Fault tolerance improvement un wireless sensor networks using of distributed energy-based routing algorithm

In recent years, advances in the electronics and communications industry have enabled the production of low-cost, low-cost, low-power, multi-purpose sensor nodes that enable short-distance communication. The advancement of technology in the field of wireless communications as well as the tendency to use low-cost, high-consumption products have led to the emergence of one of the most widely used networks called wireless sensor networks. Since most applications in wireless sensor networks are related to critical incident reporting, the need for reliable communication and access and protection seems critical. If a system fails periodically, it may have good availability because it may be too short. The main objective of this study is to present a comprehensive, optimal and efficient routing strategy to increase the network resistance to critical errors as well as to extend the network lifetime in order to optimally transmit sensor-measured information to the data collection and control center. Under normal network conditions. In sensor networks, the problem of fault detection and separation is a hardware task due to the nature of their structure and deployment. Types of bit errors in wireless communications can be classified as random or sequential errors. Bit .error can appear in any part of a data transfer sequence or radio packet
