The links in an ad hoc or wireless mesh network are normally kept alive by the exchange of beacon-messages between neighboring nodes. These beacons are prone to collisions with traffic from hidden nodes. If several beacons are lost due to overlapping transmissions, the node expecting the beacons erroneously assumes that the link is down. This is called an apparent link-failure. This paper provides...
Opportunistic routing has emerged as a promising approach to cope with unreliable and unpredictable wireless links in static multi-hop wireless networks. Most existing opportunistic schemes force strict timing between the potential forwarders in order to reduce the number of redundant packet copies generated during the forwarding process. Alternative opportunistic schemes have been also proposed,...
Wireless mesh networks (WMNs) have emerged as a key technology for next generation wireless networks showing rapid progress and inspiring numerous applications. The persistence driving force in the development of WMNs comes from their envisioned advantages including extended coverage, robustness, self-configuration, easy maintenance, and low cost. However, to support real-time applications, WMNs must...
Cooperative communication is a new physical layer technique which improves link capacity by exploiting broadcast nature and spatial diversity of wireless channel. The introduction of cooperative communication in wireless networks changes the traditional definition of link and the contention relationship among links. In this paper, we focus on cooperative communication aware routing protocol design...
This paper studied and analyzed expected throughput metric (ETP), found out that it made a conservative estimate for long path, and it didn't take into account the impact of node's loading on the performance of path. In view to the problem, this paper assumed the interference range of links as two hops, and proposed the definition of node's loading in wireless mesh network, and combined the two with...
