Multi-path routing is effective to enhance network availability, by selecting multiple failure-independent paths for reaching one destination in the hope to survive individual path failures. Researchers suggest to select IP-layer topologically disjoint paths, assuming that they are failure-independent and can hardly fail simultaneously. Unfortunately, failure correlations lurking behind the IP-...

Designing reasonable MAC scheduling strategies is an important means to ensure transmission quality in wireless sensor networks (WSNs). When there exist multiple available routes from the source destination, it necessary combine a data traffic allocation mechanism and design multi-path scheme order QoS. This paper develops resource method for multi-channel networks, which uses random-access tec...

In this paper, we consider the quality of communication paths in wireless multi-hop networks. A wireless multi-hop network consists of wireless nodes and wireless links. In this network, there usually exist various candidate paths to connect a source and a destination. We can evaluate the quality of each of the candidate paths by using a metric for link quality, and as a result, we can choose t...
