  The performances of multimedia applications built on wireless systems depend
on bandwidth availability that might heavily affect the quality of service. The
IEEE 802.11 standards do not provide performed mechanism for bandwidth
management through data load distribution among different APs of the network.
Then, an AP can be heavily overloaded causing throughput degradation. Load
Balancing Algorithms (LBAs) was been considered as one of the attractive
solution to share the traffic through the available access points bandwidths.
However, applying the load balancing algorithm and shifting a mobile connection
from an access point to another without considering the received signal
strength indicator of the concerned APs might causes worst communication
performances. This paper is a contribution to check the performance's limits of
the LBA algorithm through experimental evaluation of communication metrics for
MPEG-4 video transmission over IEEE 802.11 network. Then, the paper focuses on
the proposition of a new LBA algorithm structure with the consideration of the
RSS level.
