The aim of this thesis is to investigate the traffic patterns in the mobile data
networks. In this work, a simple Cellular Digital Packet Data (CDPD) network
was modeled in order to be used in simulations. For the purpose of using in the
CDPD model, a synthetic bursty traffic model was produced and using different
traffic patterns some performance investigations were made in CDPD network.
During the whole work, OPNET simulation tool was used.
The CDPD network modeled by OPNET simulation tool was compared
with a CDPD model described in the literature and the differences were shown.
The new model has some new features: 1) Burst transmission of MAC blocks. 2)
Exponential backoff. 3) New packet structures. 4) Frame segmentation and
encapsulation into MAC layer frames.
Using OPNET, a traffic having higher level of burstiness was produced and
applied to the CDPD network model. Under the bursty traffic, some CDPD
performance parameters were collected and according to the collected results
some suggestions were given.
