Today, wireless sensor networks have been used in many applications according to their benefits such as simple and inexpensive implementation, low power consumption and high scalability. Designing sustainable wireless sensor networks is a very challenging issue. It is expected that sensors with limit energy to work automatically for a long time. However, replacement of broken batteries may be impossible with high costs or even in hard environments. On the other hand, unlike other networks, wireless sensor networks are designed for specific small-scale applications such as medical monitoring systems and large scale such as environmental monitoring. In this context, many researches have been conducted to propose a wide range of solutions for the problem of energy saving. In this paper, a routing algorithm has been designed to generate the best route between sensor nodes and local aggregate nodes for achieving proper traffic distribution and thus balancing the energy consumption of the middle nodes. Creating such a balance will help to increase the lifetime of the network and it will improve the energy consumption pattern in wireless sensor networks with limited power sources. On the other hand, it is attempted to increase the possibility of load distribution at low-density points using the possibility of changing the range of nodes.
