Energy Efficient Interface Selection
in Heterogeneous wireless
networking

Heterogeneous networks
 In heterogeneous wireless networks, the mobile
terminal is assumed to be in the overlapping zone of
several networks.
 The radio signal strength (RSS) attributes are assumed
to be higher than the necessary thresholds to make
connectivity.
 The interface selection challenge is to determine the
most favorable trade-off among sevral metrics to select
the best network interface.

Problems& solutions
 Solving a network selection problem in which the terminals minimize
their energy consumptions with affordable QoS
 The problem can be modelled as dynamic game theory since we can
capture the dynamics of network selection at a bounded rationality.
The terminal changes network if it observed that its payoff is less than
average payoff of all users in the coverage area and evolutionary
equilibrium considered as a solution of the game
 Cooperation between different technologies to minimize overall
energy consumption of the system
 Trying to shutdown some of the base stations by cooperating between
this different technologies
