OLSR Optimisation for Lightweight MANET Internet Integration

MANET technology can complement other network technologies when integrated with them. This integration reduces communication and deployment costs and provides additional services for MANET. The integration of heterogeneous networks unavoidably raises significant issues. Gateways are employed to overcome the incompatibilities between different communication architectures. This paper proposes a system based on optimised link state routing (OLSR) to integrate a MANET with the wider Internet. The proposed system solves the micro-mobility issue by eliminating the process of mobile node registration with a specific gateway. Hence, no independent gateway discovery procedure is required. Instead, the proposed system optimises an OLSR routing mechanism to disseminate gateway information. The proposed system is evaluated using a network simulator to investigate its behaviour under different network settings.
