Research on Network Parameter Model of Node Low Energy Consumption Wireless Sensor Network for Greenhouse

Abstract

Based on the node low energy consumption wireless sensor network for greenhouse, which takes mobile gathering node as center to self-organize subnets, this article mainly studies the relationship among network parameters and strike a balance between energy saving and system stability to establish the model of network parameter. Examples are illustrated to show how to determine network parameters and why the model is effective.

Research on Network Parameter Model of Node Low Energy Consumption Wireless Sensor Network for Greenhouse

“…About those described in detail in article [1], we just make an overview in order to save page space.…”

“…As sub-node is energy limited, we can get the maximum communication distance of the sub-node to ensure the connectivity in its connection time from article [1] easily:…”

“…(2) From article [1], when the gathering node communicates with its sub-nodes in connection time, the required minimum communication distance is:…”

“…Stabilization of the WSN for greenhouse includes two aspects: (1) The wireless transmission is stable, namely the system has no packet loss or packet loss within the permissible range; (2) The measurement and control for the system is stable, that is, the sampling period is shorter than the maximum allowable delay bound.…”

“…At present, some progress [1][2][3] has been made in the energy saving and system stability of WSN for greenhouse at home and abroad. Based on a fixed sampling period, article [2] has found out the permissible maximum packet loss rate while the system is stable; article [3] has proposed an algorithm to solve network congestion and so on.…”
