The shortcomings of existing description logics in the representation of fuzzy knowledge and data types are analyzed and a kind of new fuzzy description logic named F-SHOIQ(G) is proposed in the paper. F-SHOIQ(G) can support not only the representation of fuzzy knowledge, but also the representation of fuzzy data information with customized fuzzy data types and customized fuzzy data type predicates. Firstly, the concept of fuzzy data type group and a general formalism of the representation of fuzzy data types are introduced. Then, based on the fuzzy data type group, the syntax, semantics of F-SHOIQ(G) and the components of its corresponding knowledge base are defined. Furthermore, the satisfiability reasoning algorithm of F-SHOIQ(G)-concept based on the fuzzy Tableaux is presented. Secondly, the traditional reasoning architecture in which the reasoning of Tableaux expansion rules and data type can be divided is adopted for the reasoning of F-SHOIQ(G). The corresponding fuzzy data type reasoner is designed. Finally, the decidability of the satisfiability reasoning problem of F-SHOIQ(G)-concept is proved. The representation and reasoning capabilities of F-SHOIQ(G) go beyond the fuzzy description logic FSHOIQ in the representation of data information. F-SHOIQ(G) lays a theoretical foundation for the representation and reasoning of fuzzy data information in the Semantic Web.

In mobile ad hoc networks, the unstable transport layer and inhibited amount of traffic being carried out by the network is owing to the high packet loss rates and frequent topological changes. It is essential that least available bandwidth and end-to-end latency along with congestion around a link are integrated in a QoS-based routing metric for MANETs. In this paper we develop a QoS-based, robust multipath routing (QRMR) protocol for mobile ad hoc networks to allot weights to individual links, depending on the metrics link quality, channel quality and end-to-end delay. The individual link weights are combined into a routing metric to validate the load balancing and interference between links using the same channel. Consequently, the traffic is balanced and the network capacity is improved as the weight value assists the routing protocol to evade routing traffic through congested area. Subsequently, the selection of the proportion of traffic to be routed to each neighbor is made to perform routing such that the weight of the node is a possible minimum. We illustrate the robustness of our protocol as it accomplishes increased packet delivery ratio with reduced latency, through simulation results.
