In this paper, a parameter uniform numerical method based on Shishkin mesh is suggested to solve a system of second order singularly perturbed differential equations with a turning point exhibiting boundary layers. It is assumed that both equations have a turning point at the same point. An appropriate piecewise uniform mesh is considered and a classical finite difference scheme is applied on t...

Wall mesh is a degree mesh obtained from the ordinary degree mesh by deleting one degree from each node Its node degree is reduced by while its diameter is almost the same as the degree mesh It is computationally equivalent to the degree mesh since a degree mesh can be embedded in a wall mesh with dilation and congestion As a result all existing algorithms for degree meshes can be e ortlessly p...

This paper describes the implementation of wireless mesh nodes based on the IEEE 802.11s draft where the motivation is to build a real life mesh network. The mesh nodes developed have mesh, mesh access point and mesh portal functionalities simultaneously. The mesh nodes use different radios for mesh and access point functionalities, thus giving better service to client stations. Both reactive a...
