“…Imagine an uncovered area in the form of an equivalent ring with internal and external radii Rh and 2R, respectively. Assuming that R = 1, the inner radius of the equivalent ring will be equal In Table 1 calculations are given by formulae (6), (7), as well as absolute ΔR and relative ε deviation Rh from 2R. Table 1 shows that the probability of locating 2-hop nodes at the circle boundary of radius 2R rapidly decreases: So for 17 nodes (8 MPR nodes), 7 cases are possible from 100, for 33 nodes (16 MPR) -2 cases from 100, for 65 (32 MPR) -5 cases from 1000.…”

“…Among the most commonly used routing protocols in wireless networks MANET has a protocol called OLSR (Link State Routing Protocol) [2], which devotes a lot of work. So in [3] the principle and operation of multipoint repeaters (MPR) is discussed and a heuristic approach is proposed for selecting MPR in a mobile wireless environment; [4][5][6][7] are aimed at optimizing the work of the OLSR protocol, which is a complex task, because the protocol contains more than a dozen customizable parameters. In [8][9][10], the problem of finding the upper limit of the number of MPR nodes is considered.…”

Background. At present, the demand in MANET networks is determined by the inherent advantages of these networks over fixed networks, especially in emergency situations. The topology in such networks is extremely dynamic, which required the development of special routing protocols. Although the basics of the theory of the OLSR protocol, which is widely used in these networks, are well known, however, the development of mobile networks requires constant refinements of theoretical positions in accordance with new data on how to calculate the number of multipoint repeaters. Objective. The aim of the paper is to find analytical expressions for calculating the upper limit of the number of multipoint repeaters, the probability of the location of two-hop nodes at the maximum distance from the reference, and checking the correspondence of the results obtained using simulation. Methods. Analytical methods of calculation are used, as well as simulation modeling in the NS-2 software package. Results. Analytical expressions are obtained for calculating the upper limit of the number of multipoint repeaters and the probability of the location of two-hop nodes at the maximum distance from the reference node. A simulation was performed to confirm the theoretical results. Conclusions. The upper bound of the number of one-hop relay nodes is estimated. It is shown that with a low density of nodes in the area under consideration, the value of the upper limit is two times less than that previously determined in the scientific literature. Modeling in the NS-2 software package showed the correspondence of analytical expressions for the calculation of the upper boundary of multipoint repeaters. There are cases when analytical expressions give false results. For these cases, it was proved that regardless of the network density, each two-hop node that is at the maximum distance from the reference node must have its own multipoint repeater. The probability of the location of two-knot nodes at the maximum distance from the reference node is determined.

“…Proactive techniques include the use of rate control, location hiding, and heuristic techniques. Location hiding is regarded as one of the ways that could be used to develop a complete solution to DDoS [13]. It hides the application's IP address so that malicious users cannot target it in case of a DDoS attack.…”

a b s t r a c tWireless Mesh Networks (WMNs) have potentially unlimited applications in the future. Therefore, establishing a viable and secure wireless network routing protocol for these networks is essential. Currently, these networks are being used in connecting large sections of cities by setting up wireless routers at strategic points all around the city. These networks can also support connecting remote areas of the country, instead of having to lay a cable all the way. The nature of applications mentioned above make these networks prone to different attacks. Thus, security of these networks is a serious concern. In this paper, we study the impact of Distributed Denial of Service (DDoS) attacks on WMNs. We base our work on the existing Optimized Link State Routing protocol (OLSR) and we weave in concepts of Learning Automata (LA) to protect the network from this kind of attack. The simulation results for the proposed scheme show that the proposed protocol is effective in the prevention of DDoS attacks in WMNs.

Boukerche et al [44] have used Optimized Link State Routing (OLSR) in order to form a large-scale self-organized WMN. The eminent advantage of a self-organized network is its ability to perform network control and management, which reduces both the developmental complexity and the need for maintenance of these networks.…”

Abstract-Wireless Mesh Network (WMN) is one of the significant forms of the wireless mesh network that assists in creating highly interconnected communication node. Since a decade, there have been various studies towards enhancing the performance of WMN which is successful to a large extent. However, with the upcoming technology of pervasive and dynamic networks WMN suffers from various routing issues, Quality-of-Service (QoS) issue, channel allocation, sustainability of routes which makes the theory contradicting when considering for real-world challenges in wireless networks. This paper, therefore, briefs about fundamental information of WMN followed by a discussion of existing research trends and existing research techniques. Finally, the paper also discusses the open research issues after reviewing the existing research techniques.
