Comparison of TH-SS and DS-SS with sleeping protocol for LDR-UWB network

This paper addresses the performance evaluation of Time-Hopping (TH), Direct-Sequence (DS) and sleeping protocol in LDR-UWB (Low data rate-ultra-wideband) network in the view of energy consumption of node. The energy lifetime is one of the most challenging issues of low data rate UWB network. Ultra-wideband (UWB) radio systems operate using extremely short duration signalling pulses. Spread spectrum techniques for multiple access is commonly considered for such a systems. First, we describe about the energy consumption model based on TH-SS and DS-SS techniques. Secondly, we show the energy consumption analysis with the simulation results.
