Performance analysis and optimization for coverage classes updating mechanism of narrow-band internet of things
Published 2018-11-01“…A Markov chain model with coverage classes as state variables was established to describe the dynamics of the coverage classes updating mechanism of narrow-band internet of things (NB-IoT).An optimization model to minimize average probability of access failure as well as average power consumption was formulated,with which the effects of preamble repetition number,system load and global maximum transmission number on the optimal configuration of maximum transmission number of each coverage class was analyzed.Numerical analysis results show that the maximum transmission number of normal coverage and extended coverage have a great influence on the system performance and their value ranges should be set within[1,5]and[1,7]respectively.However,the maximum transmission number of extreme coverage has little influence on the system performance,its value could be any one in[1,10]but the recommended value is 1.In addition,the average power consumption of the model that introduced coverage classes’ rollback mechanism is about 95% lower than the model proposed by 3GPP.…”

Joint trade-off optimization algorithm based on cooperative spectrum sensing throughput
Published 2011-11-01“…The achievable data throughput of the cognitive network was modeled to optimize the overhead and performance of the cooperative system thoroughly.Considering the soft data combination decision,the joint trade-off optimization of the local sampling number and cooperative user number was modeled based on the achievable data throughput.The global optimal solution was achieved with inexact line search algorithm,which is based on Armijo rule and lopsided search step technique.Consequently,the validity of the optimization model was verified both by the numerical computation and by Monte-Carlo simulation tests.The joint trade-off optimization of the sampling number and cooperative user number was achieved in cooperative sensing based on the throughput maximizing criterion.…”
