چکیده
This paper presents the research on application of wireless sensor networks (WSNs) in wind power generation system and highlights an important issue associated with the deadline for the delivery of messages among nodes based on IEEE 802.15.4E standard. Due to the limits of standard and the power system application requirements, this research proposes a smart GTS (S-GTS) allocation algorithm which is based on Urgent/Important Matrix. This proposed algorithm promotes the utilization of CFP in a superframe, which can reach 94.64%. And over seven GTSs can be allocated in a superframe, there are only seven GTSs can be used in the standard. Additionally, this paper proves the value of BO and SO upper bound is 6 for the WSN application in power system. Moreover, when BO = SO =2, the network delay of S-GTS is 13.44ms, which perform better than 16-time-slot mechanism (58.08ms) and i-GAME mechanism (61.44 ms).
