A Node Disjoint Multipath Routing Protocol in Mobile Ad Hoc Network

The applications of Mobile Ad hoc Network (MANET) are based on all-IP architecture. In MANET, the applications place stringent requirements on networks for delivering data packets reliably and quickly. Mobile ad hoc networks are characterized by a dynamic topology, limited channel bandwidth and limited power at the nodes. Because of these characteristics, paths connecting source nodes with destinations may be very unstable and go down at any time, making communication over ad hoc networks difficult. Typical applications may require higher reliability connections than that provided by a single link. Also, to fulfill certain quality parameters; presence of multiple node-disjoint paths becomes beneficial. Such paths aid in the optimal traffic distribution and reliability in case of path breakages. Thus, to cater these challenges of routing in Mobile Ad hoc Networks, a Node Disjoint Multipath Routing protocol considering high mobility in MANET has been proposed by the authors. This protocol can discover multiple node-disjoint route paths with low routing overhead, so it can provide load balancing and higher aggregate bandwidth.
