[Jerry]

Please take time to attend the next faculty candidate presentation and meet with the candidate afteward. You maybe taking courses from anyone of our candidates so this is your oppotunity to voice your opinion.

Quality of Service Constraint Design in Wireless Sensor Networks


Abstract

A Wireless Sensor Network (WSN) is consisting of a collection of small sensors with limited sensing, computation, and wireless communications capabilities. It can be used to sense/monitor the physical environmental changes, and convert the sensed event to a new form of network data according to various application requirements.

On the one hand, WSNs have the advantages of self-organization, cost effectiveness, ease of deployment, and are widely used in a broad range of military and civil application scenarios, such as intrusion detection, disaster relief, target tracking, and patient monitoring. In a word, WSNs provide the foundations for virtual reality. On the other hand, WSNs have the limitations of low date rate, limited computing power, small sensing range, small transmission range, and limited battery power. Due to this, there exist fundamental limits in the operation of WSNs. It is imperative to quantify the limitations and identify the tradeoffs so as to provide guidelines in building a WSN with satisfactory Quality of Service (QoS).

Our aim is to characterize the fundamental limits of WSN, establish the relationships between network parameters and the WSN QoS with respect to various application requirements. The topics will be covered in this presentation include QoS constraint design in regular WSNs, random WSNs, and application-specific WSNs. The results can be used as a guideline for selecting critical network parameters, so as to provide optimal or application-specific QoS and maximum deployment efficiency, for various WSN application scenarios.
