Abstract

In mobile wireless networks, path breakage happens frequently due to the movement of mobile nodes, node failure, channel fading and shadowing. It is challenging to combat path breakage at the cost of minimum control overhead, while adapting to topological changes rapidly. Due to the Wireless Broadcast Advantage, all nodes inside the transmission range of the transmitting node may receive the packet. Inherently, those nodes serve as cooperative caching and backup nodes if the intended receiver fails to receive the packet. In distributed robust routing, presented here, nodes work cooperatively to enhance the robustness of routing against path failure. Our simulation results show that robust routing improves robustness in mobile wireless sensor networks while achieving energy efficiency.
