Title: AACT: Application-Aware Cooperative Time Allocation for Internet of Things,
Abstract: As the number of Internet of Things (IoT) devices keeps increasing, data is
required to be communicated and processed by these devices at unprecedented
rates. Cooperation among wireless devices by exploiting Device-to-Device (D2D)
connections is promising, where aggregated resources in a cooperative setup can
be utilized by all devices, which would increase the total utility of the
setup. In this paper, we focus on the resource allocation problem for
cooperating IoT devices with multiple heterogeneous applications. In
particular, we develop Application-Aware Cooperative Time allocation (AACT)
framework, which optimizes the time that each application utilizes the
aggregated system resources by taking into account heterogeneous device
constraints and application requirements. AACT is grounded on the concept of
Rolling Horizon Control (RHC) where decisions are made by iteratively solving a
convex optimization problem over a moving control window of estimated system
parameters. The simulation results demonstrate significant performance gains.
