Gray hole attacks (a.k.a selective forwarding attacks) are a special case of denial of service (DoS) attack, where a misbehaving mesh router just forwards a subset of the packets it receives but drops the others. In wireless networks, it is particularly hard to detect the presence of such attackers because a packet loss over the wireless link can be due to bad channel quality, medium access collisions,...
Wireless Mesh Networks (WMNs) are multi hop networks in which the mesh clients rely on static mesh routers (or directly via other mesh clients) to relay data from one point to another in a multihop fashion. WMN gained significant attention because of the numerous applications it supports, e.g., broadband home networking, community and neighborhood networks, delivering video, building automation, in...
Wireless Mesh Networks (WMNs) have emerged recently as a promising technology for next-generation wireless networking to provide wide variety of applications that cannot be supported directly by other wireless networks. In WMNs, security is turning out to be a major concern and little attention has been paid to this topic by the research community. In this paper, we investigate a serious security...
The static nature of mesh nodes imposes requirements for designing routing metrics that support high throughput and low packet delay. This paper considers the problem of interference-load aware routing in multi channel wireless mesh networks. We propose a new Interference-Load Aware routing metric, ILA, that finds paths with reduced inter-flow and intra-flow interference. The aim of this metric is...
