As commodity workstations become faster with increases in processor technology, the need for higher performance network interfaces becomes more pressing. While current commodity network interface cards provide ample bandwidth for bulk data transfers, the latency imposed on small messages can be large. However, to attempt to harness the potential compute power of a cluster of workstations at com...

this study seeks to examine how a company can select the best intermediary for its marketing channels with minimum of criteria and time. a theoretical framework is proposed based on the most important tasks of intermediary and the criteria to measure them. there are four basic tasks and thirty criteria in three independent levels. subsequently, an exploratory case study in iranian food industry...

To localize mobile devices in the indoor environment, it is considered as a natural approach to make use of a commodity device. One popular work utilizes the physical layer information of WLAN devices. The information includes a beneficial characteristic, that is, the possibility of eliminating some degree of multipath fading effects. This paper deals with some experiments to improve the indoor...

â â â  â â â  abstract â  using a structural var with block exogeneity, diagonality and identifying restrictions, this paper analyzes: first, the macroeconomic linkages among the oil price, u.s. output, interest rate, money supply, general price level and exchange rate and second, the relationships of the macroeconomic variables with the price indices of ten international nonfuel commodity grou...

Despite availability of multiple non-overlapping channels in the 2.4GHz and the 5GHz spectrum, most IEEE 802.11-based multi-hop ad hoc networks operate in a single channel. This substantially reduces the bandwidth available to each node due to interference between successive hops on the same path as well as between neighboring paths. Figure 1 depicts the severity of such interference. As a resu...

In this demonstration, we present a prototype of a crosstechnology communication (CTC) system that allows a Bluetooth Low Energy (BLE) device to directly send data to a Wi-Fi device using commodity hardware. Towards this goal, we use energy burst patterns to encode information on overlapping channel frequencies. With this demonstration, we prove the feasibility of our holistic CTC approach for ...

In recent years, propagation channel characteristics have been effectively used in several applications such as motion sensing and position detection. Considerable attention has paid to channel-sounding methods that are easy utilize using low-cost devices. This paper presents a device-free indoor location estimation method the spatio-temporal features of radio channels 2.4 GHz-band three-by-thr...
