Multimedia transmission in wireless networks requires high quality of service in terms of packet error rate (PER), throughput and packet delay. InterSector/Intra-Sector Scheduling (ISISS) has been proposed [1] to use basestations coordination in packet scheduling to reduce PER by avoiding (minimizing) concurrent transmission of potential cochannel interferers. Since ARQ schemes can also be used...

Optical burst switching is a promising solution for terabit transmission of IP data bursts over WDM networks. One of the key components in the design of optical burst-switched nodes is the development of channel scheduling algorithms that can efficiently handle data burst contentions. Currently, traditional scheduling techniques use wavelength conversion and buffering to resolve burst contentio...

Hybrid architectures with electronic buffering /processing and optical switching fabric are receiving a lot of attention as potential candidates for the design of scalable high. performance switches/routers. However, the reconfiguration overhead of optical fabrics introduces new challenges for the traffic scheduling across these switches. Existing algorithms proposed for this architecture can b...

The time - cost tradeoff problem is one of the most critical issues in the project scheduling field and so far, a lot of research has been done with a variety of quantitative and qualitative approaches on this subject. In this research, we intend to provide a two - objective mathematical model which balances crash and delay for activities. So that it provides the right tools for decision makers...

A resource scheduling scheme is presented to improve throughput and fairness for NRT packet data traffic on the downlink shared channel of a UMTS WCDMA network supporting multiple services. The proposed Fair Resource Scheduling (FRS) scheme takes into account link conditions to enhance throughput and provides fair resource sharing among traffic flows. FRS includes service priority handling duri...

-Crosspoint buffered crossbar switches have gained much attention due to simple distributed scheduling algorithms. However, almost all the algorithms proposed for buffered crossbar switches either have unsatisfactory scheduling performance under non-uniform traffic or poor service fairness between input traffic flows. In order to overcome the disadvantages, in this paper we propose a novel effi...
