The future of wireless communications presents a scenario with many users sharing files or pictures or downlowding video. Social networks and real time
play a very relevant role in this scenario. Smartphones, tablets and laptop computers are common devices among people walking or travelling by car or
public transportation in cities or suburbs. The heterogeneity of the communication interfaces presents in such devices (GSM, HSPA+, LTE, 802.11,
Bluetooth, Zigbee) open new challenges related to the mobility and variety of interfaces. Heterogeneous wireless networks are characterized by the
coexistence of multiple technology and the mobility of the nodes which leads to frequent changes in the topology and possible connectivity issues. Hence
it is necessary the design and implementation of adaptive algorithms that allow the self-organization of the network in order to optimize the network
The main objective of this proposal is to offer a solution for the self-organized wireless connection of these devices with heterogeneous interfaces. In this
scenario we consider the presence of fix nodes as part of a network infrastructure with Interne connection, and also mobile nodes that can exchange
data with the fix nodes or with other mobile nodes through ad-hoc connections. This topology identified as Meshed Wireless Heterogeneous Network
presents a number of issues open for research with the aims of ensuring the network connectivity and provides robust connections in a network with
frequent changes. The adaptive algorithms for these networks must optimize the management of the users mobility and cooperate with the algorithms
that control the connectivity of ad-hoc nodes in such a way that changes have a minimal impact on the overall connectivity. A support for this cooperation
is available through the knowledge of the position of the nodes. It is also obvious that the routing protocol designed for such networks must easily and
quickly adapt to changes without the need to exchange large data amounts. The knowledge of the nodes position is also necessary in order to reach
these goals.
Energy-saving is today a key topic since in the case of wireless networks it represents a synergy of three objectives. First there is the reduction of energy
consumption and its impact on the environment. Second, less energy consumption leads to longer battery life, hence lighter devices for the same battery
duration or longer duration for the same wight, with obvious consequences on the usability. Third, longer battery life also involves more devices
connected at the same time, hence better connectivity. This project proposes applications of self-organizing networks to Green Networking. To this end
the self-organization algorithms that will be proposed will try to optimize the energy consumption among other metrics of the network performance. The
accessibility to handicapped people is also considered in the proposal and the longer battery econmy of energy consumption will also contribute to this
