    QoS-based sensing scheduling protocol for wireless sensor networks by YAO Dao-yuan1, WANG Hai-lin 1, ZHANG Bao-xian2, LIU Hai-tao1

    Published 2010-01-01
    “…To satisfy the requirements of event detected latency according to different applications with unbalanced node density in randomly deployed large-scale wireless sensor networks,an adaptive distributed sensing scheduling protocol(ADSSP) which adaptively adjusts the duty cycles of sensor nodes based on node density and balances the energy consumption among sensor nodes was proposed.Compared with the random scheduling protocol,ADSSP can provide guaranteed lower average detection latency and also prolong the network lifetime up to 30 percent under the same situation.…”

    Charging path optimization in mobile wireless rechargeable sensor networks by Quanlong NIU, Riheng JIA, Minglu LI

    Published 2023-12-01
    “…The wireless power transfer technique is promising in solving the energy bottleneck of sensor nodes in wireless sensor networks, which can thus prolong the network lifetime or even maintain sustainable network operations.Most existing works focused on optimizing the static chargers’ deployment or mobile chargers’ charging path for static sensor nodes with fixed sensor node positions, ignoring the scenario with mobile sensor nodes.Thus, design and optimize the charging path of a mobile charger was studied for dynamic wireless sensor networks with mobile sensor nodes, to maximize the charging utility within a finite time horizon, that is, the charger can encounter as more sensor nodes as possible in a limited time and charge them.Notice that the mobile charger may stop to simultaneously charge multiple nodes within its charging range during its charging tour.The proposed charging path optimization problem was proven to be an APX-hard problem.Then, based on the constructed directed acyclic graph using discretization method, a layer-wise pruning algorithm based on the backtracking method was proposed.The proposed algorithm took the solution generated by the greedy algorithm as the benchmark and searched the optimal charging path under a fixed time division by layer-wise pruning.Simulation results show that the proposed algorithm can effectively improve the charging utility .…”
