“…In this case, the jammer can be detected by the IDS and reduces the effect of its attack. The random RTS validation is proposed by Ashikur [7] to alleviate the impact of this attack. If the attacker chooses the false RTS attack, it needs to spoof the source address in the RTS packet sent by the victim node's address, in order to escape the punishment reaction of the IDS.…”

Abstract-In this paper, we show new smart attacks which were not dealt with in the solutions proposed recently. We focus on the Medium Access Control (MAC), particularly the IEEE 802.11 and we study some hidden vulnerabilities based on the control packets. The malicious nodes can exploit these vulnerabilities to reduce the network's performance, to disturb the monitoring, routing processes and to escape the Intrusion Detection System (IDS). Furthermore, we show how vulnerabilities can be exploited and how these attacks can be implemented by the attacker. Moreover, attacks' algorithms and the security analysis are presented. We investigate on the effect of these attacks with the simulations and the experimentations. The simulations' results and their analysis illustrate the negative impact of these attacks on the network. In addition, the experimentation results demonstrate the feasibility to real exploitation of these attacks and they confirm the simulation's results.

“…Node B is within the transmission range of nodes A and C, whereas node C is located outside the transmission range of node A. In a situation like this, node C cannot detect transmission from node A and consequently it can indirectly interfere with node B's reception of A's transmission [19].…”

Abstract. In wireless networks, available bandwidth estimation is challenging because wireless channels are used by multiple users or applications concurrently. In this study, we propose a passive measurement scheme to estimate the available bandwidth in 802.12 wireless networks based on the combination and modification of two existing schemes, Distributed Lagrange Interpolation Based Available Bandwidth Estimation (DLI-ABE) and Accurate Passive Bandwidth Estimation (APBE). The proposed scheme uses the channel busy state, which is affected by transmitting or receiving processes caused by carrier sensing. Therefore, the sender and the receiver node should be synchronized using various states that can be affected by other nodes. Moreover, the proposed scheme was developed with the involvement of relevant calculation of possible overhead caused by control messaging that occurs in the Media Access Control (MAC) layer and collision probability caused by data flow from hidden nodes. The result showed that the proposed scheme can estimate the available bandwidth of wireless networks more accurately than DLI-ABE and APBE.

“…This poor performance is shown in the results published by Borgo et al [1] and Jayasuriya et al [2]. Additional literature detailing the impact of problem nodes include: [3], [4], [5]. Several analytical models have been developed to examine the performance of the IEEE 802.11 MAC, and to evaluate the impact of varying the PCST.…”

Abstract-This survey provides a comprehensive review of existing physical carrier sensing enhancements for IEEE 802.11 wireless networks. The original physical carrier sensing mechanism, used by wireless stations to gain access to the medium, is limited. Consequently, IEEE 802.11 networks are vulnerable to the presence of hidden and exposed nodes. Such nodes can significantly decrease system performance by increasing the collision rate and decreasing the channel spatial reuse. The value of the physical carrier sensing threshold is a key factor influencing the presence of hidden and exposed nodes in a wireless network. Several enhancements have been proposed in the literature, which attempt to mitigate the loss in performance caused by the limited carrier sensing. Firstly, the notion of an optimum carrier sensing threshold has been studied, and results indicate that it can be tuned to an optimum value. Building on the positive early results, further work was performed to develop mechanisms that dynamically adjust the threshold according to varying network conditions. This article presents an in-depth survey of the existing literature in the area, detailing the various approaches and their efficacy in addressing the problem of hidden and exposed nodes (and consequently increasing performance). It offers a comparison of the techniques, by evaluating the models, limitations, assumptions, and performance gains.
