摘要
Along with the emergence of real-time multi-media,interactive service,real-time voice and other services calling for high quality of service,there should be a good network to support those services.Most present route algo- rithms with computational complexity hardly consider the restriction of node energy,so it degrades the whole capabil- ity of network.Bandwidth guarantee is one of the most crucial factors in real-time application,and this paper brings forward a distributed on-demand QoS routing protocol based on energy and bandwidth requirement.This QoS routing protocol makes use of bandwidth calculation algorithm and analyzes its route mechanism.The simulation results veri- fy its validity.The QoS routing protocol improves the packet delivery fraction and average end-to-end delay,prolongs the network lifetime,enhances the network performance and satisfies the route requirement for ad hoc networks.
Along with the emergence of real-time multi-media, interactive service, real-time voice and other services calling for high quality of service, there should be a good network to support those services. Most present route algorithms with computational complexity hardly consider the restriction of node energy, so it degrades the whole capability of network. Bandwidth guarantee is one of the most crucial factors in real-time application, and this paper brings forward a distributed on-demand QoS routing protocol based on energy and bandwidth requirement. This QoS routing protocol makes use of bandwidth calculation algorithm and analyzes its route mechanism. The simulation results verify its validity. The QoS routing protocol improves the packet delivery fraction and average end-to-end delay, prolongs the network lifetime, enhances the network performance and satisfies the route requirement for ad hoc networks.
