基于VANETs下的决策树多副本机会路由协议
Multiple copies of VANETs based on decision-tree for opportunistic routing protocol
摘要
Abstract
In order to effectively forward and deliver the messages in the Vehicle Ad Hoc Networks (VANETs),the selec-tion of routing node is the key issue in the Vehicle Networks in the case of fixed node buffer and limited number of message copy.Therefore,in this paper,we propose an effective opportunistic routing protocol for the multiple copies of VANETs based on the decision tree theory (D-Tree).The proposed scheme takes the intermediate node’s transmission and connec-tion as the set of multiple attributes,and then we can obtain a rule of message forwarding based on the attributes and D-Tree.Furthermore,we can combining the advantages of multiple copies routing scheme and adopting the storage-carry-forwarding of opportunistic routing to deliver the messages.Simulation results confirm that our proposed D-Tree network model,decision rule procedure and calculating method improve the success rate of delivery compared with the conventional Bubble routing algorithm by 1 0% under the case of density environment.The proposed scheme also demonstrates better performance in delivery delay.关键词
