Figure 7. The outcomes of the Monitoring and Control of the Greenhouse soil and climate Conditions for tomato crops-Design and Development a Control and Monitoring System for Greenhouse Conditions Based-On Multi Agent System

In the past generation greenhouses it was enough to have one cabled measurement point in
the middle to provide the information to the greenhouse automation system. The system itself was
usually simple without opportunities to control locally heating, lights, ventilation or some other
activity, which was affecting the greenhouse interior climate. The optimal greenhouse climate and
soil adjustment can enable us to improve productivity and to achieve remarkable energy savings. In
this paper we proposed a multi-agent methodology for integrated management systems in
greenhouses. In this regards wireless sensor networks play a vital role to monitor greenhouse and
environment parameters. Each controlled process of the greenhouse environment is modeled as an
autonomous agent with its own inputs, its own outputs and its own interactions with the other
agents. Each agent acts autonomously, as it knows a priori the desired environmental set-points. In
this way, any possible conflicting decisions of conventional environmental control methodologies
are resolved through negotiations between the agents so that the possible optimal integrated solution
is achieved. The developed system is simple, cost effective, and easily installable.
