We propose a simple but effective algorithm to formulate growable communication graphs that exhibit (i) fast information dissemination, (ii) high scalability with negligible performance degradation, and (iii) very small diameter and short average path length. In particular, we use Borel Cayley Graphs (BCGs) as base network topologies. Previously, we reported that BCGs are one of the fastest information...
Radiofrequency identification (RFID) technology has been adopted in various supply chain management applications because of its fast and low-cost ability to identify items uniquely. In this paper, we consider the integration of a wireless sensor network (WSN) with RFID to provide item-level inventory monitoring in retail stores. First, we present a basic formulation for RFID-based item-level inventory...
Development in micro-electronic-mechanical systems (MEMS), wireless communications and digital electronics recently have made it possible to develop small size, low-power, low-cost sensor devices. Such devices can integrate data processing, communications and sensing capabilities. A wireless sensor network (WSN) consists of a group of sensors, or nodes, linked by a wireless medium (infrared or radio...
