—In a wireless mesh network (WMN), the traffic is aggregated and forwarded towards the gateways. Strategically placing and connecting the gateways to the wired backbone is critical to the management and efficient operation of a WMN. In this paper, we address the problem of gateways placement, consisting in placing a minimum number of gateways such that(More)
In this paper, we argue that additional radios should be placed according to the distribution of traffic load in WMN. We show that the capacity of a WMN is constrained by the bottleneck collision domain; hence, placing an equal number of radios at all nodes is not necessary. Only collision domains that need to support higher traffic load should be given(More)
Call admission control is a key element for providing quality of service (QoS) in mobile wireless networks. Traditional admission control schemes only address call-level QoS guarantee because of the underlying circuit-based network architecture. In contrast, emerging wireless technologies such as 3G and 4G tend to be packet-switched rather than(More)
This paper proposes a novel call admission control scheme capable of providing a combination of call and packet level quality of service requirements in cellular packet networks. Specifically, we propose a distributed call admission control scheme called PFG, which maximizes the wireless channel utilization subject to a predetermined bound on the call(More)
