- Description
- The evolution of wireless systems has led recently
to the deployment of cooperative network infrastructures where
networks based on different technologies cooperate together to
offer innovative services which the networks individually could not
offer. Cooperative network infrastructures are hybrid systems.
Examples of hybrid systems are already in use in areas as diverse
power systems and locomotion systems. It is very important to apply
efficient system management techniques to hybrid systems that
produce advantageous business case scenarios for each participating
system and efficient use of the available resources. In this paper,
scenarios are investigated where cooperation between an integrated
project (IP)-based broadcast network and an IP-based mobile
telecommunications network has the potential to allow services to
be provided to mobile users which would not be economical to offer
over either an IP-based broadcast network or an IP-based mobile
telecommunications network alone. The paper presents a novel
technique for determining which network to use to deliver such
services at a given point in time. The application of this
technique in appropriate scenarios has the potential to generate
additional income for both the IP-based broadcast network operator
and the IP-based mobile telecommunications network operator in an
infrastructure where the operators cooperate to offer innovative
services. The paper explains the construction of utility functions
for cooperative IP-based broadcast and mobile telecommunications
networks. These utility functions are then used to provide results
that enable the efficiency of the management of the network to be
assessed in terms of the utility volume generated by the innovative
services provided.
