Trusted Quality of Service Routing Protocol in Mobile Ad-hoc Networks

摘要

MANETs are distributed wireless networks with uncertain infrastructure. In MANETs, Quality of Service provisioning is the most exciting area. Establishing the route to the destination with trusted intermediate nodes in terms of quality parameters is the major task, because of node mobility and lack of central administration. In multi-constrained QoS provisioning, more than two QoS requirements are to be satisfied until the end of the application. A QoS protocol has to attain the equality among the preference of multiple QoS parameters. Defining the priorities among them is a difficult task in MANETS, which depends on dynamic network conditions. Some methods are proposed, where they used static weights to the quality parameters and not capable of adopting dynamic topology changes. The proposed Trusted QoS model (TQM) uses fuzzy inference mechanism to accomplish this task. It takes QoS parameters like Bandwidth, Energy, minimum delay, reliability and link expiry time as input variable to calculate trust value of a node. This paper assures that data transmission is done through trusted nodes only.
