“…The load metric represents the occupation ratio of a BS. The load of a cellular network is usually computed through the received power and the interference level [18] whereas the load of a Wireless Local Area Network (WLAN) is simply computed through the number of users connected to an access point [7,8]. The load can be computed in different manners for different systems.…”

“…As such a comparison is the basis of any cross-system load balancing solution, having a same semantic of the load metric is mandatory. The existing load computation methods, which are based on the interference [18] or the throughput [19], do not allow the load variation anticipation prior to the situation where a user moves into/out of a cell. The estimation of future interference or throughput values is really challenging.…”

Abstract-The paper aims at improving the load balancing algorithm in wireless packet cellular networks and particularly in coordinated heterogeneous wireless packet networks. Our main contributions are two-fold. First, we introduce a new approach to compute the network load metric based on the radio link quality and scheduling information, which can be applied to any wireless packet system. This load metric hides the radio resources heterogeneity of different access technologies from the load balancer. Secondly, we propose a new practical load balancing algorithm which provides a more efficient way to manage the scarce radio resources. The proposed approach has been compared with different existing schemes and the results show the superiority of the proposed solution.
