Second-generation (2G) mobile radio standards have not been designed with video communications in mind, although the employment of error-resilient, constant-bit-rate proprietary video codecs over these systems is realistic. The third-generation (3G) systems are capable of providing higher rates and better communications integrity in support of video(More)
— This paper investigates the practical issues related to the energy efficiency of a deployed wireless sensor network through the use of network simulations. The IEEE 802.11b standard is used as the communications technology and the dynamic source routing algorithm provides the mechanism for generating the communications routes from data sources to data(More)
—Spread adaptive quadrature amplitude modulated (AQAM) code-division multiple access (CDMA) is proposed as a powerful means of exploiting the time-variant channel capacity fluctuations of wireless channels. It is studied in comparison to variable spreading factor (VSF)-based techniques. These adaptive-rate transmission methods are compared in the context of(More)
