MISCELLANEOUS LINKS 

1.Wanna learn about the ATM Specs? Go to the ATM Forum

2. Some stuff about Ad Hoc Networks

                      IETF's MANET page -

          Links to a couple of Routing Algo's  -

               - TORA

               - AODV

3.Mobile IP-A tutorial   by Charles Perkins

4. CDMA and W-CDMA tutorial

5.Convolutional Codes and Viterbi Decoding tutorial- Its pretty good..... with lots of references and practical applications  & specs.

6. A Few Simulators:

      *GLOMOSIM- A scalable mobile network simulator developed at UCLA. GLOMOSIM has the following routing protocols built into it : IP with AODV, Bellman-Ford, DSR, Fisheye, LAR scheme 1, ODMRP, WRP. At the MAC  layer it has CSMA, IEEE 802.11 and MACA built into it.(Free download for researchers)

      *NS-2 - The most popular software for simulating routing, multi-cast and TCP protocols over wired/wireless networks. (free download for researchers)

      *OPNET - The software used by almost all commercial organizations for network simulations.  (its not free guys, but students can apply for a 6 month trial license)

7. White papers: I found a cool site with tons of white papers on Communications and Networking . Click  to go to ITpapers.com
