Abstract
This paper presents investigation on application of wireless sensor networks (WSNs) in wind power generation systems
and highlights an important issue associated with the deadline for the delivery of messages among nodes based on the IEEE
802.15.4E standard. Owing to the limits of standard and the power system application requirements, this research proposes a
smart guaranteed time slot (S-GTS) allocation algorithm which is based on the urgent/important matrix. This proposed
algorithm promotes the utilisation of contention free period in a superframe. Besides, over seven GTSs can be allocated in a
superframe, there are only seven GTSs that can be used in the standard. In addition, this study proves the value of BO and
SO upper bound is 6 for the WSN application in power systems. Moreover, the network delay of S-GTS performs better than
the 16-time-slot mechanism and i-GAME mechanism.
