Hybrid Wireless-Optical Broadband Access Network (WOBAN) is a combination of wireless and optical network to optimize the cost and performance of an access network. Wireless nodes collect traffic from end users and carry them to the optical part of a WOBAN using multiple hops accumulating delay at each wireless node. Moreover, the radio-capacity on each wireless link limits the capacity on each outgoing link from the node in a single-radio Wireless Mesh Network (WMN) of a WOBAN. Thus, delay and capacity limitation in the WMN of a WOBAN is a major bottleneck. The authors design a capacity and delay aware routing scheme, CaDAR, to minimize the delay and increase network support in the WMN of a WOBAN.
