Abstract EN
In order to maximize network lifetime and balance energy consumption when sink nodes can move, maximizing lifetime of wireless sensor networks with mobile sink nodes (MLMS) is researched.
The movement path selection method of sink nodes is proposed.
Modified subtractive clustering method, k-means method, and nearest neighbor interpolation method are used to obtain the movement paths.
The lifetime optimization model is established under flow constraint, energy consumption constraint, link transmission constraint, and other constraints.
The model is solved from the perspective of static and mobile data gathering of sink nodes.
Subgradient method is used to solve the lifetime optimization model when one sink node stays at one anchor location.
Geometric method is used to evaluate the amount of gathering data when sink nodes are moving.
Finally, all sensor nodes transmit data according to the optimal data transmission scheme.
Sink nodes gather the data along the shortest movement paths.
Simulation results show that MLMS can prolong network lifetime, balance node energy consumption, and reduce data gathering latency under appropriate parameters.
Under certain conditions, it outperforms Ratio_w, TPGF, RCC, and GRND.
