A Survey on Link/Node-Disjoint On-Demand Multipath Routing Protocols in MANET
Ad-hoc wireless networks are self-organising, infrastructureless networks characterized by dynamic topology, limited channel bandwidth and limited battery power at the nodes. The nodes communication with each other through radio-links in multi-hop specified routing protocols. In recent years, multipath routing protocols have attracted the attention of several researchers due to their benefits like fault tolerance, load balancing, bandwidth aggregation, reduced delay, etc. Multipath routing allows the establishment of multiple paths between source and destination nodes. When a path breaks, an alternate path is used instead of initiating a new route discovery process.
