Extending Monitoring Area of Production Plant Using Synchronized Relay Node Message Scheduling

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

Performance Analysis of Mobility Impact on IEEE 802.11ah Standard with Traffic Pattern Scheme

Internet of Things (IOT) offers a new dimension of technology and information where connectivity is available anywhere, anytime, and for any purpose. IEEE 802.11 Wireless Local Area Network group is a standard that developed to answer the needs of wireless communication technology (WI-Fi). Recently, IEEE 802.11 working group released the 802.11ah technology or Wi-Fi HaLow as a Wi-fi standard. This standard works on the 1 GHz frequency band with a broader coverage area, massive device and the energy efficiency issues. This research addresses, the influence of Random Walk, Gauss-Markov, and Random Waypoint mobility model on 802.11ah with different traffic pattern scheme are analyzed. The design of the simulation system is done by changing of node density. Based on the result, it can be concluded that the overall performance of the network with all of the parameter scenarios is decreasing along with increasing the Stations. In the node density scenario, the Random Waypoint mobility model has the best performance with an average delay is about 0.65805 s, throughput is about 0.53811Mbps, PDR is about 96.75%, and energy consumption is about 5.2530 Joule

This research addresses, the influence of Doppler Effect using Random Waypoint mobility model on 802.11ah with different user speed are analyzed. The design of the simulation system is done by changing user speed and MCS. Based on the result, it can be concluded that the overall performance of the network with all of the parameter scenarios is decreasing along with the increasing user speed, RAW group, and bandwidth. In the user speed scenario, the MCS 5 with RAW group = 2 and bandwidth = 2 MHz in v = 10 km/h scenario has the worst performance with an average delay which is about 0.065463 s, throughput is about 0.328120 Mbps, and PDR is about 99.8901%.

Performance Evaluation and Comparison of Scheduling Algorithms on 5G Networks using Network Simulator

In this research, we compared the Round Robin (RR) and the Proportional Fair (PF) algorithms for different user equipment density scenarios using voice and video traffic, to evaluate the key impact on performance of 5G mmwave network. This research simulated on NS3.27 with an integrated mmwave module. Based on the result, we found that the RR is a good choice for voice traffic. It has a throughput of 3.65% better than PF with similar fairness index. On the other hand, we found that the PF is the right choice for video traffic due to has better result for throughput. It has a throughput of 1.24% better than RR. For fairness index round robin has better result for voice and video traffic
