Novel Modification of the Collective Dynamic Routing Method for Sensors’ Communication in Wi-Fi Public Networks

Abstract

The widespread use of the Internet of Things makes it relevant to use public IP networks for simultaneous access by both users and wireless sensors. To achieve this, a significant reduction in the subscriber devices’ energy consumption is required. This paper analyzes the application features of the collective dynamic routing method both with and without the use of a robust method for estimating the channel data rate for sensors’ communication in wireless public networks. Based on the analysis, a novel modification of the collective dynamic routing method has been developed that reduces the sensors’ energy consumption while keeping a high data rate and short delivery time for users. An analysis of the network load, the total data transfer rate over the network, and the parameters affecting the sensors’ energy consumption was carried out for a segment of a seamless IEEE 802.11ax network. The simulation demonstrated a high efficiency of using a novel modification of the collective dynamic routing method for access to users and wireless sensors.

“…To reduce the intra-system interference level, FTP procedures are used [ 16 , 17 , 18 ]. To reduce the intra-system interference flow, routing procedures are used [ 6 , 19 , 20 ].…”

“…The IOM of IP networks proposed in [ 7 ] and described in [ 8 , 9 , 10 , 21 ] involves optimizing parameters for each route from a multitude of valid routs set , including both one-dimensional and multidimensional routes, and informing network nodes about the optimal routes set according to which the data will be transmitted. However, valid route sets and optimal route sets are formed only in the classical CDR method, which, as shown in [ 6 ], is not applicable in heterogeneous Wi-Fi networks simultaneously serving mobile users and sensors. To apply the IOM in such networks, it is necessary to use a novel modification of the CDR method presented in [ 6 ].…”
