Cross-layer security and resilience in wireless mesh networks

Security and Resilience has become an important concern in the security design and architecture of future wireless networking technologies like Wireless Mesh Networks (WMN) [1, 2]. Network operators and service providers consider mesh networking to be a serious candidate to solve the so called “last mile problem” based on their wider coverage than traditional wireless LANs and their lower deployment cost than 3G cellular networks. While there are several usage scenarios [3] and business opportunities [4] and there exist the so called community based mesh networks that are operated by individuals, the real business potential lies in operator based mesh networks. Such examples include Ozone's mesh network in Paris (www.ozone.net/en/) and The Cloud in the City of London (www.thecloud.net). If such pilot projects turn out to be successful, then mesh networking may become extremely popular and wide-spread.
