This test again ran into major problems with the memory leak due to nodes randomly failing, not

allowing for any consistent results and causing inaccurate data.

Results and Analysis

The section will outline and analyze the results acquired from testing. Unfortunately only partial

data will be presented due to the memory leak in the Madwifi driver already mentioned. The

DSDVRouteTable data in Appendix D shows an Internet connection through five hops could be

competed and the network was successful. Data collected from the Number of hops test looking

to Table 8-2 were inconclusive. For the TCP test, throughput did reduce significantly between

hop 1 and hop 3 but where hop 2 increased slightly. In contrary, the RTT decreased as the number

of hops increased which was not an expected result. This can be attributed again to the lack of

stability in the network due to memory leak in the Madwifi driver. The UDP test showed very

little correlation between any of the data points. In addition to the previously mentioned problem,

these packets were unguided and did not have any control protocol to prevent dropped packets or

initiate recovery, which may have attributed to the inaccuracies.

From the tests above it was shown that a network connection was successful under low load

situations for short periods of time. Network instability was the major factor during testing load

situations causing data to be inaccurate.
