As wireless communication gains popularity, significant research has been devoted to supporting real-time transmission with stringent Quality of Service (QoS) requirements for wireless applications. At the same time, a wireless hybrid network that integrates a mobile wireless ad hoc network (MANET) and a wireless infrastructure network has been proven to be a better alternative for the next generation wireless networks. By directly adopting resource reservation-based QoS routing for MANETs, hybrids networks inherit invalid reservation and race condition problems in MANETs. How to guarantee the QoS in hybrid networks remains an open problem.
In this paper, we propose a QoS-Oriented Distributed routing protocol (QOD) to enhance the QoS support capability of hybrid networks. Taking advantage of fewer transmission hops and anycast transmission features of the hybrid networks, QOD transforms the packet routing problem to a resource scheduling problem. A QoS-Oriented Distributed Routing Protocol for Hybrid Wireless Networks
Existing approaches for providing guaranteed services in the infrastructure networks are based on two models: integrated services (IntServ) and differentiated service (DiffServ) [42]. IntServ is a stateful model that uses resource reservation for individual flow, and uses admission control and a scheduler to maintain the QoS of traffic flows. In contrast, DiffServ is a stateless model which uses coarsegrained class-based mechanism for traffic management a number of queuing scheduling algorithms. Reservation-based QoS routing protocols have been proposed for MANETs that create routes formed by nodes and links that reserve their resources to fulfill QoS requirements although these protocols can increase the QoS of the MANETs to a certain extent.
We propose a QoS-Oriented Distributed routing protocol (QOD). Usually, a hybrid network has widespread base stations.
