With the access of a myriad of smart handheld devices in cellular networks, mobile crowdsourcing becomes increasingly popular, which can leverage omnipresent mobile devices to promote the complicated crowdsourcing tasks.
Device-to-device (D2D) communication is highly desired in mobile crowdsourcing when cellular communications are costly.
The D2D cellular network is more preferable for mobile crowdsourcing than conventional cellular network.
Therefore, this paper addresses the channel access and power control problem in the D2D underlaid cellular networks.
We propose a novel semidistributed network-assisted power and a channel access control scheme for D2D user equipment (DUE) pieces.
It can control the interference from DUE pieces to the cellular user accurately and has low information feedback overhead.
For the proposed scheme, the stochastic geometry tool is employed and analytic expressions are derived for the coverage probabilities of both the cellular link and D2D links.
We analyze the impact of key system parameters on the proposed scheme.
The Pareto optimal access threshold maximizing the total area spectral efficiency is obtained.
Unlike the existing works, the performances of the cellular link and D2D links are both considered.
Simulation results show that the proposed method can improve the total area spectral efficiency significantly compared to existing schemes.
