Grouping-Based Extended Discontinuous Reception with Adjustable eDRX Cycles for Smart Grid
Abstract
This paper investigates a grouping-based extended discontinuous reception (eDRX) scheme for smart grid in order to save energy efficiently. By dividing users into different groups and assigning them different eDRX parameters, each group can employ appropriate cycle of themselves and only respond in this cycle rather than work in the whole time. Based on a semi- Markov model, the proposed eDRX process has been simulated and compared with standard DRX from the aspects of power saving factor and wake-up delay. Simulation results show that our scheme outperforms standard DRX in many cases, and a good tradeoff between power saving factor and wake-up delay should be considered properly for practical applications.
