In ad hoc networks, ZRP (Zone Routing Protocol) combines a proactive routing protocol with an on-demand routing protocol. Proactive routing is adopted in the intra-zone, and on-demand routing is adopted in the inter-zone. During the process of the inter-zone routing maintenance in ZRP, there is a low reliability problem. So NHRP (New Hybrid Routing Protocol) was proposed, and the protocol reliability relationship between ZRP and NHRP was demonstrated by a comparative analysis on route reliabilities of ZRP and NHRP. The theoretical analysis shows that NHRP takes higher reliability than ZRP.
The research progress of the typical hybrid routing protocol (ZRP, Zone Routing Protocol) in ad hoc networks is analyzed, which includes the analysis on ZRP and the analysis on ZRP related research. This work can provide a reference of basic theory research of ZRP for experts and scholars. And it will get ready for the further research work in the future.
