With the development of IEEE 802.11 MAC (Medium Access Control) protocols, efficient utilization of wireless local area networks (WLANs) has become a very important issue. In typical IEEE 802.11 networks, the association between mobile users (MUs) and access point (AP) is based on the signal strength information. As a result, it often results in the(More)
For the mobile users (MUs) installed with IEEE 802.11 wireless adapters, the default best-signal-strength-based access point (AP) selection is limited since it does not consider fairness and multi-rate issues. In this paper, we propose a distributed AP selection algorithm for newly joining MU and already associated MUs to be adaptive to their joining order(More)
In this paper, we propose a new distributed QoS routing algorithm LMLAR (local multicast location-aided roztting)algorithtn. The key idea of the proposed algorithm is to urilize the local multicast mechanism and the location information to select the route. The silnulation shows that the LMLAR algorithm cun acquire the higher routing success ratio and the(More)
In this paper, we address access point (AP) selection for mobile nodes (MNs) in IEEE 802.11 wireless mesh network (WMN). Unlike the hotspot-based AP model, the service capacity of mesh AP in WMN is limited by the wireless connection to gateway AP and varies with the hop distance to the gateway AP. Using the multi-rate throughput model of [1], we formulate(More)
In order to utilize network resources efficiently and reduce regional congestion, associating mobile stations (MSs) with proper base stations (BSs) is of crucial importance in wireless cellular networks. There have been several load-aware proposals in literature, where most are classified into so-called closed-form approaches. In such approaches, each MS(More)
In this paper, we will study an broadcast protocol based on prioritization for delay-tolerant networks (DTNs). Considering the feature of the DTNs where there may be rare stable links, we propose an application-oriented broadcast (AOB) protocol built atop “bundle layer” in DTNs, which adjusts the forwarding probability for different types of traffic(More)
