Design and capacity performance analysis of wireless mesh network [PDF]

open access: yesProceedings of the International Conference on Mobile Technology, Applications, and Systems - Mobility '08, 2008
From the network operator’s point of view, the high CAPEX/OPEX cost resulting from fixed/wired backhaul links can be inhibitive to successful deployment of broadband wireless services. The emerging wireless mesh network (WMN) technology is seen as one of the potential solutions which may reduce wired backhaul dependency through multihop transmission ...

Performance Analysis of Routing Protocols for WLAN Mesh Networks [PDF]

open access: yesThe KIPS Transactions:PartC, 2007
Mesh networks using WLAN technology have been paid attention as a key wireless access technology. However, many technical issues still exist for its successful deployment. One of those issues is the routing problem that addresses the path setup through a WLAN mesh network for the data exchanges between a station and a wired network.

Dynamic Modeling and Nonlinear Analysis of a Spur Gear System Considering a Nonuniformly Distributed Meshing Force

open access: yesApplied Sciences, 2022
In previous studies, the meshing force of a gear system is usually treated as being uniformly distributed for the convenience of analysis. In practical applications, however, it is nonuniformly distributed along the line of action due to machining errors,
