车载传感网中基于群特性的MaxProp路由协议改进
IMPROVEMENT OF MAXPROP ROUTING PROTOCOL BASED ON GROUP FEATURES IN VSNS
摘要
Abstract
The main problem of information transmission in VSNs is intermittent network connectivity and highly dynamic topology.In the past we often used the idea of forwarding the design of routing protocols to solve this problem.However, the existing opportunistic routing protocol ignores the features of some nodes in the network with group mobility, which leads to a sharp decrease of the performance of the protocol in the group moving scene.To solve this problem, a MaxProp routing protocol based on group features is proposed by improving the maximum probability of encounter.This protocol increases the message forwarding opportunities by increasing the probability of encounter between the nodes in the group and the external nodes indirectly through the inter-group message diffusion by using the excellent connectivity among the members of the group.In the ONE simulation platform, compared with other several classical opportunistic routing protocols, the improved MaxProp routing protocol has a significant improvement in message transmission success rate and network overhead ratio.关键词
