Being different from other networks, the load and direction of data traffic for wireless sensor networks are rather predictable. The relationships between nodes are cooperative rather than competitive. These features allow the design approach of a protocol stack to be able to use the cross-layer interactive way instead of a hierarchical structure. The proposed cross-layer protocol CLWSN optimiz...

Time slotted channel hopping is an enhanced access mechanism for IEEE 802.15.4 that improves many aspects of the original protocol, like determinism and power consumption. Besides preventing collisions, time slotting allows motes to stay asleep most time. In addition, achieves more stable communication, in terms packet losses transmission latency, spite wireless spectrum variations. this paper,...

The recent explosive growth in the Internet technology has made it imperative to have a network which supports a very high bandwidth.Wavelength division multiplexing (WDM) based on optical networks are becoming a viable solution to meet this ever-increasing bandwidth demand. Optical burst switched (OBS) networks provide a good solution for a very high traffic influx which is generally bursty in...

This thesis focuses on the planning, scheduling, and pricing of ad slots in technology-enabled modes of advertising, including webpage banner ads, video games, electronic outdoor billboards, and the next generation of digital TV. This work contributes to practice by being the first academic work to rigorously study the scheduling of dynamic in-game advertising; contributes to the body of theory...

The paper presents an accurate analytical subdomain model for predicting the electromagnetic performance in symmetrical dual three-phase surface-mounted permanent magnet synchronous machine (PMSM) under open-phase faulty conditions. derivations are extended from previous models accounting slotting effects. Compared with most conventional traditional machines nonoverlapping winding arrangement, ...
