Abstract

The objective of the Hybrid Wireless Network with dedicated Relay Nodes (HWN*) architecture is to interface the Base Station (BS) Oriented Mobile Network (BSON) and the 802.fix based Mobile Ad hoc Wireless Network (MANET) so that one system can be utilised as an alternative radio access network for data transmissions, while the incorporation of Relay Nodes (RN) is to extend the communication coverage, optimise medium resource sharing, increase spatial reuse opportunity, stabilise MANET link and create more micro-cells. The HWN* keeps the existing cellular infrastructure and a Mobile Terminal (MT) can borrow radio resources from other cells via secure multi-hop RN relaying, where RNs are placed at pre-engineered locations. The main contribution of this work is the development of a HWN* infrastructure framework and related algorithms. The framework addresses the inter-network traffic handover management, cross layer routing, node mobility models, RN positioning algorithms, the HWN* system topology, the HWN* time duplex multiplexing link scheduling scheme and the ad hoc nodes clustering scheme for the HWN* MANET component to increase current communication system capacity, improve Quality of Service (QoS), and optimise transmission delay and packet delivery quality. The research also presents network self-optimisation & self-configuration strategies by applying computational intelligence techniques and autonomic computing.
