Abstract:
|
This paper addresses the trade-off between latency and energy consumption in wireless application offloading in a multiuser set-up. The advantages of carrying out offloading versus executing an application locally at the user terminal
depend on multiple parameters. This paper evaluates the impact
that the transmission rate and the load of the system have on the
quality of service experienced by the users as well as on the
energy saving that the users get from doing offloading. Based on
this evaluation, the paper proposes a method to select the uplink
data rate that minimizes the latency experienced by the user
given a target energy saving with respect to the case of no
offloading. The result depends on the channels conditions, the
system load, the application parameters, and the energy
consumption features of the terminal. The method is presented
firstly for flat fading channels and secondly for non-flat fading
channels. |
