution Scheme in MultiPath Routing

A scheme of disjoint path selection among overlapping paths has been explored here considering multiple QoS (Quality of Service) constraints, as the disjoint paths provide more reliability. QoS routing has become essential in today's scenario of Internet for the transmission of real time multimedia applications. Taking into account a list of available overlapping QoS constrained paths, we use the Fuzzy logic to find most optimal disjoint paths and also their preference order of optimality. On the basis of optimality proportion of selected disjoint paths, a new load distribution algorithm has been proposed.
