title = "Dynamic spectrum utilization in ad hoc networks",
abstract = "This paper considers the problem of adaptively utilizing temporal and spatial {"}holes{"} in spectrum for communications. In addition to improving spectrum utilization, it also enables the rapid deployment of military assets into remote areas where the spectrum assignment may differ. The problem raises issues related to modelling available spectrum, link establishment, and methods to employ the holes. In a tactical environment, evading interception and detection is critical; hence coding and steganographic techniques are applied. A simulation study investigates trade-offs between an automatic repeat request (ARQ) scheme and a scheme employing erasure codes in predicted holes for high packet loss rates.",
