Assigning programming homework for programming courses is a significant learning activity used to improve students' programming ability. However, it is more challenging for instructors and TAs to assess the contents of programs written by students. For instance, they do not know the histories of program writings; they have to review source code manually; and even they cannot obtain statistic information...
Energy conservation is essential to wireless networks, particularly for third-generation (3G) and fourth-generation (4G) wireless systems, because high-speed data transmissions would rapidly exhaust the energy of a mobile station. This paper presents the details of energy-saving mechanisms for packet data services in two major standards, namely, the Third-Generation Partnership Project (3GPP) and...
Energy conservation is critical for third generation (3G) cellular systems. In particular, future high-speed packet data services are expected to exhaust the energy of a mobile station rapidly. In 3GPP systems, the radio resource is mainly controlled by the radio resource control (RRC). This paper quantifies the energy consumption and the reconnection ratio for 3GPP systems based on the RRC state...
The paper provides the comparison between WCDMA and cdma2000 of the impact of an inactivity timer on the energy consumption of a mobile station. Both simulation and analysis are utilized to investigate the impact of the inactivity timer and the performance comparison between WCDMA and cdma2000. The novel and practical models proposed analyze and quantify the energy consumption in the case of bursty...
