Today the traditional client-server network architecture is the predominant model in our network infrastructure. However, for the increasing amount
of \live" services such as TV and radio being digitalized and the growing
amount of user generated content, the centralized model can provide a poor
utilization of the available network resources. To efficiently support these
services we look towards the field of user cooperation. In order to create the
incentive for users to join the cooperation we must make the gain larger than
the expense. In this PhD I have suggested two central ways of achieving this.
1) I have suggested the use of network coding as a key-enabler for technology-
enabled cooperation. I refer to technology-enabled cooperation when we are
able to provide all participating entities in the network a better performance
by enabling user cooperation. In order to achieve this goal I apply network
coding, which from a theoretical point of view has the potential to make
our networks faster, energy-efficient, robust and more secure. In this PhD
I provide an experimental platform for network coding in order to evaluate
whether these theoretical merits may be transferred to practice. I provide
the initial development of systems and protocols and show that the potential
is there. However, I also find that network coding needs to be implemented
with care and protocols have to be designed with consideration to make use
of this novel technique. 2) The final aspect of this PhD investigates different
ways that cooperative models may be implemented to cover a wide range of
applications. This addresses the development of user cooperative protocols
and how we in Device To Device (D2D) communication may reward users
that contribute more to the network than they gain. In this area I suggest
the use of social-networks to allow payoff in different domains. In the future
this work could be expanded and built into cooperative protocols.
