The performance of an overlay Bluetooth and IEEE 802.11b (WiFi) network is considered in terms of packet latency, packet error rate and throughput, in the presence of a vertical handover procedure. The objective of the overlay network is to maximize the quality of service (QoS), giving to a mobile user the possibility to switch from a network to the other, with the so-called vertical handover. The vertical handover is activated by the crossing of thresholds determined according to the user’s profile, which comprises objective values for the main QoS parameters, such as the packet error rate and the packet delay. The performance of the network is evaluated taking into account the mutual Bluetooth–WiFi interference and showing the influence of the main parameters of the network and of the handover procedure.

Abstract
The performance of an overlay Bluetooth and IEEE 802.11b (WiFi) network is considered in terms of packet latency, packet error rate and throughput, in the presence of a vertical handover procedure. The objective of the overlay network is to maximize the quality of service (QoS), giving to a mobile user the possibility to switch from a network to the other, with the so-called vertical handover. The vertical handover is activated by the crossing of thresholds determined according to the user’s profile, which comprises objective values for the main QoS parameters, such as the packet error rate and the packet delay. The performance of the network is evaluated taking into account the mutual Bluetooth–WiFi interference and showing the influence of the main parameters of the network and of the handover procedure.
