In statistical delay bounded Qos with a probability of threshold, the tasks are planned to be completed before a deadline. While implementing a statistical approach, it is first required to consider the challenges.

1 i) Correlation between statistical delay and task offloading: The first challenge is defining a correlation between the statistical delay requirement and task offloading. Under a constrained communication and computation resource, quantifying the correlation is achieved.

2 ii) The low complexity - Second challenge for implementing statistical delay bounded QoS is to provide a holistic solution with low time complexity. Complexity is due to heterogeneous users in terms of computing capabilities and task requests [32]. Holistic task offloading algorithm considerations are discussed below.
