Modeling In vivo Wireless Path Loss

open access: yes, 2014
Our long-term research goal is to model the in vivo wireless channel. As a first step towards this goal, in this paper we performed in vivo path loss measurements at 2.4GHz and make a comparison with free space path loss.

Mesh-under cluster-based routing protocol for IEEE 802.15.4 sensornetwork [PDF]

open access: yes, 2014
The radio duty cycle (RDC) of wireless sensor nodes can be considered as a crucial factor that determines the wireless sensor network (WSN) lifetime and its service availability. Clustering would be a preferable solution to minimize node radio duty cycle

Power-Based Direction-of-Arrival Estimation Using a Single Multi-Mode Antenna

open access: yes, 2017
Phased antenna arrays are widely used for direction-of-arrival (DoA) estimation. For low-cost applications, signal power or received signal strength indicator (RSSI) based approaches can be an alternative. However, they usually require multiple antennas,

DC-Informative Joint Color-Frequency Modulation for Visible Light Communications

open access: yes, 2015
In this paper, we consider the problem of constellation design for a visible light communication (VLC) system using red/green/blue light-emitting diodes (RGB LED), and propose a method termed DC-informative joint color-frequency modulation (DCI-JCFM ...
