Abstract:
Energy consumption has become a major concern on wireless networks due to economical and environmental related issues. In order to cope with the increasing demand for wireless access, Mobile Network Operators (MNOs) have to massively deploy more wireless infrastructures. In the recent years, MNOs have faced the following dilemma in terms of energy wastage: how to increase the system capacity while at the same time saving energy? In this talk, I will present the main aspects behind the design of eco-friendly wireless networks with emphasis on how to reduce the energy wastage from the operational standpoint. Challenges and state-of-the art research topics in this area will be presented in-depth.

Abstract:
Contrary to General Ad Hoc Networks and Systems (GAHNS), which provide a one-size-fits-all basis for all kinds of applications, mobile opportunistic networks (OppNets) are a kind of Specialized Ad Hoc Networks and Systems (SAHNS), each of which is suitable as a foundation for a restricted class of applications or an individual application. It is expected that SAHNS, thanks to exploiting salient features of their application areas, will result in overcoming barriers that make GAHNS based solutions technically infeasible or inefficient. Oppnets constitute a new class of wireless ad hoc networks that allow a pre-designed seed Oppnet to grow into an expanded Oppnet by finding and using external devices and systems, which become their helpers. Significantly, these helpers can be employed opportunistically at low or even no cost. This talk will present a general introduction to Oppnets and their current state-of-the-art related research challenges, including those related to routing in such networks.
