Analysis of Denial of Service Impact on Data Routing in Mobile eHealth Wireless Mesh Network

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.
