Cognitive radio auto-adaptive sensing algorithm based on POMDP
Published 2013-06-01“…In order to design an appropriate spectrum sensing mechanism in millisecond spectrum hole environment,the optimal data transmission time of secondary users was derived to maximize the data throughput.Furthermore,in order to exploit the millisecond spectrum holes,an auto-adaptive spectrum sensing algorithm based on POMDP (partially observ-able Markov decision process) was proposed.This algorithm executes spectrum sensing or data transmission action in the current decision epoch based on the belief vector and the observation result in the last decision epoch.Simulation results show that the proposed algorithm can constrain the collision probability between primary users and secondary users,and improve systemic spectrum utilization at the same time.…”

Computation offloading and resource allocation strategy based on deep reinforcement learning
Published 2023-07-01“…In order to expand the coverage and computing power of vehicle edge network, a computation offloading architecture was proposed for space-air-ground integrated vehicle network (SAGVN).With the consideration of the delay and energy consumption constraints of computing tasks, as well as the spectrum, computing and storage constraints in the SAGVN, the joint optimization problem of computation offloading decision and resource allocation was modeled as a mixed integer nonlinear programming problem.Based on the reinforcement learning method, the original problem was transformed into a Markov process, and a deep reinforcement learning algorithm was proposed to solve the problem.The proposed algorithm has the good convergence.The simulation results show that the proposed algorithm outperforms other algorithms in terms of task delay and success rate.…”

Community Structure Perception Routing Mecbanism in Intermittently Connected Wireless Network
Published 2015-04-01“…Based on the differences of social relations between nodes,a community structure perception routing mechanism was proposed for the reason of low message delivery probability in intermittently connected wireless network.According to state information of nodes in each movement cycle,Markov models was established to show the state transition process among nodes,further,the centrality of node was obtained.Then considering about the centrality of node and exploiting the method of community label switching,network structure was checked dynamically.Finally,the central node in the community was chosen as the relay node to forward messages.Results show that the proposed method is accurate,and the performance of delivery ratio can be improved 90% approximately,optimizing the network performance greatly.…”
