In this paper, we consider wireless transmissions over directional multiple-input single-output (MISO) two wave with diffuse power (TWDP) fading channels, subject to interference the same type of channel. TWDP is known exhibit an outage behavior that can be even worse than Rayleigh and has experimentally been observed in a number vehicular channel measurement campaigns. To enhance reliability m...

Multimedia transmissions over IP networks have increased significantly in recent years. Both user expectations and traffic levels have increased as well. One way to take these into account is for senders to receive and respond to feedback about the quality of their transmissions. We have built a feedback controlled multimedia transmission system, and we have tested and analysed the influence of...

IEEE 802.16e devices may enter sleep mode to conserve energy. There has been some work studying how to schedule device’s packet transmissions to maximize the device’s sleep period while meeting associated QoS (quality of service) requirements. This paper proposes two schemes that attempt to save more energy for a given sleep schedule by accelerating or deferring scheduled packet transmissions w...

Abstract: This paper presents a design approach for the configuration synthesis of series-parallel hybrid transmissions with eight-bar mechanisms. The final design consists of 54 mechanisms with eight members and twelve joints including a simple planetary gear train (PGT) and a double planet PGT. Then, by using the techniques of power and clutch arrangements, new series-parallel hybrid transmis...

The expected number of transmissions is a very important parameter to evaluate the multicast performance. It is often used to estimate the bandwidth consumption of tree-based reliable multicast where some special receivers or routers are assigned for retransmission handling of each domain. In this work, we will analyze and simulate the tree-based multicast transmissions to obtain the number of ...
