A comprehensive experimental study was carried out on the regular wave attenuation with a trapezoidal pontoontype floating breakwater (FB) in deep water. The functionalities of two simple FB geometries consist of a rectangle and a trapezoid with the slope of 60° were investigated under the wave attack. A two-dimensional wave flume was used in the experiment; the incident, transmitted waves, mooring...
Nowadays, Multi-hop wireless networks have achieved lots of attention due to their ease of development, low cost, and other advantages. Wireless channels have broadcast nature, and a sent packet can be heard by the nodes in the sender's transmission range. This feature is used in opportunistic routing to forward the packets and to enhance the network efficiency. In most of the opportunistic routing...
A new end-point admission control algorithm is proposed. The proposed algorithm helps to manage the network traffic within a domain more efficiently in the next generation network where multiple classes of service are required by different applications. In the existing solutions, when a request for a new traffic is received by the network, according to the admission control mechanism the availability...
DiffServ is assumed as a scalable solution for service differentiation in the Internet. It applies differentiated behaviors on data packets for different quality levels on a per hop basis (PHB). However, it does not have any control on the traffic entering the network and the paths which are traversed by data packets. Therefore, if no complementary mechanism is used with DiffServ, the end-to-end service...

In this paper, we propose a new end-point admission control algorithm which helps to manage the traffic efficiently while providing end-to-end service quality. In this algorithm, users are allowed to temporarily use lower service levels in the routers that the requested service level is not currently available. This local degradation preserves the end-to-end service quality in the acceptable level...
