The following remarks could be extracted from the above table:

1. Acceptable FTP response time values which were below the required

threshold.

2. DSR protocol proved its effectiveness in terms of its: low Route

discovery time, low packet dropping rate, low bandwidth utilization.

3. The higher layer data traffic (in bits/sec) dropped by the WLAN MAC

due to consistently failing retransmissions. The result reported that the

number of the higher layer packets that were dropped were half in

some nodes, and less than half of the wireless (LAN.load).
