A lot of work has recently been published regarding metrics that could identify high quality paths in Wireless Mesh Networks (WMN). While results are encouraging, no optimal strategy has yet been identified that could estimate link quality and incorporate both the link reliability measurements as well as the bandwidth capacity. Furthermore, link estimation remains an open problem. Considering multi-user...
To tackle an inherent security weakness of wireless environments, we propose the implementation of a reputation procedure onto the routing protocol Ad-hoc On Demand Vector routing (AODV). This procedure relies on the overal cooperation of nodes taking part to the Wireless Mesh Network. Each node associates a reputation value to its neighbours, which reflects the trust it puts in them. Based on that...
This paper presents a new metric for routing in wireless mesh networks (WMNs). The proposed metric does not only consider the quality of wireless links to choose a high throughput path between a pair of nodes, but it also includes the resulting interference introduced by using such links. The philosophy behind this metric is to choose a good path for an arriving connection, not necessarily the best...
This paper proposes an automatic adaptive k-distance dominating set-based clustering scheme for service discovery in Wireless Mesh Networks. Supernodes and clients form a so-called virtual backbone where clients are at most k hops away from a supernode. The scheme automatically adapts the hop distance between supernodes and clients based on stability metrics to reduce re-clustering situations. We...
Transporting camera surveillance data using wireless networks has benefits of reduced cost and increased flexibility. In this paper, we report a measurement study of wireless camera networks using IEEE 802.11 standards, which are pervasively adopted and supported by a large number of vendors. We studied two testbeds deployed in real-world environments, one in a residential house and the other in an...
