NICTA is developing networking technologies for a reliable, low-latency, and secure communication platform for traffic control systems. Wireless mesh networks offer a cost-effective solution which is easily deployable and expand-able to new nodes and new applications. Reliability and timely delivery of critical data will be achieved through innovative routing algorithms that efficiently exploit the many redundant wireless links between nodes. The routing algorithms incorporate robustness mechanisms to protect the network from collapsing should the wireless nodes be compromised. Techniques for automatic fault prediction, detection, and recovery will augment the wireless mesh network with a self-healing capability that will in turn reduce maintenance effort. Extensive on-street test-beds developed across selected areas of Sydney will be used to validate and demonstrate the technologies. The pilot test-bed, deployed over seven Sydney intersections is being used to measure and analyse long term link characteristics. Simulation studies based on initial versions of multi-path routing and automatic fault detection algorithms are underway. In simulation experiments, these algorithms show resilience against some failures and known mis-behaviours. |
