DESCRIPTION:Wireless Sensor Networks (WSNs) are now used for more than jus
 t basic delay tolerant data collection applications. WSNs are increasingly
  employed for complex process automation and control applications. In such
  scenarios\, the WSN is part of a control loop\, and predictable network p
 erformance\, in terms of message transfer delay and reliability\, is requi
 red. However\, existing WSNs are designed to conserve energy and not to su
 pport timely data delivery. Thus\, a new approach for building WSNs is nec
 essary which takes strict performance requirements into consideration.\n\n
 In this talk I will outline challenges we have to overcome in order to bui
 ld efficient WSNs with predictable and stable network performance. Further
 more\, I will detail solutions that enable us to overcome some of these ch
 allenges. To support time-critical data delivery in WSNs\, new tools\, pro
 tocols and software components are required. It must be possible to design
  a network such that it provides the required performance when deployed. T
 hus\, tools are required that can support network planning. Software compo
 nents are necessary that ensure timely processing. Communication protocols
  are needed that can provide stable performance in environments with fluct
 uating channel quality. Finally\, tools for performance monitoring of a de
 ployed network are required. These performance debugging tools are require
 d to isolate faults in case deadlines are missed.\n\nShort bio:\nDr Utz Ro
 edig is a Lecturer in the School of Computing and Communications at Lancas
 ter University\, UK. He pursues research in the area of networked embedded
  systems and in the particular domain of WSNs. He is author of over 40 pee
 r-reviewed publications in this research field. He was Conference and TPC 
 Co-Chair for conferences and workshops such as EWSN 2009 and SenseApp 2007
 . He serves as TPC member for many leading sensor network conferences incl
 uding EWSN\, IPSN and SenSys. Dr Roedig is currently involved in the EU FP
 7 projects GINSENG and WISEBED. GINSENG investigates the deployment of tim
 e-critical WSNs. WISEBED aims to construct an infrastructure of interconne
 cted WSN testbeds for research purposes.\n
