This report examines potential fairness problems associated with a model based approach to TCP-friendly ow control for non-TCP traac. In speciic, such an approach involves using a TCP-friendly formula that estimates the throughput of a TCP session with the same end-to-end traac characteristics as the non-TCP connection under consideration. The inputs to this formula include the round trip time,...

Transmission loss and noise reduction of reactive mufflers are determined by linear acoustic theory and unsteady flow field study, respectively. The effects of extending the inlet tube of the muffler, adding holes to the extension, and the number of holes on both transmission loss and noise reduction are investigated. In noise reduction analysis, the Navier-Stokes equations and k-ε model are us...

To guarantee quality of service (QoS), the requirements for video transmission such as delay and cell loss rate (CLR) are very stringent. These constraints are difficult to meet if high network utilization is desired. Dynamic bandwidth allocation is thus needed. Video traffic prediction can play an important role in dynamic bandwidth allocation and traffic management in highspeed networks. In t...

Biomedical sensors (BMSs) monitor the heterogeneous vital signs of patients. They have diverse Quality of Service (QoS) requirements including reduced collision, delay, loss, and energy consumption in the transmission of data, which are non-constrained, delay-constrained, reliability-constrained, and critical. In this context, this paper proposes a traffic priority-aware adaptive slot allocatio...

To solve the problem that traffic network of rapid change is easy to fall into the situation of network congestion, based on the network load information, we use the average transmission time and local interface queue length information to find the path of the load balancing, and select minimum load channel through load-aware channel allocation. Considering interference suppression, load balanc...

In existing DMT (discrete multi-tone) systems with adaptive bit allocation a deterioration of the transmission channel may lead to increased bit error rates, and even to the loss of connection. In most cases this disturbed channel would allow a stable transmission using a new bit allocation (possibly with reduced data rate), after a further initialization phase. We propose dynamic adaptive DMT ...

With Asymmetric Multiple Description Coding we address the transmission case where there is a plethora of communication paths between sender and receiver, all with a different bandwidth and different levels of reliability (in terms of packet loss rate). For this scenario we have several possibilities for coding and transmission at our disposal, namely Round-Robin transmission, Layered Coding, T...

IEEE 802.11e WLAN has provided a new access mechanism called the hybrid coordination function (HCF) for quality-of service (QoS) support[1]. Here, we provide HCF scheduler to allocate transmission opportunities (TXOPs) for the stations. TXOP is the time under which a station can send its burst of data packets to other stations. An station can be either in the good or bad channel state and it ca...
