Coverage scheduling algorithm of mobile sensor nodes for optimizing network lifetime
प्रकाशित 2018-05-01“…In order to solve the coverage blind problem caused by deployment and failure of heterogeneous static sensor nodes,a coverage scheduling algorithm of mobile sensor nodes for optimizing network lifetime (CSA) was proposed.CSA considerd heterogeneous perceived radius of static sensor nodes and calculates the location of mobile sensor nodes based on the information of neighbor static sensor nodes.According to the location reported by static sensor nodes,coverage scheduling model was established.Heuristic solution method was proposed,to solve the scheduling model,and optimal location of mobile sensor nodes was obtained.The simulation results show that CSA can improve regional coverage and the number of survival static sensor nodes,improve network lifetime and reduce energy consumption of average static sensor nodes.Under certain conditions,CSA is better than Mno,MNode and MGrid algorithms.…”

Node placement strategy in wireless sensor network
प्रकाशित 2013“…Node placement influences the target position, coverage area, and connectivity in sensor networks.In random deployment, sensor nodes are deployed randomly in a non-invasive way.The deployment process may cause issues like coverage holes, overlapping, and connectivity failure.Enhancing coverage and connectivity are important for sensor networks to provide a reliable communication within sensing.Placing many sensor nodes in a WSN application region area is not the best solution due to cost and it results in multiple sensors used.Mobile sensor node is used as an alternative to overcome the random deployment problem.The virtual force based self node deployment is used in the mobility sensor to improve the coverage and connectivity area.Virtual Force Algorithm (VFA) approach using virtual repulsive and attractive forces is used to find the optimal node placement to minimize the problems. …”

Charging path optimization in mobile wireless rechargeable sensor networks
प्रकाशित 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 .…”
