Abstract—Wireless sensor network in industrial environment
(denoted IWSN) has data delivery time constraint. Due to the
reactive routing and transmission collision, the data delivery time
in IWSN with CSMA/CA scheme is unpredictable. In this paper,
we utilize Time Division Multiple Access (denoted TDMA) MAC
to avoid data collision and to bound transmission delay. Consider
spatial reuse and data aggregation, a linear programming model
with simulated anneal algorithm are used to solve the TDMA slot
assignment problem in IWSN. Simulation results reveal excellent
sensing data collection time and system operation life time for
IWSN in the proposed slot assignment scheme.
