A Throughput Model Based on Prior Link Probability for Fiber Aided Wireless Mesh Networks

Wireless mesh networks (WMNs) are thought by many as one of the most potential networking technologies for next generation wireless networks. However, WMNs´ performance is vulnerable to the interference in the environment. In order to get higher bandwidth and data transmission rate, fiber links are used to assist the communication in WMNs. The new network is called fiber aided wireless mesh networks (FAWMNs). There are two kinds of nodes in FAWMNs: those which only support wireless link and those which simultaneously support wireless link and fiber link. Correspondingly, there are two kinds of manners for packets transmission in FAWMNs: (i) several single wireless links manner; (ii) the wireless-fiber- wireless link manner. These make the packet transmission have multiple path choices. In this paper, a throughput model based on prior link probability for FAWMNs is proposed. The results demonstrate that the introduction of fiber links can bring some positive changes on the distribution of links and a noticeable promotion for the throughput of the node in FAWMNs.
