“…When the number of networks in the same carrier-sensing range is large, it is difficult to express the carrier-sensing duration due to the simultaneous transmission. A potential approach for expressing that simultaneity is applying the airtime concept as in [9][10][11][12][13][14]. The airtime concept is useful for revealing the frame collisions due to hidden nodes and the carrier-sensing duration at each node [9][10][11][12].…”

Recently, we often see the environment where many one-to-one Wireless Local Area Networks (WLANs) exist in a small area. In this environment, the network throughput of certain WLAN reduces significantly because of the interference from other networks (i.e., inter-network interference). The inter-network interference is the effect of carrier-sensing activities when there are ongoing transmissions in neighbor networks. This paper presents analytical expressions using airtime concept, which newly take into account the inter-network interference, for network throughputs of WLANs. There are existing works that similarly address the WLAN’s carrier-sensing duration. However, they either consider a simple interference model or assume the simultaneous transmission time is negligible. Different from them, we consider the significant impact of simultaneous transmission. As a result, our analytical model can precisely express each network carrier-sensing duration by subtracting the simultaneous transmission time. More specifically, we have successfully obtained each network throughput by expressing frame-existence probabilities concerning each network’s End Device (ED). We also confirm the validity of the analysis by comparison with simulation. The analytical results and the simulation results agree well.

“…The bottom-up analysis concept has a potential to be extended to variety of wireless network modeling, for example, multi-hop networks and WLANs of IEEE 802.11 Enhanced DCF (EDCF) [28], WLANs in the heterogeneous conditions [15], and interference model among WLANs. Because the proposed model cannot cover the backoff-stage synchronization yet, which is also a problem we should address in the future.…”

This paper introduces an overview of throughput and delay analyses of IEEE 802.11 networks, mainly from authors' researches. In our opinion, the difficulty of wireless multihop network analysis comes from the network-dynamics multiplicity between uniformity and locality in spatiotemporal fields. From the background, the concept of "bottom-up analysis" was advocated, which is Network-layer modeling over MAC-layer one with respect to each node. Generalities of analytical expressions increase by applying the bottom-up analysis concept. Additionally, it is possible to express end-to-end delays by including the queuing theory in the bottom-up analysis concept. The validity of the obtained model is confirmed by comparisons with simulation results.

Mitigating Traffic Remapping Attacks in Autonomous Multihop Wireless Networks

Multi-hop wireless networks with autonomous nodes are susceptible to selfish traffic remapping attacks (TRAs). Nodes launching TRAs leverage the underlying channel access function to receive an unduly high quality of service (QoS) for packet flows traversing source-to-destination routes. TRAs are easy to execute, impossible to prevent, difficult to detect, and harmful to the QoS of honest nodes. Recognizing the need for providing QoS security, we use a novel network-oriented QoS metric to propose a self-enforcing game-theoretic mitigation approach. By switching between TRA and honest behavior, selfish nodes engage in a noncooperative multistage game in pursuit of high QoS. We analyze feasible node strategies and design a distributed signaling mechanism called DISTRESS, under which, given certain conditions, the game produces a desirable outcome: after an upper-bounded play time, honesty tends to become a selfish node's best reply behavior, while yielding acceptable QoS to most or all nodes. We verify these findings by Monte Carlo and ns-3 simulations of static and mobile nodes.
