This paper investigates the problem of placement of data aggregation points (DAPs) in advanced metering infrastructures (AMIs). The specific constraints are that DAPs are to be located on utility poles and that communication is done over wireless links. While the resulting optimization problem is an integer program, we propose to adapt the K-means algorithm to obtain an efficient and less-complex method to solve the DAP placement problem. Simulations of the developed optimization method illustrate the effects of smart-meter density and communication range on the selection of DAP locations.
Abstract-In this paper we address the problem of spatialreuse scheduling for underwater acoustic communication (UWAC) networks that support high traffic broadcast communication and require robustness to inaccurate topology information. To this end, we derive a broadcast scheduling algorithm that combines topology-transparent and topology-dependent scheduling methodologies to achieve high-throughput in static and dynamic topology scenarios. While we focus on scheduling in UWAC networks, our approach can also be adopted for broadcast scheduling for radio ad-hoc network if robustness to topology uncertainties is desired. Simulation results for typical UWAC scenarios demonstrate that our protocol achieves high throughput and provides robustness to outdated topology information in dynamic topologies.Index Terms-Underwater acoustic communication (UWAC), broadcast scheduling problem (BSP), spatial-reuse scheduling, topology-transparent scheduling.

Type-2 systems has been becoming the focus of research in the field of fuzzy logic in recent years. Comparing with type-1 systems, type-2 fuzzy systems are more complex and relatively more difficult to understand and implement. We developed an interactive graphical user interface (GUI) based toolbox, MFLS tool, for interval type-2 fuzzy logic system. This paper presents MFLS toolbox. Moreover, the versatility of the software is demonstrated via an prediction problem.
