Multi-objective Optimization with QoS Constraints in WSNs
Keywords:sensor nodes, wireless sensor networks, QoS constraints, throughput, multi-objective combinatorial optimization
One of the most active research areas in wireless sensor networks are coverage and improving QoS parameters. This paper focuses on the deployment optimization problem of WSNs dedicated to the monitoring area of interest. In this kind of networks, nodes are classified into two classes: Sensor Nodes (SNs) deployed within the area of interest for targets coverage and Relay Nodes (RNs) which relay sensed messages generated by the sensor nodes up to the sink node. In this study, we propose a Multi-Objective Throughput and Lifetime Optimization (MOThLO) which maximizes simultaneously the throughput and lifetime of sensor nodes, while ensuring network energy, latency and sensors lifetime. In order to evaluate the performance of our proposal, we have conducted many tests.
