Executive Summary

Wireless Mesh Networks (WMNs) promise to extend high-speed wireless connectivity beyond what is possible with the current WiFi-based infrastructure. However, their unique architectural features leave them particularly vulnerable to security threats. In this paper, the authors describe various forms of sophisticated attacks launched from adversaries with internal access to the WMN. They further identify possible detection and mitigation mechanisms. Wireless Mesh Networks (WMNs) continue to receive significant interest as a possible means of providing seamless data connectivity, especially in urban environments. Architecturally, such networks evolved from classic mobile ad hoc networks, targeting long-range transmissions with emphasis on network throughput and connectivity. WMN applications include stationary deployments (e.g., community networks, hierarchal sensor networks) as well as mobile ones (e.g., intelligent transportation systems, tactical military networks).
