AbsfmdI n this paper we discuss the delivery of cacheable streaming content in a network with mobile nodes. Caching and regional replication are important techniques for traffic localizatioo and reduction in load on the network and the content sewer. However traditional caching schemes alone cannot suffice for localization of streaming multimedia traffic in oetworlw with mobile nodes. This is m...

Today power consumption is considered to be one of the important issues. Therefore, its reduction plays a considerable role in developing systems. Previous studies have shown that approximately 50% of total power consumption is used in cache memories. There is a direct relationship between power consumption and replacement quantity made in cache. The less the number of replacements is, the less...

The Simultaneous Optical Multiprocessor Exchange Bus (SOME-Bus) is a low-latency, high-bandwidth interconnection network which directly links arbitrary pairs of processor nodes without contention, and can efficiently interconnect over one hundred nodes. Each node has a dedicated output channel and an array of receivers, with one receiver dedicated to every other node’s output channel. The SOME-...

In this paper, downlink delivery of popular content is optimized with the assistance of wireless cache nodes. Specifically, the requests of one file is modeled as a Poisson point process with finite lifetime, and two downlink transmission modes are considered: (1) the base station multicasts file segments to the requesting users and selected cache nodes; (2) the base station proactively multica...

BitTorrent (BT) is an effective tool for large-scale P2P content services in the face of dynamic nature of Internet. A P2P content service is usually characterized by the fact that its users leave and join the service frequently and are self-interested. It is further complicated by the flash crowd phenomenon. However, BT does not perform well in streaming applications in which contents are supp...

Cooperative caching is an efficient way to improve the performance of data access in mobile wireless networks, by cache nodes selecting different data items in their limited storage in order to reduce total access delay. With more demands on sharing a video or other data, especially for mobile applications in an Internet-based Mobile Ad Hoc Network, considering the relations among data items in...

Video-on-demand (VOD) is expected to become one of the most important and successful services to be offered on emerging technologies. There is not just an interest in the delivery of digital video for home entertainment purposes, but there are also several educational and commercial benefits from this service. However, for this service to become viable, it is important that the video servers me...

Conventional snoopy-based chip multiprocessors take an aggressive approach broadcasting snoop requests to all nodes. In addition each node checks all received requests. This approach reduces the latency of cache to cache transfer misses at the expense of increasing power. In this paper we show that a large portion of interconnect/cache transactions are redundant as many snoop requests miss in t...

As technological advances continue to be made, the demand for more efficient distributed multimedia systems is also affirmed. Current support for end-to-end QoS is still limited; consequently mechanisms are required to provide flexibility in resource loading. One such mechanism, caching, may be introduced both in the endsystem and network to facilitate intelligent load balancing and resource ma...

Congestion control is one of the key research topics in relation to routing algorithms wireless sensor networks (WSNs). In this paper, we propose a congestion-aware algorithm (CARA) for unlimited-lifetime by integrating geographic distance and traffic load nodes. The takes alleviating congestion as primary purpose considers node itself local network traffic. According between nodes, CARA define...
