Abstract

The present chapter contains a thorough investigation of Quality of Service, Energy Conservation and mobility in 802.11 and 802.16 standards. Interest on these two technologies arises from the fact that they are designed to cooperate offering wireless access capabilities in Next Generation Networks (NGNs). Under NGN Wireless architectures, key challenges must be taken into account: (a) Broadband technologies are based on QoS Enabled Telecommunication Services; (b) Mobile devices are battery limited. In fact, how to prolong the life time of a mobile device and minimize power usage is a very important design issue; (c) Wireless operation means that the user is expected to roam freely, which must also be taken into account. The dependability of NGN operation is obviously depended on these three features.
