Abstract: Considering FACS algorithm can solve the problem that ACSM is not capable of describing weak strength maneuvering,an advanced adaptive filtering algorithm MFACS was introduced and on this basis a mobility prediction algorithm was raised,which was used in HELLO mechanism of GPSR creatively.Combining with a two hops adaptive beacon and relevant neighbor maintaining mechanism,according to whether adopt mobility prediction,two modified routing protocol GPSR-TAMP and GPSR-TA based on GPSR were derived to modify periodical beacon.NS2 simulation result demonstrates that with a better neighbor discovery mechanism,GPSR-TAMP outperforms GPSR-TA.
