Enhanced Distributed QoS Routing Algorithms in Wireless Networks

چکیده
One of the goals of a routing protocol is how to satisfy the Quality-of-Service requirements for every admitted connection and how to achieve the global efficiency in resource utilization. On the other hands, the main goal of QoS routing; is to find a network path with sufficient resources to satisfy certain constraints on metrics such as delay and bandwidth. Many unicast / multicast QoS routing algorithms have been proposed, they work with a variety of QoS requirements and resource constraints. Overall, they can be partitioned into three broad classes; source routing, distributed routing and hierarchy routing algorithms. This paper proposes a distributed QoS routing in wireless networks. It is based on one of the most popular unicast distributed routing algorithm, called Ticket-Based Probing algorithm. Some modifications have been added to improve its performance. A comparison study has been done to evaluate the developed algorithm with respect to the original TBP algorithm, and a hybrid algorithm called mixed algorithm.
