This paper presents the Load-Haul-Dump (LHD) remote monitoring and management system based on delay/disruption tolerant network, which aims to manage a fleet to ensure reliable haulage operations at points on construction in hard environment. The fleet means the complement of construction machines, dump trucks, and workers that are working together. Connectivity on the Internet primarily relies on wired links, including the wired telephone network and cellular phone network. When constructing a field network, however, we often face a particular communication region outside of the Internet and a transmission of data delayed. This paper gives arguments about some of the ways to handle data communication that suffers delay or disruption in such a hard environment. In addition, are reported two case studies on the deployment of the LHD remote monitoring and management system to accommodate mobility of data, in order to manage construction machines and dump trucks in a haul work.

Keywords: LHD, remote monitoring on real time basis, event detection, and delay/disruption-tolerant
