This paper investigates and undertakes simulation-based comparison of on-demand routing protocols in multi ad hoc networks. First, it investigates the factors affecting the performance criteria and working architecture of ad hoc on-demand distance vector (AODV), dynamic source routing (DSR) and temporally ordered routing algorithm (TORA). Second, it(More)
This cross-sectional study explored the extent and impact of mobile device-based Sleep Time-Related Information and Communication Technology (STRICT) use among American adolescents (N = 3139, 49.3% female, mean age = 13.3 years). Nearly 62% used STRICT after bedtime, 56.7% texted/tweeted/messaged in bed, and 20.8% awoke to texts. STRICT use was associated(More)
One of the advantages of the Discrete Wavelet Transform (DWT) compared to Fourier Transform (e.g. Discrete Cosine Transform DCT) is its ability to provide both spatial and frequency localization of image energy. However, WT coefficients, like DCT coefficients, are defined by magnitude as well as sign. While algorithms exist for the coding of wavelet(More)
