Abstract:

An algorithm for routing optimization of an energy and path constrained wireless sensor network is proposed to solve the energy limitation problem which is caused by the frequent use of a single path by traditional wireless sensor network routing algorithms. By considering the load balancing and energy efficiency of wireless sensor networks, the concept of flight feasible domain is introduced to achieve efficient data transmission. Furthermore, energy and distance factors are added to ensure uniform and reasonable energy distribution among network nodes, so that the low-power and energy-efficient functional requirements of the wireless sensor network are satisfied. . Experimental results show that the proposed method can improve the network load balancing effectively, avoid the network segmentation caused by premature exhaustion of some nodes, and prolong the lifetime of the network.
