This research investigates the feasibility of applying the wireless transmission of PDA or GPRS as a communication tool to inspection engineers. Application of such tools at construction job-sites can help all inspection engineers make a better construction management. Based on the development, all kinds of information regarding the construction activities such as standard specifications, figures,...
In recent years, wireless and mobile communication systems become increasingly popular. The demand for mobile communication has thus made the industry put more efforts towards designing new-generation systems. One of the important issues in mobile-phone communications is about the static channel assignment problem (SCAP). Although many techniques have been proposed for SCAP, a challenge for the cellular...
In wireless ad hoc networks, designing energy-efficient routing protocols is a major issue since mobile hosts are energy-limited. In this paper, we propose an energy saving cache-based routing protocol (ESCR) to address this issue. In the proposed routing protocol, when the energy of the grid header is not sufficient for data transmission, new grid header is elected directly by ESCR without the traditional...
