Two-dimensional (2D) communication is a novel physical communication form that utilizes the surface as a communication medium to provide both data and power transmission service to the sensor devices placed on the surface's top. In previous works, we developed 2D communication systems that utilize separated channels for data and power transmission. Though this assignment of different channels can...
The two-dimensional communication system (2DCS) is a novel technology that allows the surface physical as a communication medium for providing simultaneous power supply and data transmission to any device. However, how to carry out simultaneous power supply and data transmission in an efficient manner is still an open issue for 2DCS. In this paper, we propose a concurrent power supply and data transmission...
The goal of this study is to define a scheme for fast and accurate medium access control (MAC) in distributed power-controlled wireless networks. The system model assumes (i) arbitrary topologies, (ii) arbitrary call arrival rates, (iii) multiple links transmitting simultaneously over shared interference-limited channels, and (iv) transmitters updating their powers to maintain a predefined signal-to-interference...
ZigBee technology has become the standard of choice among other wireless technologies by providing efficient low-power connectivity while allowing for a large number of devices to be part of a single network. The security of the ZigBee communication becomes the important role. But, ZigBee cannot provide sufficient security when large sensor networks appeared. To address these limitations, we propose...
The Optical Integrative Switching (OIS) networks supporting 3G is proposed in this paper. In this OIS networks which supporting 3G, four different classes of service traffic is introduced to meet the demand of 3G. We construct architecture of WDM OIS ring network which utilizes M-token signaling scheme. In the M-token access protocol, the token can be captured according to the service class. The performance...
Wireless sensor networks are envisioned to support autonomous and spontaneous networking for a wide range of applications. Node addresses are essential to enable successful communication in sensor networks. This paper presents a novel address autoconfiguration scheme to automatically configure network-layer and MAC-layer addresses for sensor nodes with energy efficiency and fault tolerance. Computer...
