Abstract
Low rate wireless sensor network has been used in industrial plant for certain production monitorings which have slow production rate. In the case of adding production line in the different building within one factory area, relay nodes are needed to increase monitoring coverage and connectivity among all nodes in the plant area. This paper presents the performance of relay node message scheduling scheme for extending monitoring area of production plan by using low rate wireless sensor network. The simulation results demonstrate that the distance and number of hop from certain relay nodes to the sink affect message end to end delay. Furthermore, increasing message rate generated by relay nodes also contributes in leveraging end to end delay of each message due to increasing queueing delay.
