MWN is an autonomous system of mobile and/or immobile nodes, which are connected by wireless links. In MWN, any two nodes can communicate directly if their packets can be correctly decoded under the desired signal-to-interference-plus-noise-ratio is achieved. Otherwise, the packets are relayed from the originating node to the final destination node via the intermediate nodes by multihop fashion. This MWN is also known as peer-to-peer networks without the aid of any centralized administration.

WSAN is a distributed system of sensors and actuators. Sensors gather information about the physical world and actuators perform actions to change the behavior of the physical world. For real deployment, stand-alone WSAN is insufficient. A gateway device is essential to enable end-to-end connectivity between the sensors and/or actuators of WSAN and the Internet devices.

CPS is defined as a system involving the close integration of the cyber world and physical environments. CPS will contribute to safety, efficiency, comfort and human health, and help solving key challenges of our society, such as the ageing population, limited resources, mobility, or the shift towards renewable energies. One example of CPS applications is an intelligent home automation for comfort control. In home networks, appliances, devices, and sensors are expected to help people live on their own comfortable. The sensors pass information among themselves and to a sink. The gathered data is analyzed to infer activities of daily living, which can give important clues to a person's state of comfortable, relax, restful, and pleasant.

WNC refers to a technique where a wireless device is allowed to generate output data by mixing its received data. The unique characteristics of wireless medium renders WNC particularly advantageous, e.g., this technique can be used to achieve the minimum energy-per-bit for multicasting in a multihop wireless network. Recently this technique has been developed into a link layer enhancement scheme. The WNC engine in the link layer can opportunistically mix the outgoing packets to reduce the transmissions in the air.

HEMS is a system that includes all the necessary elements to achieve the reduction of electricity consumption in home environments. One of its main elements is a smart energy home gateway, which is able to communicate and manage the rest of the home appliances and offers an alternative to reduce the entire electricity consumption. The goal of the smart energy home gateway is to optimize energy control by managing all home appliances, devices, sensors, and actuators.
