 Game theoretic research for cloud computing
|
|---|
|
Cloud computing, one of the most prominent form of decentralized computer system,
is the composition of large scale of computational resources and distributed allocation rules.
Due to the nature of cloud computing, game theoretic concepts are considered suitable to approach designs of allocation and pricing.
Our lab applies game theory to construct mechanisms and algorithms for cloud computing system to efficiently allocate computation resources.
We establish auction mechanism and dynamic adjustment rules to improve performance. Moreover,
utilizing the pricing mechanism considering game theory, the decision criteria may rely on the price only,
and will be able to construct incentive compatible rules for the players.

Game theoretic research for wireless network
|
|---|
|
Game theoretic concepts have been widely adopted to solve problems exist in wireless networks nowadays.
In modern distributed protocols, nodes must decide ways to allocate the resources, and these decisions occasionally affect others.
Game theory then comes into play to generalize their interactions. In general, if a wireless communication problem involves more than one agent,
the problem is apt for being modeled as a game. Many microcosmic properties from the model can help the engineers to get insights of the systems.

 LTE-A & WiMAX standard
|
|---|
|
LTE-A and WiMAX are the candidates for the next-generation wireless communication system. Growing with the standard,
a stable and sound standardization process has been established for both the LTE-A and WiMAX.
We have a research team following the most recent development status of the two standards. In addition to attend the standardization meetings,
we also provide contribution documents to the standard. MAC layer concept and system design are our major focuses.
The system structure and MAC layer protocols are studied and discussed. If there are possible enhancements for the system,
we will propose the idea as contributions at the standard meeting.
Solid contributions and substantial system study records have been made for these two standards.

The main goal of vehicular networks is to provide Vehicle-to-Vehicle (V2V) and Vehicle-to-Roadside (V2R) communication to
improve driving safety and comfort. Our lab engages in the research of accessing the Internet via WiFi technology for
public transportation system. We aim to develop adaptive transmission strategies assisted with the accelerometer and GPS device.
Besides, we implement a testbed to conduct the experiments in the real-world subway station.
This system aims to improve the network efficiency as well as save the energy consumption.

 Cognitive Experimental Testbed with Software Defined Radio
|
|---|
|
Universal Software Radio Peripheral (USRP) is taken to turn general-purpose computer into a flexible Software Defined Radio (SDR) platform,
so that we can reconfigure digitized radio signal in the software domain. By the nature of flexibility,
a number of USRP nodes are included to construct a wireless network testbed,
so that it can facilitate a broad range of experimental research on a variety of application concepts.
The testbed bridges theoretical and simulation results with real-world feasibilities,
and currently developed as a Cognitive Radio (CR) platform to realize cross-layer cognitive protocol stacks.

Next-generation 802.11 WLAN
|
|---|
|
IEEE 802.11 WLAN standard is one of the most successful technologies for local wireless network.
It meets the general requirements of people's daily usage with relatively low cost equipments.
Our lab engages in the improvements enrolled into the next-generation IEEE 802.11 standards,
which focus on the requirements of advance features like ultra high throughput transmission and high-definition video broadcasting.
In addition, we also consider the possibility of cross-layer design in IEEE 802.11 networks. We are addressing several challenges in this area,
such as multi-user access control, TCP traffic-aware transmissions and content-aware packet prioritization.
The objective of our researches is to improve the next-generation IEEE 802.11 WLAN standard to catch up the growing needs of high-quality and
high-density communications.
