Recently, Mobile Ad Hoc Networks (MANETs) have enjoyed a dramatic rise in popularity as potential solutions to connectivity in environments where telecommunication infrastructure is not available. Traditionally, MANETs are assumed to be stand-alone networks which do not require assistance from fixed network infrastructure (e.g. a backbone network). Based on this assumption, routing protocols for MANETs have been designed to work in stand-alone mode. However, throughput and coverage requirements of future 4G all-IP systems may require integration of MANETs into these systems to enhance the flexibility and pervasiveness of the networks. The coverage of existing infrastructure networks (wireless LAN hot-spots of 3G networks) can be effectively extended by the relaying communications via ad hot network nodes (wireless routers). Also, the limited services available within MANET can be extended to a wider range through connecting of the MANET to the Internet infrastructure. To achieve this, effective solutions are needed to many existing challenges in integrating MANETs with the Internet. / In this thesis, we propose solutions to three major challenges of interconnecting MANETs with the Internet. The underlying research problems can be listed as follows: Architecture options for integrating Mobile IP-based MANETs to the Internet via multiple gateways; The Internet extensions to reactive ad hoc routing protocols; Schemes for gateway discovery / Handoff in MANETs. / Thesis (PhDTelecommunications)--University of South Australia, 2007.
