A distributed strategy for the multi-target rescue using a UAV swarm under communication constraints
Published 2022-09-01“…The current designs of the cooperative decision-making of an unmanned aerial vehicle (UAV) swarm usually adopt unreasonable assumptions on the communication ability between UAVs.Focusing on a multi-target rescue problem of a UAV swarm under constraints of energy, load and path, the limitation on the information sharing due to the communication constraints and the flight path of UAVs were taken into account.Firstly, the problem was formulated as a partially observable Markov decision process (POMDP).Then, a recurrent neural network was used to propose a deep-reinforcement-learning-based distributed rescue strategy, which is able to adapt to the changeable communication topology.Simulation results show that the proposed strategy outperforms other strategies under communication constraints, and further show that a careful joint setting of the size and communication ability of a UAV swarm is needed to achieve the best compromise between the UAV swarm rescue performance and the cost.…”

An energy balance AODV protocol with multicast route discovery for wireless body area networks
Published 2016-08-01“…In AODV protocol with the dynamic topology networks,the source node S requests a route to an arbitrary destination node D with flooding broadcast the RREQ message,but there is only one destination node sink in a WBAN,other nodes involved in receiving and forwarding RREQ have wasted energy except the nodes on minimum hop count routing.An energy balance AODV protocol with multicast route discovery for wireless body area networks was proposed,it increased the minimum hop count to sink hops,the next hop node to sink next and the node itself has the forwarding capability isforward three parameters in a hello message,and selects neighbors which could reach the sink only to participate in forwarding the RREQ message.This protocol effectively reduces the energy cost of the routing discovery through changing the broadcast to multicast,and prolongs the service life of WBAN with energy balance.The performance analysis and simulation experiment indicate that the proposed protocol is more advantaged than similar EAAODV in the number of RREQ,packet delivery ratio and energy consumption.…”

Research on low-energy-consumption deployment of emergency UAV network for integrated communication-navigating-sensing
Published 2022-07-01“…In public emergencies such as accident relief, rescue workers are faced with challenges, such as poor communication, unstable navigating, and inaccurate disaster sensing.It is necessary to deploy an emergency unmanned aerial vehicle (UAV) network to guarantee the services of communication-navigating-sensing.Aiming at alleviating the problem of limited energy of UAV, a low-energy-consumption deployment of an emergency UAV network was first proposed for integrated communication-navigating-sensing (ICNS).The proposed scheme was able to realize network topology reconstruction and role cognition on demand.Then, a particle swarm algorithm based hierarchical matching decision-making algorithm was presented to jointly optimize three sub-problems, including the associations between UAVs and users, the resource allocation for multi-role UAV communications, and the UAV position.Simulation results show that the proposed ICNS scheme can achieve flexible adaptation of the multi-objective requirements and limited network resources, and dramatically reduce the demand for the number of UAVs and the deployment energy consumption.…”

Design of nodes importance assessment method for complex network based on neighborhood information
Published 2024-03-01“…Accurate identification of influential nodes in complex networks is crucial for network management and network security.The local centrality method is concise and easy to use, but ignores the topological relationship between neighboring nodes and cannot provide globally optimal results.A node importance assessment method was proposed to correlate the node edge relationship and topology, which firstly applied the H-index and information entropy to assess the nodes, then combined the structural holes of the nodes with the structural characteristics of the nodes, and took into account the attribute of “bridging” while focusing on the node’s own quality and the amount of information about the neighboring nodes.The algorithm was validated by simulating the propagation process using the SIR model, and the Kendall correlation coefficient, complementary cumulative distribution function and propagation influence were applied to validate the validity and applicability of the method.Comparison of the experimental results on six real network datasets shows that the proposed method is more accurate than the traditional centrality methods in identifying and ordering the key nodes in the network.…”
