Abstract： As a classic low-power adaptive hierarchical routing protocol, LEACH protocol is widely used in application scenarios that require continuous monitoring. Although the LEACH protocol balances network energy consumption to a certain extent, it lacks the limitations of node energy and location information and other parameters, and there are problems such as uneven energy consumption and premature death of nodes. According to these problems, this paper proposes the LEACH-PC protocol, which considers the size of the cluster on the basis of dividing the network into regions, and at the same time adjusts various gain parameters of the cluster head election threshold function, thereby prolonging the network life of WSN. The simulation experiment shows that the LEACH-PC protocol reduces network energy consumption and has delayed network death time relative to the LEACH protocol.
Key words : wireless sensor network; LEACH protocol; life cycle; cluster head election
