Receiver Architectures for UWB-Based Transmit-Only Sensor Networks
Overview The authors are interested in designing a low-cost, Ultra-Wide-Band (UWB) sensor network that consists of a large number of Sensor Nodes (SNs), which sense the environment and transmit the resulting data via a wireless radio link to so-called Cluster Heads (CHs). The paper focuses on low-cost transmit-only SNs; the resulting uncoordinated multiuser-access causes packet collisions. To improve the robustness to packet collision, it propose two novel low-complexity noncoherent receiver architectures; the adaptive CH Receiver (CHR) that receives only packets whose signal strength is larger than an adaptive threshold; and; the switching CHR that allows the focus to be switched from a packet of a given SN to a packet from another SN with higher signal strength.
