During the great east Japan earthquake on March 11, 2011, a lot of ICT resources - telecom switching offices, optical fiber links, and so forth - were completely or partially damaged due to the tremor and the resultant tsunami. As a consequence, the demand for ICT services explosively increased, mainly because the people of the affected areas were trying(More)
Although topology control has received much attention in stationary sensor networks by effectively minimizing energy consumption, reducing interference, and shortening endto-end delay, the transience of mobile nodes in Mobile Ad hoc Networks (MANETs) renders topology control a great challenge. To circumvent the transitory nature of mobile nodes, k-edge(More)
Energy consumption and network connectivity are two of the important research issues that are yet to be resolved in mobile ad hoc networks (MANETs). As taken advantage of in static networks, reliable topology control algorithms are also considered to be a good approach for mobile networks. However, a more adequate evaluation of these algorithms regarding(More)
After disasters such as earthquakes and tsunamis, the network infrastructures might be extremely damaged or destroyed while Internet connection becomes much more necessary. Therefore, deploying networks in disaster areas has received much attention especially after the great earthquake in Japan on March 11, 2011. Among many kinds of networks, Wireless Mesh(More)
The Movable and Deployable Resource Unit (MDRU)-based network provides communication services in disaster struck areas where the lack of spectrum and energy resources is intensified due to the high demand from users and the power outages after a disaster. The MDRU-based network attempts to apply spectrumand energy-efficient methods to provide communications(More)
Recently, the issue of energy consumption of the user equipment (UEs) in the heterogeneous networks has rapidly become a focused research area of the entire telecommunications community. This issue is evidently critical because the energy consumption of the UEs can severely degrade their already limited battery capacity. In this article, we consider a(More)
