[Bug Report]

-----------------------------
Category:  Validation Failure
Package:   ns ns-2.29
OS:        Red Hat 9
Environment Variables:
LD_LIBRARY_PATH=
TCL_LIBRARY=
TK_LIBRARY=

Description:

Description of Problem:

While using a vertical handover scenario i receive a throughput more than the technology capacity. i.e at UMTS i receive 80 Mbps which is impossible.


How Easily Reproducible:

Every time i can receive the same datarate what i am going to transmitt.

Steps to Reproduce:

1. Using MIH Patch "ns-nist-mob" developed ny NIST in ns-allinone-2.29.
2. Running Vertical Handover Scenario i.e UMTS-to-WLAN handover. 
3. Send a traffic having datarate of 80 Mbps and also receive the same datarate of 80 Mbps at both the technologies UMTS and WLAN respectively.


Actual Results:

It gives Sendrate = Receive rate and accept every datarate i am going to transmitt. i.e it can transmitt 2 Gbps which is impossible. 

Expected Results:

At UMTS it should transmitt a maximum rate of 800 Kbps to 1 Mbps.
At WLAN it should transmitt a maximum rate of 11 Mbps to 54 Mbps.
at WiMAX it should transmitt a maximum rate of 11 Mbps to 72 Mbps.

Additional Information:

 1. Install ns-allinone-2.29 simulator on Red Hat 9.
 2. Configure a Patch "ns-2.29" developed by NIST for Seamless handover.
 3. Find throughput of running scenario UMTS-to-WLAN handover.
