Abstract
A mesh network, which enjoys high connectivity, is very fragile to destroying events. These events will destroy some parts of the network and affect the network performance for a long time. Therefore, devising fault-tolerant routing algorithms for mesh networks is significantly important. In this paper, we introduce a Software-Defined Networking-based (SDN-based) fault-tolerant routing algorithm for a mesh network according to one existing wormhole routing technique because the concepts of SDN-based routing introduced recently and early wormhole routing are similar. Particularly, unlike the latter, we need not to assume that states of all nodes are known in advance. Instead, via the centralized management of the SDN controller, we propose a procedure to find the states of all nodes in flight. Moreover, with the management of OpenFlow flow tables, the implementation complexity of the routing algorithm can be simplified. Finally, we perform some simulation experiments to demonstrate the fault-tolerant capability of our SDN-based routing protocol.
