A propos de l'équipe

Context The tremendous growing needs of radio resources associated with the recent explosion of wireless-based services led the standardization industry to propose a large number of standards driven by different groups from the IEEE (802 family), ETSI (GSM), 3GPP (3G, 4G) or the Internet Society (IETF standards). Roughly speaking, the upper layers of the OSI model, from layer 3 (network) up to layer 7 (application) are nowadays mostly driven by the proposals of the IETF, while the IEEE802 family offers the major contributions at layers 1 and 2 (except for cellular networks) and represents the basis of numerous famous commercially available technologies such as WiFi (802.11), Wimax (802.16), Bluetooth or Zigbee (802.15.4),... So far, all standards are developped with a bottom-up approach: physical (PHY) and radio link (RL) layers are firstly defined (see the IEEE 802 family for instance) and provide specific capacity and multiplexing capabilities. Then, the networking (NET) layer is der
