This paper presents a new routing protocol for opportunistic networks based on sociological movement model. In this movement model, the mobile nodes have the tendency to visit fixed places frequently. Our approach recognizes the encounter places, called hubs, and employs them as base elements for the routing procedure. Nodes visiting frequently two or more hubs are considered carriers and are used...
This work presents a method of coordinating static ground sensors with Unmanned Aerial Vehicles using coordinators. The ground wireless sensors are responsible for the primary detection of an event (e.g. intrusion in the monitored area). After the initial detection, a suitable UAV, equipped with high quality surveillance devices, should be designed inspect the event's area. A method combining a geographic...
This paper presents an algorithm to allocate suitable nodes of a Wireless Sensor Network (WSN) to accomplish a given task (called mission). This algorithm is part of the Grubmi middleware. A mission is inserted in an arbitrary point of the network, being disseminated to all nodes by the middleware. Then, a suitable set of nodes should be selected to execute the jobs described by the mission. The network...
