One of the main aspects that affect the performance of hybrid ad hoc networks is the discovery and selection of Internet gateways. Similar to conventional ad hoc route discovery, this procedure could be accomplished employing three different strategies: proactive, reactive and hybrid. In the proactive gateway discovery, the gateway periodically generates(More)
In order to extend the use of Mobile ad hoc networks (MANET) to commercial applications, it is necessary to provide a mechanism to integrate this kind of networks into the Internet. In this way, MANETs could be utilized in visiting theme parks, commercial centers and military scenarios. The interconnection of MANETs and the Internet is supported by a(More)
Mobile users are expected to demand access to the Internet anywhere and anytime. In a MANET context, a device which is about to connect to external hosts needs the route to the element which communicates the MANET with the Internet. This element is the Internet Gateway. To inform about its presence as well as about some configuration parameters, the Gateway(More)
Developing generic competences in bachelor degrees is not an easy task. In order to get a successful result, all actors in the teaching-learning process must agree in several topics, as the definition of each competence or the best approach for learning and evaluation. For this reason, the point of view of the students should be considered. This paper(More)
—When a wireless node in an ad hoc network needs Internet access, it must select one gateway from the information sent in the Modified Router Advertisement (MRA) messages. In this paper, we propose an adaptive gateway discovery scheme that dynamically adjusts the frequency of MRA messages. This tuning is related to the mobility of the ad hoc network. The(More)
