No longer is shared storage a niche enjoyed by only large, wealthy corporations. Internet SCSI is leveling the playing field by making shared storage available at a reasonable cost to anyone. By leveraging the ubiquitous Ethernet networks prevalent in most organizations, IT staff training costs for iSCSI are very low and result in quick, seamless deployments. In this How do I… Scott Lowe shows you how to install and configure Microsoft’s iSCSI initiator.This download is also available as an entry in the TechRepublic How do I… blog.

Ad hoc wireless networks are power constrained since nodes operate with limited battery energy. To maximize the lifetime of these networks (defined by the condition that a fixed percentage of the nodes in the network “Die out” due to lack of energy), network-related transactions through each mobile node must be controlled such that the power dissipation rates of all nodes are nearly the same. Assuming that all nodes start with a finite amount of battery capacity and that the energy dissipation per bit of data and control packet transmission or reception is known, this paper presents a new source-initiated (on demand) routing protocol for mobile ad hoc networks that increases the network lifetime.

Sensor nodes have limited sensing range and are not very reliable. To obtain accurate sensing data, many sensor nodes should be deployed and then the collaboration among them becomes an important issue. A tree-based approach has been proposed to facilitate sensor nodes collaborating in detecting and tracking a mobile target. As the target moves, many nodes in the tree may become faraway from the root of the tree, and hence a large amount of energy may be wasted for them to send their sensing data to the root.

The current wireless technologies such as IEEE 802.11 (Wi-Fi) make ad hoc networking viable for small regions involving a few tens of mobile nodes, but such networks are unreliable. This paper investigates the benefits of adding a few infrastructure nodes to an otherwise ad hoc network. These infrastructure nodes are interconnected among themselves with point-to-point (p2p) links in addition to Wi-Fi capability.

To enable wireless Internet and other data services using mobile appliances, there is a critical need to support content-rich cellular data communication, including voice, text, image and video. However, mobile communication of multimedia content has several bottlenecks, including limited bandwidth of cellular networks, channel noise, and battery constraints of the appliances. This paper addresses the energy and bandwidth bottlenecks of image data communication. The paper presents an energy efficient, adaptive data codec for still images that can significantly minimize the energy required for wireless image communication, while meeting bandwidth constraints of the wireless network, the image quality, and latency constraints of the wireless service.
