AODV routing protocol to improve the local repair mechanism
; P × (1 a P) + T2 × P2] T2 × P-P × (1 a P) × (T2 A T1) (4) by (1) and P <1 we can see, (4) ≤ 0 that TAORTI ≤ TA () DV, when node C node Dest equation was established. When the node from the node C than node Dest eight more recent, then TAORTI more than TAODV small. This also proved that the improved routing algorithm pathfinding AORTI time than the traditional A () DV shorter, and the node (node A than node Dest closer distance, the effect is more obvious. On the routing protocol overhead, due to improved AORTI agreement The purpose of increase of two-hop nodes under the RREQ, and the routing table stored under the two-hop node address, and two-hop node address is valid to judge, so the route will rise off mountain road than traditional AODV algorithm to dogs. 3 Conclusion In this paper a detailed analysis of a typical Adhoc network routing protocols A0DV the local repair mechanism, and on this basis, the proposed species to improve thinking, as opposed to [2] words, increase the likelihood of a successful double r, and the effective to shorten the route repair, asked for understanding of Adhoc network routing mechanisms and improve the system throughput, reduce latency, improve network OoSl3I students can have some positive meaning, the next step in the theoretical evaluation of the work Based on the experimental simulation to further improve the algorithm performance analysis.
