Load Balanced Routing with Constant Stretch for Wireless Sensor Network with Holes

Due to its simplicity and scalability, geographical routing is a common method in wireless sensor networks that allows routing paths close to optimal in the network without vulnerability. However, with the advent of halls, geographical routing faces the problem of hole spreading and routing path expansion. In some recent proposals, we are trying to solve these problems by placing a special forbidden band around the hole, which helps to improve traffic congestion at the hole boundary. The load is not distributed.

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

Wireless sensor network is a special ad hoc network consisting of a number of low cost, low power, multifunction wireless sensor nodes with sensing, wireless communication and computational functions. These sensor nodes communicate over short distances via wireless media and cooperate in common tasks such as environmental monitoring, military monitoring, and industrial process control. The wireless sensor network opens up new opportunities to observe the physical environment around us and interact with it. By doing so, you can collect and collect data that was previously difficult or impossible. Wireless sensor networks provide a new way to provide information from a variety of applications, but extracting data from the sensor network is considered a difficult task, regardless of the nature of the physical environment. Data distribution and collection are two terms used in sensor networks to represent two types of data processing methods.

A wireless sensor network is a wireless network of spatially distributed autonomous devices that uses sensors to measure physical or environmental quantities such as temperature, sound, vibration, pressure, and movement in various locations. The main purpose of a wireless sensor network is to collect information from the target domain and pass it to a specific task. Such a network usually consists of a number of wireless sensor nodes arranged in a simple way, each node being connected to a network of energy sources, which consists of one or more sensors, a low power transceiver, a processor, and possibly a battery Become. Since the sensor node's radio consumes a lot of energy, the lifetime of the network is shortened. In order to reduce the energy consumption of these sensor nodes, the design of low power electronic devices has been studied. Due to hardware limitations, further energy efficiency can be achieved by designing an energy efficient communication protocol.
