Analysis of the joint use of the proactive and reactive methods of the topology information dissemination in ad-hoc wireless networks

A number of routing protocols for wireless ad-hoc (self-organizing) networks selects routes according to the topology information obtained by the station. Hence, the method of these protocols used to disseminate topology information strongly affects the network performance. An unsuccessful choice of the method can lead to a large amount of traffic and the information obsolescence. These factors diminish the network performance and make it impossible to meet quality of service requirements in transmitting realtime multimedia data, which is a topical problem. The routing protocol combining the proactive and reactive methods of the topology information dissemination has been proposed. It is demonstrated that this protocol is efficient in a wide range of scenarios applied to the exchange of real-time multimedia data.
