This paper presents a Per-Packet Dynamic Channel Allocation scheme for multiple channels MAC protocols in a infra-structured wireless network. The proposed MAC protocols implicitly assume a static channel allocation for each Access Point in the network. Our scheme assigns the requested channels to the APs in a dynamic mode.Furthermore resources allocation is performed in an original Per-Packet way, instead of classical per-call methods. Performances of this idea, in terms of packets dropping probability and average number of used channels for non dropped activity, are analyzed in a simulative way. The results show a higher system efficiency in the resource use of the proposed algorithm in comparison to the static channel allocation schemes.

Abstract
This paper presents a Per-Packet Dynamic Channel Allocation scheme for multiple channels MAC protocols in a infra-structured wireless network. The proposed MAC protocols implicitly assume a static channel allocation for each Access Point in the network. Our scheme assigns the requested channels to the APs in a dynamic mode.Furthermore resources allocation is performed in an original Per-Packet way, instead of classical per-call methods. Performances of this idea, in terms of packets dropping probability and average number of used channels for non dropped activity, are analyzed in a simulative way. The results show a higher system efficiency in the resource use of the proposed algorithm in comparison to the static channel allocation schemes.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
