Abstract
Wireless mesh networks (WMNs) are a promising technology that has emerged with the combination of several wireless networks. These wireless networks and devices communicate in a mesh network manner, to provide edge-to-edge, easy, and cost-effective data communication. Many current and future promising applications depend on WMN and one of the most important applications is eHealthcare, where the confidential information transfers with the help of WMN. WMN devices communicate over a wireless medium, which opens the system to a number of vulnerabilities; thus, an intruder can launch malicious activities through many types of attacks that can result in denial of service (DoS). In this paper, the available solutions to overcome these attacks are simulated and evaluated in terms of data packet delivery ratio, end-to-end delay, and network throughput and under different cases of static and mobile WMNs, which helps in providing suggestions to enhance existing protocols and mitigate the effect of DoS caused by such attacks.
Highlights
Security is always a major concern in transferring information from the source to the destination, whether it is the manual postal service or data communication in today’s digitized world, especially, applications like eHealthcare that are built to provide assistance for a very sensitive purpose
Ad hoc On-Demand Distance Vector Routing (AODV) implementation is available for simulation tools, including OMNET++, which was selected to be used in simulation of these attacks because of its suitability [25]
This was not an effect of the attack since the increase in the number of malicious nodes was not reflected in end-to-end delay; rather, it was associated with how PASER selects the optimal path and the time taken to validate the position of the nodes and to validate routing packets
Summary
Security is always a major concern in transferring information from the source to the destination, whether it is the manual postal service or data communication in today’s digitized world, especially, applications like eHealthcare that are built to provide assistance for a very sensitive purpose. A WMN consists of nodes that communicate using wireless technology to provide connectivity These nodes are usually mesh clients such as cell phones and mesh routers, including Wi-Fi access points. WMN nodes can be connected and organized in three main ways to form three types of WMNs: infrastructure/backbone, client, and hybrid WMNs. The main characteristics and benefits of WMNs are coverage, mobility, scalability, heterogeneity, and compatibility [3] and provide network services such as Internet access, video conferencing, and voice communication, and they help in transferring data between networks. The main characteristics and benefits of WMNs are coverage, mobility, scalability, heterogeneity, and compatibility [3] and provide network services such as Internet access, video conferencing, and voice communication, and they help in transferring data between networks This makes a WMN suitable for many applications in both military and civilian fields. In such applications, wired communication may not be possible or risky, so a WMN is a more suitable solution because it offers easy and rapid connectivity through a wireless medium
