In recent years, the rapidly expanding area of mobile and wireless computing applications was definitely redefined the concept of network security. Even though that wireless had opened a new and exiting world with its advancing technology it is no doubt that it is popularity is on the rise. However, the biggest concern with either wireless or mobile computing applications in security. It can no longer be effective in the traditional way of securing networks with the use of firewalls and even with the use of stronger encryption algorithm keys. The need to develop and research for new structures and methods to protect and define the wireless networks and the mobile computing applications is becoming more and more evident. In this report, we will conduct an in-depth analysis of the weaknesses of the wireless networks and hence proved why the use of an intrusion detection system is of great importance in securing the backbone of mobile computing field. This would also involve detecting anomalies in the mobile ad-hoc network including inconsistencies in the routing tables and activities on other layers.
