All, I ran simulations for 80 nodes, to add to my previous GTNetS simulation results for 20, 40, and 60 nodes. I used the same code that I used before. INRIA's protocol used MPR-based LSA reduction and MPR-based adjacency reduction (but retransmitted LSAs were not multicast). MDR used 1-connected adjacencies and min-cost LSAs. The same trend continued, with INRIA generating 15 times as much DD overhead as MDR, and 5 times as much total overhead as MDR. LS Ack overhead (not shown below) was 204.24 kbps for INRIA and 75.14 kbps for MDR. Note that using multicast retransmitted LSAs will not affect DD overhead, and may increase LS Ack overhead (since every adjacent neighbor must Ack each multicast LSA). Parameters were given with my previous results. Summary of results: MDR 20 nodes 40 nodes 60 nodes 80 nodes --- -------- -------- -------- -------- Total Overhead (kbps) 21.52 79.08 164.32 271.00 LSU overhead (kbps) 5.21 18.05 33.67 50.56 DD overhead (kbps) 4.08 18.54 36.28 60.88 Adjacencies/node 3.30 3.02 2.88 2.84 Adj changes/node/sec 0.04 0.04 0.04 0.04 Delivery ratio 0.966 0.951 0.953 0.949 INRIA 20 nodes 40 nodes 60 nodes 80 nodes ----- -------- -------- -------- -------- Total Overhead (kbps) 48.20 234.12 588.43 1357.45 (5xMDR) LSU overhead (kbps) 10.32 40.08 72.33 127.56 DD overhead (kbps) 18.40 119.92 352.89 934.31 (15xMDR) Adjacencies/node 8.58 15.93 21.93 25.12 Adj changes/node/sec 0.15 0.27 0.36 0.53 (13xMDR) Delivery ratio 0.918 0.924 0.920 0.912 Richard _______________________________________________ Ospf-manet mailing list Ospf-manet@ietf.org https://www1.ietf.org/mailman/listinfo/ospf-manet
