“…Based on these parameters and the network state, the QAP makes an admission decision and sends back the results in the ' ADDTS.response' frame. Note that the network operators are free to implement their own algorithms of admission decision because the IEEE 802.11e only describes the signaling frame format for admission control [12]. Xiao and Li [13] proposed a distributed asynchronous cooperation (DAC) protocol.…”

“…In [12], Lin and Wong proposed a centralized admission control mechanism model based on the theory of conflict graph. The authors used a contention graph to model the contention situation in a multihop network, and they presented an analytical model to estimate the capacity for each maximal clique in the contention graph.…”

“…As our detailed survey showed, some AC models (e.g., [12], CMC, IFCAC, StAC, DACME, [28]) are decoupled from routing schemes; they suppose that a route for a requesting flow has already been discovered, and their main task is to evaluate the route's fitness for supporting the flow's requirements. Thus, they are totally free from the routing scheme deployed in the network.…”

“…Note that almost all earlier routing-coupled and routing-decoupled AC models are based on DCF, for example, IFCAC, PAC, HRAC, StAC, CACP, ACSCQS, MACMAN, AAC, etc. On the other hand, the AC models which are decoupled from the MAC layer (e.g., RFAR, SWAN, FuzzyQoS, [12,28]) can utilize only information of the network layer; this leads to a simpler interaction with different MAC technologies without need to a complex cross-layer design, but at the expense of false admission issue ( Table 2).…”

“…While some models, like INORA, allow multiple routes to cooperatively support the session but only under a simplified interference cases, other models (e.g., MARIA, CACP) have implemented a routing scheme that explicitly incorporates an interference model based on local maximal clique constraints in the route discovery process. Some models (e.g., [12,47]) dealing with the interference issue use the conflict graph which is highly complex; even for a small network, the number of interference constraints can be very big. Note also that some earlier works (e.g., HRAC, DACME, INSIGNIA, INORA) ignored the impact of intra-route contention on a flow's capacity requirement prior to admission decision.…”

Wireless mobile ad hoc networks (MANETs) have emerged as a key technology for next-generation wireless networking. Because of their advantages over other wireless networks, MANETs are undergoing rapid progress and inspiring numerous applications. However, many technical issues are still facing the deployment of this technology, and one of the most challenging aspects is the quality of service (QoS) provisioning for multimedia real-time applications. MANETs are expected to offer a diverse range of services to support real-time traffic and conventional data in an integrated fashion. Because of the diversified QoS requirements of these services, QoS models are needed for an efficient usage of network resources. One of the most crucial mechanisms for providing QoS support is admission control (AC). AC has the task of estimating the state of network's resources and thereby to decide which application data flows can be admitted without promising more resources than are available and thus violating previously made guarantees. In order to provide a better understanding of the AC research challenges in MANETs, this paper presents a detailed investigation of current state-of-the-art AC models in ad hoc networks. A brief outline of the admission function, feedback to route failures, as well as the advantages and drawbacks of each discussed model are given.

This paper analyzes a large-scale dataset of real-world Wi-Fi operating networks, collected from more than 9,000 access points (APs) for 1 year. The APs are distributed among more than 1,200 educational centers in the context of a nation-wide one-to-one computing program, being most of them primary and secondary schools. The data corresponds to RSSI measurements between APs used to build the conflict graphs for each school Wi-Fi network. We propose a simple embedding for the Wi-Fi network conflict graphs based on classical graph features, which proves to be useful to analyze the behavior of the wireless networks, showing a high discrimination power among the different school networks. Moreover, we discuss some practical applications of the embedding. In particular, it enables to study the Wi-Fi network dynamics at each school, analyzing the conflict graphs temporal variations through clustering techniques. The presented methodology allows us to successfully separate the most stable scenarios from those with more significant variability, which therefore require more technical resources to optimize the network. Besides, we also compared the behaviour of the Wi-Fi networks of the different schools, which enable us to reuse the optimal configuration found for one school in all those sites that have similar conflict graph patterns.
