With the increasing popularity of 802.11 wireless technology, such equipment has recently been used to set up long distance links for wireless mesh networks. To be able to increase the range of 802.11 equipment directional antennas are required. In this paper, we investigate the effects of interference between collocated directional antennas, which would be the case for a typical multi-hop node...

Over the past several years the topics of energy consumption and energy harvesting have gained significant importance as a means for improved operation of wireless sensor and mesh networks. Energy-awareness of operation is especially relevant for application scenarios from the domain of environmental monitoring in hard to access areas. In this work we reflect upon our experiences with a real-wo...

Considerable research has focused on the design of routing protocols for wireless mesh networks. Yet, little is understood about the stability of routes in such networks. This understanding is important in the design of wireless routing protocols, and in network planning and management. In this paper, we present results from our measurement-based characterization of routing stability in two net...

In a multihop wireless mesh network, interference among links has a significant impact on the link capacity. Thus, characterizing the interference is critical in understanding and improving the performance of the network. A common scenario in a mesh network is the existence of multiple interferers. Modeling the effect of multiple interferers is challenging as the interference level not only dep...

Wormhole attacks, as a devastating type of threats in wireless mesh networks, have received much attention in recent years. This paper proposes a type of wormhole attack model and its corresponding detection scheme. In this scheme, the combination of a number of techniques, such as distributed voting, watch-nodes-based detection and identity-based cryptosystem are used. The simulation results a...

In this paper we apply the concept of overlay cognitive radio to the communication between nodes in a wireless mesh network. Based on the overlay cognitive radio model, it is possible to have two concurrent transmissions in a given interference region, where usually only one communication takes place at a given time. We analyze the cases of wireless mesh networks with regular and random topolog...

Trust models that rely on recommendation trusts are vulnerable to badmouthing and ballot-stuffing attacks. To cope with these attacks, existing trust models employ different trust aggregation techniques to process the recommendation trusts and combine them with the direct trust values to form a combined trust value. However, these trust models are biased as recommendation trusts that deviate to...

Wireless Mesh Networks can give an answer for many open issues in the field of wireless networks. For WMN to be effective enough, it is required for a chosen routing protocol based on routing metrics that fits application needs to be used properly. Until now, many different routing protocols have been proposed. All of them have their own characteristics and there is no easy way to make any reli...
