Improving Goodput in LoRa Concurrent Transmission

This paper aims to improve the energy efficiency of LoRa by enabling LoRa nodes to operate in a downclocked 'light sleep' mode for packet reception.

Energy Saving in LoRa

This paper aims to improve the energy efficiency of LoRa by enabling LoRa nodes to operate in a downclocked 'light sleep' mode for packet reception.

Parallel Decoding in LoRaWANs

This project presents a novel communication paradigm that enables parallel demodulation of colliding LoRa transmissions.

Out-of-Band Communication in Wi-Fi for Smartphone Energy Saving

In this project, we propose a new power-saving strategy for screen-off Wi-Fi communications.

ZigBee and Wi-Fi Co-existence

In this work, we design a simple yet effective error recovery code that uses XOR code to minimize delay and uses RSSI-hinted approach to detect in-packet corruptions without CRC.

Bulk Data Dissemination in Wireless Sensor Networks

This project proposes a novel sender impact metric which jointly exploits link quality and spatial link diversity to calculate the gain/cost ratio of the sender candidates.

Reprogramming in Wireless Sensor Networks

We propose ReLog which consists of a programming language, a compiler, and a virtual machine to support reprogramming in wireless sensor networks.

Opportunistic Routing in Heterogenous Duty-cycled Wireless Sensor Networks

This paper aims to improve the energy efficiency of LoRa by enabling LoRa nodes to operate in a downclocked 'light sleep' mode for packet reception.
