Channel allocation or assignment problems have been studied intensively in the literature for the last 25 years. Current directions of this work appear to be in the area of self-organizing or distributed allocation methods, and the type of cellular arrays involved are moving toward complex mixed or hierarchical structures rather than simple arrays of macrocells or microcells. Channel segregatio...

Currently ETSI/BRAN develops standards for HIPERLAN/2, a wireless LAN operating in the 5GHz band and supporting broadband multimedia communication. The standard supports adaptive frequency allocation (AFA) by protocols for field strength measurements and reports. This paper shows simulation results for a decentralized AFA autonomously operating in each access point and using field strength meas...

The evolution of wireless and optical networks will involve not only the adoption of new technologies but also massive changes in how network resources are owned and managed. In this paper, we describe current trends in decoupling resource ownership from service provisioning, which can be observed in both wireless and optical networks. Moreover, we present our vision of how these trends will ev...

On a Wide Area Network (WAN), fragment allocation is a major issue in distributed database design since it concerns the overall performance of distributed database systems. Here we propose a simple and comprehensive model that reflects transaction behavior in distributed databases. Based on the model and transaction information, two heuristic algorithms are developed to find a near-optimal allo...

A national plan is proposed for the equitable allocation of extrarenal organs, with particular reference to the liver. The principles of the plan include preferential use of the organs in the local and regional area of procurement, with national listing of the organs left over after the original cut. At each of the local, regional, and national levels, the allocation is based on total points aw...

In this paper, the authors propose an algorithm-level time redundancy-based concurrent error detection (CED) scheme against permanent and transient faults by exploiting the hardware allocation diversity at the register transfer level. Although the normal computation and the recomputation are carried out on the same data path, the operation-to-operator allocation for the normal computation is di...

Emerging multimedia applications require more bandwidth and strict QoS requirements. To meet these in wireless personal area networks, WiMedia multiband-orthogonal frequency division multiplexing (MB-OFDM) has been designed while consuming low-transmission power. In this article, we increase the wireless bandwidth of the standard MB-OFDM scheme three times using device synchronization, and cons...

With the trend to integrate a large number of cores on a single chip, Network-on-Chips (NoCs) are becoming more important for communication on System-on-Chips (SoCs). Designing high throughput and low latency on-chip networks with reasonable area overhead is one of the main technical challenges. This paper proposes an architecture of router with on-the-fly virtual channel (VC) allocation for hi...

An integrated optimization model was developed for the spatial distribution of agricultural crops in order to efficiently utilize agricultural water and land resources simultaneously. The model is based on the spatial distribution of crop suitability, spatial distribution of population density, and agricultural land use data. Multi-source remote sensing data are combined with constraints of opt...
