Because of wireless mobile networks characteristics

such as unstable performance

vulnerable to external disturbance

real-time scheduling in this environment is more challenging.Traditional scheduling algorithms generally ignore them.In this paper

we argue that fluctuation of network quality directly lead to the change of network delay

namely the time that task spending on network transmission changes.To solve the influence of network delay increases to the schedulability of a given set of tasks

a scheduling strategy is proposed to solve this unsatisfying change.Test results show that re-scheduling strategy improves the schedulability of a set of hybrid real-time tasks with unsatisfying network quality.
