“…A number of MAC protocols are proposed for both intra-cluster communication (between CH and CM) and inter-cluster communication (between CHs) [4] [5]. The energy efficiency of the CMs is mostly affected by an intra-cluster MAC protocol, which manages the CMs access to the shared medium and tries to ensure that no collisions occur [6].…”

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.
