....Section 3 presents a formal problem formulation, while Section 4 describes the algorithms we used to search optimal tree topologies. We discuss the experimental results in Section 5. Finally, we conclude our work in Section 6. 2. BACKGROUND AND RELATED WORK 2. 1 FireWire Bus FireWire (IEEE1394) [4] is a high speed serial bus standard. 1394a currently supports transmission speeds up to 400Mbps, and the new 1394b standard [1] will support transmission speeds of 800Mbps and 1600Mbps. FireWire was designed to connect a computer to peripherals like hard disks, scanners, and consumer electronics ....

....into custom protocols vs. standard protocols. This paper does not attempt to propose a new standard but is intended to demonstrate how an existing standard can incorporate energy efficient optimizations. More specifically, we investigate topology selection for FireWire busses. FireWire (IEEE1394) [1] is a high speed serial bus architecture, supporting two data transfer types: asynchronous and isochronous. It is hot pluggable and a single bus can connect up to 63 devices. The packets transferred can take up to 16 hops for a maximum total distance of 72 meters. When a new node is attached to ....

....nodes on a real time control network. Hence, in NCSs, real time sensing and control data are transmitted on the network, and network nodes need to work closely together to perform control tasks. Current candidate networks for NCS implementations are DeviceNet [5] Ethernet [6] and FireWire [7], to name a few. Each network has its own protocols that are designed for a specific range of applications. Also, the behavior of an NCS largely depends on the performance parameters of the underlying network, which include transmission rate, medium access protocol, packet length, and so on. There ....
....network messages are prioritized, higher priority messages have a better chance of timely transmission. The TP protocol appears in token bus (IEEE Standard 802.4) token ring (IEEE Standard 802.5) 6] and the fiber distributed data interface (FDDI) MAC [13] architectures; TDMA is used in FireWire [7]. A timing diagram for this type of network is shown in Fig. 3. These protocols eliminate the contention for the shared network medium by allowing each node on the network to transmit according to a predetermined schedule. In a token bus, the token is passed around a logical ring, whereas in a ....
