description

Wake-up Radio (WuR)-enabled wireless personal area networks (WPANs) are more popular over conventional WPANs thanks to WuR's on-demand transmission feature and overwhelming energy consumption superiority. In a WuRenabled WPAN, overhearing occurs when a wake-up receiver decodes and validates the address of a wake-up call which is not intended to it. However, such overhearing consumes a portion of the required reception energy for unintended nodes. To diminish overhearing thus conserve total reception energy in a network, we propose a bit-by-bit address decoding (BBAD) scheme and compare it with another addressing scheme for WuR that uses a micro-controller unit to decode and match the whole sequence of an address. Instead of decoding and validating a complete address at a time, BBAD decodes and matches an address in a bit- by-bit manner. We implement both address decoding schemes through a WuR testbed. Furthermore, we develop a framework based on M/G/1 and assess the performance of the WuR-enabled WPANs through both analysis and simulations.
