Abstract
System and method of ad hoc on-demand routing by virtue of central control. A central controller of a network can communicate directly with a route-requesting network device regarding discovery of a data transmission path and perform route computation. A source network device may query the central controller with a unicast route request. In response, the central controller can identify a feasible route based on the topology information of the network. The central controller may also receive a broadcast route request along with other network nodes. As a result, the source device can be offered to select from two resultant routes, one provided by the central controller in a centralized manner and the other provided by the destination device. Further, the central controller can be used specifically for computation of constrained routes by incorporating global constraints. The central controller may be a software defined network (SDN) controller.
