A Zone-Based Self-Organized Handover Scheme for Heterogeneous Mobile and Ad Hoc Networks by Murad Khan, Kijun Han

An incentive mechanism with bandwidth allocation for federated learning by Yingyun GUO, Bo GAO, Zhifei ZHANG, Yu ZHANG, Ke XIONG

“…Federated learning (FL) is an emerging machine learning paradigm that can make full use of crowd sourced mobile resources for training on decentralized data.However, it is challenging to deploy FL over a wireless network because of the limited bandwidth and clients’ selfishness.To address these challenges, an incentive mechanism with bandwidth allocation (IMBA) was proposed.Considering the difference between clients' data quality and computing power, IMBA designs a payment scheme to incentivize high-quality clients to contribute their computing resources, thus improving the training accuracy of the model.By minimizing the weight sum of training time and payment cost, the optimal payment and bandwidth allocation scheme was determined, and the training delay was reduced by optimizing bandwidth allocation.Experiments show that IMBA effectively improves training accuracy, reduces the training delay and helps the server flexibly balance training delay and hiring payment.…”

Power control strategy with joint of multi-packet reception and fuzzy logic control by Jiang-hong HAN, Song-hua HU, Bin LIU, Zhen CHEN, Lei LIU

“…In order to meet the needs of energy saving in wireless networks,a power control strategy with joint of multi-packet reception and fuzzy logic was proposed.Firstly,based on the power control with successive interference cancellation (SIC),transmission power was divided into several decodable power levels.Secondly,fuzzy logic control algorithm was adopted to select the optimal transmission power for SIC.In addition,three parameters were designed as fuzzy logic control inputs for power selection,which were the distance between transmitters and receivers,the number of neighboring nodes and the residual energy of transmitters.Simulation results show that power control strategy with joint of multi-packet reception and fuzzy logic control not only betters average network throughput than other power control strategy for SIC,but also saves more energy so that the network lifecycle would be significantly extended.…”

Asynchronous perception algorithm based on energy detection by Pan YU, Bin LI, Cheng-lin ZHAO

“…In the future heterogeneous wireless networks,since primary user (PU) and cognitive secondary user (SU) are not coordinated to be synchronous,it will result in sense timing difference between PU’s transmitter and SU’s receiver.For this asynchronous sense case,a new asynchronous sensing algorithm based on Bayesian estimation theory was proposed.A unified dynamic state space model was first proposed to describe the observable energy relationship with dynamic PU state and unknown timing difference.Then,an iterative estimation scheme was designed using stochastic finite set and the rules of maximum posterior probability.Finally,approximated estimation results were obtained by using a particle filter.The simulation results show that the proposed asynchronous scheme significantly eliminates the uncertainty of the received signal information and thus improves the spectrum sensing performance by obtaining the time difference accurately.…”
