Marine pollution is a worldwide problem that affects the water environment, the economy and even the human health. Depending on the type of pollutant, it is required different techniques to remove it. In order to avoid higher impact and damage in the affected area, the most important action is to perform a quick detection and determine where the pollution stain or spill is. Due to its fast dispersion, the case of oil spills is especially critic because they are almost impossible to clean if the decontamination tasks do not start immediately. For this reason, in this paper we propose a system based on a smart algorithm which is able to detect, track and locate pollution stains, such as oil spills. The system is composed by wireless nodes that are able to move towards the end of the stain seeking its edge. Nodes use IEEE 802.15.4 and the Global Position System (GPS), to communicate the final position of the stain. Finally, we tested the operation of our system, using the routing protocols Ad hoc On-Demand Distance Vector (AODV) and Destination-Sequenced Distance Vector (DSDV). Our results show that it presents better performance when using reactive protocols.

The number of home devices integrating new technologies is continuously increasing. These advances allow us to improve our daily routines. In addition, the improvement in network infrastructure and the development of smart phones and mobile devices allow us access from any place to any of our systems over the Internet. Bearing in mind this idea, we have developed a low-cost ad hoc protocol based on Bluetooth technology that allows us to control all our home appliances and monitor the power consumption of our homes. Our proposal is based on an Android application installed on a mobile device which acts as server. The application allows users to program the various appliances. It is also able to check the status of the appliance, as well as controlling the power consumption of the house and its cost. The system is equipped with a smart algorithm able to manage all appliances and decide which ones should work as a function of various criteria such as time of day or power consumption. Finally, the system is able to detect faults in water and electricity supply for acting accordingly. All data received and sent by the server are stored in a database which the system can check and compare to make their own decisions.
