Abstract: This paper deals with the design of home automation system through multi-hop wireless communication using ARM. The multi-hop communication means the nodes within the network can able to communicate with the help of two or more nodes, which are acting as the relay nodes, between the source and destination node. In the computer program the user can create actions what should happen with devices connected to the destination node in the network. The end devices such as monitoring equipment using sensor, industrial motor, power transmission equipment, network equipment for routing and data transmission, automotive robot can be connected to the destination node depend on real time application and automation. This real time control and monitoring is achieved using uC/OS-II based ARM system with minimum power consumption and highly enhanced secure avoidance of malicious attack.

Keywords: OLSR based multi-hop communication with enhanced secure avoidance of malicious attack.
