RBU+: Recursive Binding Update for End-to-End Route Optimization in Nested Mobile Networks

In this paper, we propose an end-to-end route optimization scheme for nested mobile networks, which we refer to as Recursive Binding Update plus (RBU+). A nested mobile network is a hierarchical form of mobile networks. Nested mobile networks suffer from a pinball routing problem with hierarchical mobile routers. This problem becomes more serious in the case of macro mobility, as the routing distance becomes longer. To solve the pinball routing problem of nested mobile networks, in this paper we propose the Recursive Binding Update (RBU) and three distinct solutions for the end-to-end routing in mobile networks using the method of obtaining the route from the Top Level Mobile Router (TLMR) to the destination Mobile Network Node (MNN). The solutions for end-to-end routing include source routing, Table Driven Forwarding (TDF), and Route Request Broadcast (RRB). From the results of the simulations, it was shown that RBU+RRB presents the best performances among the different solutions. Whe...
