On Applicability of the Assurance-Oriented Route-Split Routing Method for MANETs with Varying Node Density

Abstract

Assurance network technologies are necessary to produce trustworthy terminals or infrastructure service applications for potentially large-scale networks such as in the Internet-of-Things. In large-scale network systems, not only the size of the network will become larger but also the density will vary in the network. Mobile ad hoc networks (MANETs) could be the future of networks. In the future, the size of networks will become larger. In real situations, nodes are not uniformly distributed in networks. The difference in node density will be greater in large-scale networks. When flooding is conducted in a dense area, network congestion occurs and nodes cannot communicate with each other. As proposed in paper [1], Route-Split Routing (RSR) can communicate with a higher throughput than theAd hoc On-demand Distance Vector (AODV) method in large MANETs. Along with the assurance network design principle, RSR splits its route by configuring Sub-route Management Nodes (SMNs) using a constant value called the SMN interval. In large MANETs, nodes are not distributed evenly. Thus, routing protocols for large MANETs must take into consideration that its route will pass through sparse areas and dense areas. In this paper, we propose a new routing method based on RSR for large
