The aggregate capacity of wireless mesh networks is severely affected by interflow interference. Directional antennas and multiple channels are two well known techniques which can be applied to mitigate interflow interference. In this work, a network architecture is proposed to incorporate directional antennas with multiple orthogonal channels effectively to enhance the performance of wireless mesh...
Explicit path setup and constraint-based routing make Multi Protocol Label Switching (MPLS) a suitable technology to consider QoS constraints of the user and traffic engineering (TE) objectives of the provider. This work focuses on the problem of selecting bandwidth guaranteed path for MPLS based networks. The selected path should also fulfill the provider's objective of reducing the blocking probability...
A multi-radio Wireless Mesh Network (WMN) is a multi-hop network that consists of mesh routers and mesh clients, where mesh routers are equipped with multiple radio interfaces and form the backbone of the mesh network. To provide backbone support, it is necessary to reduce interference and balance load in Wireless Mesh Networks (WMNs). We propose load-aware routing metric (LARM), which captures the...
Cognitive radio networks offer the promise of adaptively allocating resources on the fly. In this paper, we describe an interference mitigation technique that relies on intelligent resource allocation across a mesh network. In previous work, we presented a method for improving the performance of wireless mesh networks (WMN) through the use of multichannel wormhole switching. An approximate 800-fold...
