A Heuristic Routing Protocol for Wireless Sensor Networks in Home Automation

In this paper, we proposed a greedy algorithm heuristic routing (GAHR) protocol and A * algorithm for route lookup. They are evaluated by traditional routing protocols to overcome those disadvantages and make them more suitable for home automation. The Wireless Sensor Network (WSN) has some unique features described in this article: Easy to deploy and reduce installation costs Scalability easily integrates with mobile user devices Before designing routing protocols for WSNHA , It must satisfy the protocol. And let's discuss some of them in paper.

Wireless sensor networks are networks of devices called wireless sensor nodes that collaboratively exchange information via wireless links. The wireless sensor network contains three types of nodes as coordinators; it organizes the network and helps maintain the routing table. Router: The router communicates with the coordinator and other routers to reduce the function of the terminal device and to provide the terminal device with a path for transmitting the data to the base station or the coordinator. Terminal device: The terminal device guarantees an interface with the real world. It detects the parameters of the design, communicates with the coordinator via the necessary routing protocol, and forwards the signal to the base station. The communication protocol is more complicated and designed according to the appropriate standards. The characteristics of the wireless sensor network are as follows

ZigBee is simpler and less expensive than other wireless personal area networks; ZigBee has several advantages over other wireless protocols, such as low power operation, high security, robustness, and wireless control and sensor network High performance scalability for IoT applications ZigBee devices can transmit data over long distances via a mesh network and can pass data through intermediate neighbors to reach more distances. Zigbee IoT applications include wireless ZigBee smart energy, home automation, light switches and so on.
