A Mobility Management and Routing Protocol Using Tree Architecture for Internet Connectivity of Mobile Ad Hoc Networks

We propose a tree-based routing protocol (TBRP) with node mobility management technique for integrated mobile ad hoc and infrastructure networks. A suite of network management protocols build and maintain a network architecture in the form of small-sized trees, each starting from a node that can directly communicate with a gateway. Each node in a tree keeps track of information for its descendent nodes. A new node registers with a foreign agent along a tree path without resorting to an inefficient flooding. We also devise an efficient routing protocol that exploits tree information where route discovery does not use a flooding, either. We examined the proposed protocol for its applicability and got a promising result, even with high network traffic.
