1. INTRODUCTION
Wireless networks have been gaining popularity in recent years for many reasons. Perhaps the most important of which is the innovative approach concerning the design of the wireless processors. Nowadays, we can see them integrated within compact electronic equipments like Pocket PCs. Another reason is the availability of those chips at cheap prices. An example is Intel's CMOS system, which is currently being manufactured and supports 802.11 b and g, as well as the next generation 802.11n wireless networks, and hence this is an indication that wireless networks will keep on gaining even more popularity in the near future. Another promising technology is Intel's WIMAX, a technology which will boost the popular VOIP. This popularity of wireless technology yields to that of wireless mobile ad-hoc networks.
