Mesh HDR WPAN resource allocation optimization approaches

Abstract EN

In the multihop IEEE 802.15.5 networks, all the devices compete to the resources of a shared superframe.

In order to distribute these resources in a fair and satisfactory manner among the competing devices, we propose a distributed optimization framework for resource allocation scheme in an IEEE 802.15.5 hop-1.

For this purpose, we introduce in this paper a suite of optimization problems for the hop-1 IEEE 802.15.5 resource allocation to optimize fairness and satisfaction without exceeding the superframe size and respecting the demanded channel time size sent by the requesting devices.

Simulation results studied and compared the satisfaction factor and fairness index of the different proposed optimization problems.

Consequently, a trade-off between satisfaction and fairness should be conducted for choosing the optimal solution.
