Abstract corregit This is a research project in the field of Smart Homes with the aim to develop a Smart Home Environment using Multi-Agent system negotiation and Rule-Based protocols. Thesimulation will be developed using the program Netbeans (Java) and Prolog. It will permit to control the status of the devices via Intelligent Plugs and display alerts. An Intelligent Plug is an appliance that goes between the plug and the socket, and the user can switch on and off using Wi-Fi connection. The objective is to reduce the power consumption of household appliances using intelligent-adaptive algorithms, to develop a user-friendly interface and also to gain a better command over them. The developed application will permit the interaction of the user with it, enhancing the user’s comfort at its finest. Once the expert system has been implemented, a Multi-Agent environment will be developed involving five different houses. It will have two different negotiation protocols: one to control the heat of the five houses and the other to control the total energy consumption of the neighbourhood.
