Device Cooperative Conflict Detection and Resolution Based on Time Estimate
In the device cooperative system, the cooperative tasks have device exclusivity. Therefore, the concurrent execution of multi-tasks leads to the device conflicts. One of the key research challenges in device cooperation is the detection and resolution of the device conflicts. Taking the large scale lighting device cooperative system as research background, this paper proposes a mechanism of conflict detection and resolution based on time estimate, which consists of two stages: during the task reservation stage, the device reservation mechanism based on time estimate and equivalent process replacement method are presented for the conflict detection and prevention; during the task execution stage, the exception handling mode is applied for the conflict resolution. Experimental results show the effectiveness of the proposed mechanism.
