In this paper, we propose a new scheme for aggregating access points backhaul bandwidth resources in wireless local area networks. We consider a setting with several access points, some with excess backhaul capacity, and others in shortage of it, and propose a symmetric approach wherein the distribution of resources is managed between providing and(More)
We conduct in this work a comparative study between a greedy versus limited proposals for resource aggregation in the backhaul of wireless local area networks. We consider a setting with several access points, some with excess backhaul capacity (providers), and others in shortage of it (beneficiaries) and investigate two approaches for the distribution of(More)
During the handover, quality of service (QoS) in LTEA systems poses quite a challenge especially for real-time services. In high speed mobility, the handover procedure becomes more delicate as it occurs more frequently in a time basis scale. In fact, a currently used resource in a “source node” could be not available in the “target(More)
Wireless communications markets present rapidly changing technology, evolving customer demands, and the emergence of new products and services. Within spectral limitations, wireless standards end up competing for optimal network performance and better client satisfaction, especially for residential scenarios and hotspots. In actual wireless networks, the(More)
In this paper, we propose a new approach for dynamic frame aggregation at Medium Access Control layer (MAC) in wireless local area network. We considered an IEEE 802.11n infrastructure mode network, and a VoIP communications' context. Among diverse suggested schemes of frame aggregation, we opted for the MAC Protocol Data Unit (MPDU) to be the basic unit(More)
