Opportunity Forwarding Method Based on Time and Space Prediction in Ad Hoc Networks
Feng Yang, Di Liu · International Conference on Control Engineering and Communication Technology · 2013
In Ad Hoc networks, the routing table needs frequent reconstruction due to quick-changed topology caused by the node's movements and computing limitations. The reliability and efficiency of packet forwarding will be affected since it is quite difficult to execute data forwarding algorithm on the original topology. With knowledge of social networks and behavior rules, first construct a connected sub-graph, and then build up a time &space-predicting forwarding model by analyzing and predicting the node's contact time, contact time interval and spatial location as well. Stimulation results show that this model can effectively predicting and establish forwarding route, and it has greater improvement, compared with the existing model, in packet forwarding success rate, end-to-end performance on the average delay and the average routing overhead.
