Speed, Reliability and Energy Efficiency of HashSlot Communication in WSN Based Localization Systems.

Precise localization of mobile objects is a common problem in WSN research for which various approaches exist. However, apart from technical aspects and the location estimation itself, speed, reliability and energy efficiency are central but barely addressed aspects within such systems. We will point out, that the applied wireless communication affects these aspects significantly before comparing some well-known and commonly used radio protocols to the self-organizing HashSlot approach which was optimized for efficiency in wireless information aggregation. Besides some theoretical considerations, this paper presents practical results from a real-world testbed based on the ultrasound localization system SNoW Bat. [ABSTRACT FROM AUTHOR]
