This study investigates a novel streaming architecture consisting of home-to-home online (H2O) devices that collaborate to provide on-demand access to a large selection of audio and video clips. An H2O device consists of a high bandwidth wireless communication component, a powerful processor, and gigabytes of storage. This study investigates three families(More)
This study investigates replication of data in a novel streaming architecture consisting of ad-hoc networks of wireless devices. One application of these devices is home-to-home (H2O) entertainment systems where a device collaborates with others to provide each household with on-demand access to a large selection of audio and video clips. These devices are(More)
This paper focuses on a greedy data placement strategy for a mesh network of peer-to-peer devices that collaborate to stream continuous media, audio and video clips. The greedy placement strategy, termed Simple, strives to maximize the number of references served by the local storage of a peer. We analyze two policies to realize this placement:(More)
While the cost per megabyte of storage is economical, sharing storage might be expensive because delivery of a clip occupying the shared storage requires bandwidth. This is especially true for mesh networks where devices are constrained by the radio-range and bandwidth of their wireless networking card. Assuming a device, termed a peer, is configured with a(More)
