Abstract: Local routing strategy based on Zone_Cut was put forward for network simulation. All nodes in topology were divided into three zones, including T Zone, LD Zone and HD Zone according to the property of the node. To reduce the storage space and search time of routing strategy, different storage and search mechanisms were adopted for different zones, which balanced the space and time of routing mechanism. Experimental results on PDNS show that Zone_Cut improves the comprehensive properties of routing strategy, compared with the MTree_Nix. Compared with MTree_Nix, it can reduce the simulation time and simulation space by about 18.08% and 51.23% respectively in low frequency, while in high frequency, it can reduce the simulation time and simulation space by about 55.29% and 74.4% respectively.
