Aiming at high network energy consumption and data delay induced by mobile sink in wireless sensor networks (WSNs), this paper proposes a cluster-based optimization algorithm called Cluster-Based Energy Optimization with Mobile Sink (CEOMS). CEOMS constructs the density function of nodes firstly then assigns higher remaining as cluster heads according to function. Meanwhile, directivity motion performance is constructed enhance probability remote being assigned heads. Secondly, based on Low...
In wireless sensor networks (WSNs), finding the best transmission route from each node to mobile sink is not a simple task because of dynamic characteristics and cluster transmission. order balance energy consumption reduce collisions in transmissions, this paper proposes Dynamic Spanning Tree with Mobile Sink (DSTMS) routing algorithm. Firstly, based on Low Energy Adaptive Clustering Hierarchy Protocol (LEACH), multi-layer framework minimum spanning tree (MST) constructed optimize data...
In wireless sensor networks (WSNs), due to the limited energy of nodes, how design efficient hierarchical routing algorithms balance network resources and extend life is an important problem be solved. Aiming at problems such as random selection cluster head, redundancy working node, construction head transmission path, which affect consumption, this paper proposes a multihop algorithm based on path tree (MHRA‐PT) optimize energy. Firstly, some nodes are those close base station have large...
When some nodes cooperatively track moving targets in a wireless sensor network, things including network working node selection and energy consumption are influenced. Thus, this paper proposes an improved algorithm LEACH-MTC (LEACH with Moving Target Constraint) based on low adaptive clustering hierarchy protocol (LEACH). First, the two-step linearization of nonlinear dynamic model, state target is predicted by extended Kalman filter (EKF). Second, combining prediction performance...
In multisensor cooperative detection network, some random disturbances, energy carried by sensor, distance between target and sensor node, so on all affect the selection scheme. To effectively select sensors for detecting target, a novel method considering uncertainty disturbance is proposed under constraints of estimation accuracy consumption. Firstly, problem modeled as binary form optimization with penalty term to minimize number sensors. Secondly, factors (precision, energy, distance,...
