Abstract
The most promising technology for Internet of Things (IoT) is 3GPP LTE-advanced(LTE-A). For IoT Continuous low-rate streaming of data is reported from devices for a long period of time for IOT applications which imposes precise requirements on power saving. To manage power consumption, the discontinuous reception/transmission (DRX/DTX) mechanism is defined by 3GPP LTE-A which allow devices to switch off their radio interfaces and sleep in various patterns. Existing methods havecontributed much to evaluate the performance of DRX/DTX. This paper briefs about the DRX/DTX optimization, by asking how to maximize the sleep periods of devices while guarantee their quality-of-service (QoS), especially on the aspects of traffic bit-rate,packet loss rate and packet delay in IoT applications. Efficient schemes to optimize DRX/DTX parameters and schedule devices’ packets with the base station are proposed. To manage the impacts between QoS parameters and DRX/DTX configurations is the main idea. Simulation results shows that it guarantees throughput, packet loss rate,packet delay, and energy while save energy of user equipment. © Research India Publications.
