“…In our earlier work, we proposed a BCD-like contention resolution algorithm with tone-based signalling in TDMA-based WSNs [15]. In [16] we proposed STAR-TONE MAC protocol, with bit mapbinary countdown (BM-BCD) CRM, which modifies the baseline BCD scheme in a following way. Firstly, STAR-TONE involves CH actively into the contention resolution process, which eliminates the hidden terminal problem.…”

A reliable and energy-efficient contention resolution mechanism (CRM) is a crucial component of MAC protocols for wireless sensor networks (WSNs). Among a number of CRM proposals, CRMs based on exchanging short signal tones between competing nodes have recently drawn attention due to their promise of collisionfreedom and energy-efficiency. However, the basic assumption of these protocols, i.e. the possibility to reliably detect the presence/absence of a signal tone in case of simultaneous transmissions from multiple nodes, has not yet been confirmed. In this paper a technique for signal tone generation/detection is presented, which uses only standard features of off-the-shelf RF transmitters. Furthermore, the results of an experimental validation carried out in a real testbed are presented which demonstrates a high accuracy of signal tone detection in the presence of multiple simultaneous transmissions.
