Information communication technology related vehicle services need to support location and the transmission of communication and traffic information between vehicles, or between vehicles and infrastructure. In particular, the technology for the measurement of the accurate location of a vehicle is dependent on location-determination technology like Global Positioning System, and this technology is very important for vehicle driving and location services. If, however, a vehicle is in a Global Positioning System radio-shadow area, neither a Global Positioning System nor a Differential Global Positioning System can accurately measure the corresponding location because of a high error rate caused by the shadowing intervention. Even an Inertial Measurement Unit could provide inaccurate location data due to sensor drift faults around corners and traffic-road speed dumps. Vehicles, therefore, need an absolute location to prevent the provision of inaccurate vehicle-location data that is due to radio-shadow areas and relational Inertial Measurement Unit positions. To achieve this, we assume that vehicle-to-infrastructure communication is possible between a vehicle and roadside unit in Vehicular Ad hoc Networks. We used iBeacon at the roadside unit and revised its Universally Unique Identifier so that it generates absolute Global Positioning System location data; that is, moving vehicles can receive absolute Global Positioning System data from the roadside unit-based iBeacon. We compared the proposed method with current Global Positioning System and Inertial Measurement Unit systems for the following two cases: one with a radio-shadow area and one without. We proved that the proposed method generates location data that are more accurate than those of the other methods.

Analytical assessment of the water energy resources in Ofu stream segments at Ofokopi, as one of the hydrologic regions of Kogi state, Nigeria was carried out. The principal focus was on the determination of the stream segments parameters of head, flow, power potentials and Environmental Impact Assessment (EIA). Two appropriate sites in close cascade were identified namely, Ofu I and Ofu II. Garmin GPSMAP 76S global positioning system was used to determine the gross hydraulic heads which gave 11.84 m and 8.60 m respectively. Power potentials of magnitude of 330 kW and 118.8 kW and annual energy generation of 2,890.80 MWhr and 1,040.69 MWhr respectively were estimated. The results of the EIA study yield negligible impact on the locality. The estimated power being in the mini hydroelectric schemes category, the identified sites could be developed to provide electric power for socio-economic transformation of the rural area.
