    Digital image stabilizer and video encoder are two important components of a digital video camera. The digital image stabilizer compensates the image movement caused by hand jiggles and thereby improves the perceptual quality of the captured image sequence, while the video encoder compresses the huge amount of video data down to a reasonable size. Both components require the motion information of ... View full abstract»

    Loss differentiation is recommended as a service differentiation provided by an assured forwarding (AF) per-fop behavior (PHB) in differentiated service (DiffServ) architecture. An active queue management (AQM) technique is addressed as a suitable alternative to realize the service differentiation because the AF PHB should attempt to minimize long-term congestion while permitting short-term conges...

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (588 KB) | HTML iconHTML

    We consider the problem of traffic routing in a two-node parallel-link communication network shared by several competing teams of users. Each team has various types of entities (jobs or packets) to be routed from one node to the other on the network. The users in each team cooperate for the benefit of their own team so as to achieve optimal routing over the network links. The teams, on the other h... View full abstract»

    Certain types of non-Gaussian noise sources in multicarrier communication systems behave effectively as modulating signals that control the first moment of the background Gaussian noise. The composite noise, which is the aggregate of the Gaussian and non-Gaussian noise, has a probability density function that is conditionally Gaussian with non-zero average, hence referred to as biased-Gaussian. Im... View full abstract»

    In the mobile IP-enabled wireless LAN (WLAN), packet transfer is interrupted due to the handoff of mobile node (MN), which results in burst packet losses. This transient behavior hurts time-critical streaming media applications. In case of one-way streaming media applications, it is well known that pre-buffering at the receiver side is effective in overcoming network fluctuations. However, determi... View full abstract»

    The well-known edge server bottleneck is shown in this paper to be the result of a mismatch between the general-purpose architecture and the special-purpose data functions it was not intended to perform exclusively. Six overheads are identified that contribute significantly to the bottleneck. To solve this bottleneck problem, a solution is to apply the principle of separation between control and d...

    In this paper a new way of saving power is expounded. With the different modulation, different energy levels are needed, and then the constant length of packet can be changed to the different length of symbol. Therefore it changes the average length of symbols of all users. At the same time, the variable length of symbols can influence the throughput and delay of the system. But using the CSMA/CD,...

    The seamless handover of streamed video in a WLAN with UDP as the transport layer is considered. The use of handover for stationary nodes in the case of network congestion is motivated. Next, the relationship between delay and loss in WLANs is studied, with the conclusion that delay can be used as an indicator of when loss is likely to occur. Delay can therefore be used as a basis of a handover sc... View full abstract»

    Delay estimation is a difficult problem in computer networks. RTT (round trip time) is often used as an approximation of the delay, but because it is a sum of the forward and reverse delays, the actual one-way delay cannot he estimated accurately from RTT. Accurate one-way delay estimation becomes crucial because it serves a very important role in network and application design. This paper propose... View full abstract»

    UPnP is middleware designed for network "plug and play". It uses technologies developed specifically for UPnP but also borrows technologies such as SOAP from Web services for remote procedure calls. SOAP has been criticised as inappropriate for Web systems and this paper shows that these criticisms are equally applicable for UPnP. It shows how mechanisms built on REST principles can produce smalle... View full abstract»

    The number of broadband cable access subscribers in the United States is rapidly approaching 30 million. However there is very little research that has evaluated TCP/IP in modern cable environments. We have developed a model of the data over cable system interface specification (DOCSIS) 1.1/2.0 MAC and physical layers using the 'ns' simulation package. In this paper we show that the interaction of... View full abstract»
