CE_QoS Routing Algorithm for Ad Hoc Networks

In an ad hoc network, QoS support is one of the major concerns. Because of the constant changes of available link state and bandwidth information, the limited node power, and the dynamic network topology, it is difficult for routing algorithms to satisfy the QoS requirements of many applications. In recent study, we proposed CEQoS routing algorithm for ad hoc networks. Taking bandwidth as the QoS parameter, CEQoS uses a node credit model to evaluate the link stability, and uses an energy function to estimate the node power situation. Based on these strategies, CEQoS can support QoS requirement and has better QoS routing performance. In this paper, we give an example to show how CEQoS works.
