Connection and resource allocation of IoT sensors to cellular technology-LTE

The number of sensor nodes being used for the applications is increasing dramatically every year. In this paper we consider LTE for sensor networks. There is little published research on resource allocation of sensor networks in LTE. Theoretical calculation carried out for mobile users in LTE was used and recreated for sensor nodes transmitting. Existing literature has carried this out for mobile users on LTE network, transmitting 10 Kb, theoretically without mentioning the total resource blocks allocated for the network based on the bandwidth. In this paper we utilise LTE for sensor networks and investigate how many sensor nodes can transmit and how many bytes will be transmitted per Resource Block (RB). Theoretical calculation was carried out for sensor nodes to find out the data that can be transmitted per RB by sensor nodes transmitting 10 Kb. We find significantly different results when carrying out simulation for a critical sensor network, using realistic real world parameters for the LTE network. We clearly specify the bandwidth and resource blocks used for the simulation in this paper. We carry out simulation in OMNET to create sensor network scenario demonstrating results with 29 sensor nodes transmitting 1 Kb of data.
