In order to resolve the scalability and handover performance issues of existing approaches, we propose a scalable mobility platform which is based on the hierarchical Distributed Hash Table (HDHT), referred to here as MoHiD, to provide host mobility through a DHT. In MoHiD, the location information of the hosts is stored in the HDHT running on the MoHiD Access Router to provide mobility. In the...

A mathematical model can be considered as an approximate reconstruction of a real phenomenon. All parameterizations and approximations used in models lead to deviations of the model results from nature. It is an accepted requirement that a numerical model of estuarine hydrodynamics should be verified, calibrated and validated before used in a practical application. However, the procedures to pe...

In order to improve the accuracy of particle tracking prediction techniques near Korean Strait, this study compared and analyzed a model based on seawater flow numerical machine learning using field observation data. The data used in were surface drifter buoy movement trajectory observed Korea by (linear regression, decision tree) tide wind from three stations (Gageo Island, Geoje Gyoboncho), p...

Abstract Sea level rise is a worldwide concern as high percentage of the population located in coastal areas. The focus this study impact sea Guadiana Estuary, an estuary Iberian Peninsula formed at interface River and Gulf Cadiz. Estuaries will be impacted by these transitional environments host highly diverse complex marine ecosystems. major consequences are intrusion salt from into fresh wat...

An integrated system named METEOMOHID, developed by MeteoGalicia in the first stage of the Prestige accident in November 2002 was used successfully in an operational form to support decision making and assist in recovering tasks. Afterwards, METEOMOHID has been enhanced with the aim of developing an operational oceanography system to be used in the NW of the Iberian Peninsula. The METEOMOHID sy...

The success of an irrigation decision support system (DSS) much depends on the reliability information provided to farmers. Remote sensing data can expectably help validate that at field scale. In this study, MOHID-Land model, core engine IrrigaSys DSS, was used simulate soil water balance in irrigated vineyard located southern Portugal during three growing seasons. Modeled actual basal crop co...

Two unusual circulation patterns were measured in the Ria of Pontevedra (NW Spain). The first one showed a positive two layered tidal pattern with water leaving the estuary through surface layers and entering it through the bottom ones. This unusual pattern is observed to depend on the particular summer stratification conditions, caused by upwelling events and solar radiation, and on the presen...
