Data Management in Mobile Computing and Sensor Networks

Overview

The main research interests of the group include Data Management for Systems and Networks, Information Systems, Energy-efficient Distributed Processing, ICT services for eHealth and Ambient Assisted Living. The group has a long term participation in research projects funded from national and international organizations, including the European Union and the Cyprus Research Foundation (RPF). More specifically, the group has participated in a number of IST projects related to mobile, wireless, sensor networks and distributed computing, such as SocialRobot, CoLiving, IPAC, CONET, mPower, LinkCare, HealthService24, and also RPF-funded projects like: PersonaWeb, FireWatch, MELCO, EKPAIDEION, DITIS.

Research Objectives

  • Communication - Synchronize reception/transmission windows [DISN07, MDM08, SENTIE09, INFOSYS11]
  • In-network Aggregation - Receive child results and compute final local Top-k results [MDM07, ICDE09, DAPD11]
  • Storage - Find the Top-k local results (sort, prune locally on flash-based storage) [DMSN09]
  • Mobility - Fault Tolerance through Data Replication [DMSN07, DAPD11]
  • Smartphones – efficient query routing trees (MDM11, IJCAI11)

Participating Projects

CONET, IPAC, FireWatch
