Mobile Edge Computing(MEC) server on small cell base station is one of the leading ideas in 5G ultra-dense networks which plays an important role in the popularization of innovative traffic-intensive applications and overcomes the abridgement of resource constraints mobile devices. Existing researches mostly focus on single-tier BS scenario (SBS-MEC offloading) while ignoring SBS coalitions and remote servers. However, the distinct cell has confined computing resource to handle the massive amount of workload. In the present work, collaborative task offloading scheme is proposed in order to acquire better performances, as the scheme is hypothesized to handle a huge number of incoming user requests, and reduce the time consumption as well as the number of failed tasks. The simulation results show that it can reduce the average task duration at almost 17.6% and average task failure at approximately 19.1%, compared to the single-tier BS scenario.
