Crowdsourcing in cellular networks, wherein smartphone users upload sensing data pieces using their smartphones to a service provider, has become popular. However, a shortage of cellular uplink frequency resources prevents a service provider from collecting large data with reasonable costs. Incorporating collaborative upload, wherein representatives upload their sensing data pieces as well as those of others, is a promising solution. A key to make a business based on such crowdsourcing, which we call collaborative crowdsourcing, successful is how to motivate smartphone users to become representatives. In this paper, we propose a novel rewarding scheme for the users to advocate collaborative crowdsourcing.
