A Mobile Sink Data Collection Algorithm Based on JGLE Metrics
Yu Lao Han · 2021
Aiming at the problem of energy hole in data collection in wireless sensor network, the paper proposes a mobile Sink data collection algorithm called MSDCA-JGLE in which the JGLE metrics is applied to dynamically select cluster head. Aiming at the NP-hard problem of mobile path planning of the Sink in cluster head nodes, an improved nearest neighbor algorithm is presented to get the approximate optimal solution of the problem. The simulation results show that the proposed algorithm can balance the energy consumption of network nodes, maximize the network life, and ensure the reliability and integrity of data collection.
