Abstract

In situations, when energy efficiency is crucial due the limited battery capacity and in noisy environment utilising spacial distribution is proven to be highly beneficial. Cooperative network strategies are based on this assumption. After introducing the related works in the field this report describes our method of implementing and simulating decode-and-forward cooperative strategy in the presence of additive white Gaussian noise (AWGN) on the transmit channel and also aims to explain the fundamental definitions of signalling theory, that were essential in designing the simulation. It also serves as an introduction to cooperative network strategies, explaining the basic concepts of the field. A mathematical model of decode-and-forward is presented that based on code division multiple access (CDMA) channel access method. The study describes an implementation of a cooperative strategy in NS 2 simulator as a physical layer protocol. The implementation involves fundamental modifications in NS 2 simulator’s base classes.
