Multi Constraint Multicasting Analysis with Fault Tolerance Routing Mechanism

Abstract

Random mobile nodes with minimal mobility make up the popular and demanding mobile ad
hoc network (MANET). The network’s major challenges are ensuring fault tolerance and
increasing reliability. During the route maintenance procedure, existing works failed to
balance link tolerance and the reliability of nodes. More tolerance and longer network
lifetime is achieved by the use of a fuzzy-based Fault Tolerant Routing Protocol (FFTRP).
Network model for mobility and scalability is designed in the first module, whereas in second
module, a path reliability-based multicast routing is developed. The Fault-tolerant
computation and multicast routing integration are completed in the third phase. Because of
these uncertainties, determining the best route from the source to a set of receiving terminals
is difficult. To conserve network resources, we used a fuzzy logic technique to try and control
these uncertainties. This technique combines all of the route’s network characteristics into a
single statistic, the “fuzzy cost” or “communication cost”. Using the paths with the lowest
fuzzy costs, the data is distributed to a group of receivers. In this NS-2 and MATLAB
investigation, the proposed EFMMRP outperformed other protocols in terms of packet
delivery latency, control overhead and packet delivery ratio.
