What is HAN?
HAN represents the Home Area Network. It is a network that is set up and managed inside a small border, frequently a house or small office/home office (SOHO). It allows the connection and sharing of resources such as the Internet among computers, mobile and some devices over a network connection.
The main hub of a HAN is the router. In some cases, the router is linked to a modem, which connects with an ISP. The modem supports an Internet connection to the router, which consecutively supports Internet access to all connected devices inside the home.
In larger homes, a HAN can involve repeaters to extend the area of the wireless signal. Both long distances and objects, particularly cement walls can generate Wi-Fi signals to reduce.
A weak wireless connection can be usable, but it can be inconsistent and make slow data transfer cost. Wi-Fi repeaters or "mesh networks" solve this issue by promoting the signal in several areas of the home.
Home networks can link devices using wired or wireless technologies. Wired technologies were the first to arrive. Basic wired technology for HAN contains coaxial cable, PLC (powerline connection), twisted pairs, or newer technologies including optical fiber as a method of communication.
Current wireless technologies that are being utilized in a HAN contain Wi-Fi, ZigBee, and Bluetooth. In general cases, wireless technologies are preferred because of the ease of installation, convenience, and adaptability. Wireless technologies have the benefit of supporting remote control and monitoring.
The smart network is a current enhancement of the existing traditional power network. It is a smart network of several systems and subsystems created to support a cost-effective and reliable supply of electric power. It allows a real-time two-way data exchange among a customer and utility company through the exploitation of information and communication technologies (ICT) for the existing power network.
The problems facing information security, such as confidentiality, integrity, and availability, access to the commercial computer networks also influence HANs.
HANs can be used for private, commercial, or official goals, security and privacy are of major interest. There can be virus attacks, credit card extortion, and identity fraud. An encryption algorithm can be used to protect data transmission among HAN and the utility organization.
Managing HAN can be uncertain for traditional, non-technical home users. The main problems contain a lack of networking skills, potential difficulty of network management, heterogeneity of network devices, and the highly powerful feature of user applications. It is very complex to support a HAN management interface that is tailored for non-experts.
