Resumo Due to the raising dependence of people on wireless networks for using critical applications, high level of reliability, security and availability is claimed to assure secure and reliable service operation. Wireless ad hoc networks (WANETs) experience serious security issues even when solutions employ preventive or reactive security mechanisms. In(More)
—Wireless mesh networks (WMNs) have emerged as support for applications on various domains, such as military, financial and healthcare. Those applications claim for high level of both end-to-end performance and security. However, WMNs are naturally susceptible to security issues that can compromise network performance. This paper presents a cross-layer and(More)
—Wireless mesh networks have gained increasing interests, but the lack of security guarantee has retarded their deployment. Security solutions have applied preventive or reactive mechanisms, being inefficient to put all attacks off. We design a survivable architecture for ad hoc and mesh networks to enhance the network capability of providing essential(More)
