1、Wireless communications of today is moving from cellular networks towards more distributed，self-configuring ad hoc oriented networks. Wireless had a huge growth over the passing years，first with cellular phones(more than

2、 one billon users) and then wi-fi.
　　 The integration of mobile ad hoc networks into cellular wireless networks is with huge interest today. Due to the multiple hop functionalities offer by MANETs which give many adv

3、antages to cellular networks such as increase coverage，data rates，QoS performance in terms of call blocking probability，bit error rate，as well as QoS fairness for different users.The routing problems in heterogeneous net

4、work become popular researches nowadays. The heterogeneous network is the integration of ad hoc network in a cellular network.
　　 This thesis is about evaluation of the performance of some ad hoc routing protocols fo
