Abstract— Electricity usage is increasing day by day due to the
changing life style of home user and an increase in appliances in
the home area network. Our proposed home energy management
system for home users will monitor, manage and control the
usage of home appliances, by reducing the monthly electricity bill
The proposed wireless architecture consists of an appliance
control device called Wireless Enabled Electricity Manager
(WEEMAN) installed next to a switch board or every device/
appliance in a room. The central node called smart meter runs an
algorithm called Availability Based Energy Management
algorithm. This algorithm learns about the previous usage
patterns of the appliances, collects real time power consumption
of appliances from WEEMAN to generate efficient energy load
patterns. The highpoint of the algorithm is that it gives an option
for the user to set their monthly current bill and pro-actively
control the operation of all the appliances according to the
amount. We have developed a hardware test bed consisting of
WEEMAN connected to some selected appliances and a smart
meter to control every WEEMAN
