“…In addition, ANCM approaches need devices to be equipped with strong sensing ability, which is usually seriously constrained in field devices. Therefore, methods complying with the ANCM concept so far have been applied for solving coexistence problems in public areas [7]- [9], but are not ready, or are still controversial, for industrial automation applications [10]. A list of reasons in this regard has been discussed in works [6], [11], e.g., constrained processing ability of sensor devices, battery limitations, etc.…”

The future manufacturing environment is foreseen to be increasingly diverse with multi-vendor industrial wireless devices deployed in the same geographical area. Thus, effective medium resource sharing mechanisms are urgently needed to enable the coexistence of those heterogeneous industrial wireless sensor networks (IWSNs). To accommodate such heterogeneity, this paper proposes a collaborative scheduling algorithm (CSA) for coordinating the activation of each coexisting IWSN while guaranteeing their respective real-time communication requirements. Specifically, the proposed CSA is able to help determine a unique data transmission instantance for each network node that periodically generates time-sensitive data, through which timely data delivery is guaranteed without the interference of each other. INDEX TERMS Coexistence, industrial wireless sensor network, heterogeneity, real-time communication.

This study deals with implementation and verification of the cyclostationary feature detector suitable for DVB-T signals. A new decision statistic has been proposed for a multi-cycle detector. Computer simulations have shown that it outperforms decision statistics of similar complexity in terms of the probability of missed detection for fixed probability of false alarm. The detector utilising the new decision statistic has been implemented in the experimental setup and used for detection of the digital television signal. The measurement results have been compared against the results obtained from the computer simulations.

Efficient Signal Detection Techniques in TV White Space using Cognitive Radio

TV white space is the unused TV spectrum which can be used by secondary users to solve the problem of spectrum scarcity and to increase its efficiency. All DTT signals use OFDM, but they many employ different sets of pilot carriers, guard intervals and symbol sizes. The proposed algorithms aim to detect CR signal with reasonable detection performance in TV white space. First algorithm is based on cyclo-stationary feature detection and second algorithm is based on energy detection.
