An energy efficient vertical handover decision algorithm

As wireless communications evolve towards heterogeneousnetworks, mobile terminals have been enabled tohandover seamlessly from one network to another. At the sametime, the continuous increase in the terminal power consumptionhas resulted in an ever-decreasing battery lifetime. To that end,the network selection is expected to play a key role on howto minimize the energy consumption, and thus to extend theterminal lifetime. Hitherto, terminals select the network thatprovides the highest received power. However, it has been provedthat this solution does not provide the highest energy efficiency.Thus, this paper proposes an energy efficient vertical handoveralgorithm that selects the most energy efficient network thatminimizes the uplink power consumption. The performance of theproposed algorithm is evaluated through extensive simulationsand it is shown to achieve high energy efficiency gains comparedto the conventional approach.

Induced maritime accidents

Humanity system of life is highly supported by maritime transport when circa 8 thousand million people require about 8.800 million tons of merchandises by sea, going in some 105.000 merchant ships of over 100 GT, sailing every thinkable dangerous waters 365 days year 24 hours day. All that Enormous activity plus others different factors produce accidents, as is shown in an ascendant 1.7 rate related to ships lost with big number in life, cargoes losses, and pollution. That is why this study pretend to detect causes factors of maritime accidents, to try to reduce them, and with that targetin mind it was tested the new theory of Induced Maritime Accidents, crossing itsproposals with relevant sinister of different times and circumstances, as Andrea Doria, Torrey Canyon, Costa Concordia, among others. Those cases were re evaluated to establish the key points of such theory, as they are the Production Pressure, the Risk Homeostasis, technological advances and the rupture of safety margin. Cases studies gave as result the existence of referred key points, in a manner combined that the chain of events derived to the fatality, and more than that highlights the possibility that been suppressed to acceptable limits the production pressure or the risk homeostasis, a permissible safety margin were been maintained, avoiding catastrophe.
