Figure 1: CPS integrates cyber world and real world.

Figure 2: Data transmission using WNC technique

The wireless world never stops growing. This results many people are connected wirelessly with mobile devices that allows them to keep up with the upto- date information. The next largest breakthrough will be the sensory swarm, which enables more pervasive wireless networking and the vast deployment of sensors and actuators. The sensory swarm gives rise to the emergence of cyber-physical systems concept, which comprises the information-gathering network that would feed the massive information technology core with mountains of raw data to be processed and spun back out to us on our portable computing devices and laptops in a timely manner. These wirelessly sensors and actuators will be quite complex, requiring self-contained radio frequency, digital circuitry, clocks, and processing engines. Thus, it inspires architectures that will afford an order-of-magnitude improvement in efficiency and resource management. Our disciplinary research focuses on cyber-physical systems, sensor network system and wireless communications.

1. Cyber-Physical Systems (CPS)

CPS contributes to safety, efficiency, comfort and human health, and help solving key challenges of our society, such as the ageing population, limited resources, mobility, or the shift towards renewable energies. One example of CPS applications is a smart home automation for comfort control. In smart homes, appliances, devices, sensors, and actuators are expected to assist people live on their own comfortable, relax, restful, and pleasant.

2. Wireless Network Coding (WNC)

WNC refers to a technique where a wireless device is allowed to generate output data by mixing its received data. The unique characteristics of wireless medium renders WNC particularly advantageous, e.g., this technique can be used to achieve the minimum energy-per-bit for multicasting in a multihop wireless networks. In recent, this technique has been developed into a data link layer. The WNC engine in the data link layer can opportunistically mix the outgoing packets to reduce the transmissions in the air.
