  • Heterogeneous search in unstructured peer-to-peer networks

    Resource search or discovery is a fundamental issue in peer-to-peer (P2P) and grid studies. Search objects, or resources, can be cycles, storage spaces, files, services, addresses, and so on. In most search methods cited in related literature, peers run uniform forwarding logic; we call these homogeneous search (HMS) techniques. Although various efficient and scalable HMS techniques exist, previous studies show that the performance of any single method isn't perfect on all sides. Therefore, our research mixes those HMS techniques to increase performance; we call this heterogeneous search (HES). We explore the feasibility of HES evaluated in the context of timekeeping P2P networks from our prior studies. Our simulation results show HES to have significant advantages over other methods.

  • RFID: not quite prime time, but dawdle at your own risk

    The new year signaled a turning point in the deployment of supply chain management's "next big thing" - radio frequency identification, or RFID. RFID isn't really new. For several years, military and security applications have deployed fairly sophisticated implementations of active RFID, which uses battery-powered radio-equipped tags to transmit pertinent information. However, the next wave of RFID, known as passive RFID, features cheaper nonenergized tags and is just poking into the marketplace. View full abstract»

  • I want my IPTV: Internet Protocol television predicted a winner

    Among the technology winners IEEE Spectrum magazine recently predicted to surge in 2005 is Internet Protocol television. IPTV delivers a relatively low-speed broadband TV connection (2.2 megabits per second) through telephone wires. By using a legacy copper network instead of a more costly optical-fiber upgrade, IPTV delivers a multiplicity of programming choices that's expected to enable telephone carriers to one day give cable providers a run for their money.
