Cloud Radio Access Network (C-RAN) enhances the utilization of computing and radio resources by concentrating Baseband Unit (BBU) at a data center. It is essential to find a flexible way to manage the computing resource since processing power has become the majority of system power in C-RAN. The computing resource demand of users can be scaled according to the modulation bits and other parameters...
System identification (SI) using small samples is a problem of interest in several applications. However, parameter estimation in these situations is a challenge since classical identification techniques (based on prediction-error methods) are guaranteed to be efficient and consistent only under asymptotic (large sample) conditions. In addition these techniques need the knowledge of delay and order...
Reduction of end-to-end network delays is an optimization task with applications in multiple domains. Low delays enable improved information flow in social networks, quick spread of ideas in collaboration networks, low travel times for vehicles on road networks and increased rate of packets in communication networks. Delay reduction can be achieved by both improving the propagation capabilities of...
Presently, almost all timing analyses and optimization tools are based on the strategy of setup and hold time constrained flip-flop timing model. However, this is a big mismatch with the timing characteristic of the real life flip-flops, which is so called flexible flip-flop timing, in which the clock-to-Q delay of every flip-flop may vary dynamically according to its setup and hold skews. This work...
Delay is a significant parameter that is used in the optimization of signal settings for intersections and the estimation of the level of service at signalized intersections, and it is also a parameter that is difficult to estimate. Based on the existing theory of delay at signalized intersection, this paper analyzes the delay at a signalized intersection of each phase for entrance with the arrival...
Sink mobility has become an increasingly important requirement of various sensor network applications. Handling such mobile sink conditions brings new challenges to large-scale sensor networking. This investigation proposed a hybrid-structure routing protocol (HSRP) that combines the benefits of grid-based and cluster-based structures. Grid-based structure is designed to solve the cluster head selection...
