Communication channel model simulated using Digital elevation maps and modified deterministic Loo model

Techniques for modeling and simulating channel conditions play an essentially role in understanding network protocol and application behavior. In this paper we will describe two ways of modeling communication channel. It will be method which uses information above real condition of environment in which the transmition take place and use them to compute channelmodel in contrast to methods based on empirical model of channel. Then information from real based simulation will be used to modify empirical model.
