Zone routing protocol based on hierarchical structure
HU Yu-q · Journal of Yanshan University · 2014
The Zone Routing Protocol(ZRP) of ad hoc networks combines the characteristics of active and reactive routing protocols, to make a compromise between routing delay and communication overhead, and showed good performance. However,ZRP protocol also has drawbacks like zones in a high degree of overlap and low scalability. In order to solve the disadvantage of a high degree of overlap of the zones, this paper uses the concept of clusters in the hierarchical network structure to replace the zone in ZRP. Partition process takes place in the senior layer of the hierarchical network structure, and proposed a zone routing protocol based on hierarchical structure, called CB-ZRP(Clustering-Based ZRP). Through simulation on ns-2 platform, the properties are analyzed in the three aspects of average end-to-end delay, packet delivery ratio and routing load. Routing load of CB-ZRP is about reduced 25 percents of ZRP.
