Problems solved by technology

[0006] (2) The election of the cluster head is generated with equal probability, without taking into account the difference in energy between different nodes
[0007] (3) The transmission distance of LEACH is relatively long, and the data fusion is relatively small, which requires the transmission of more data to a longer distance, thereby increasing energy consumption
Some cluster head nodes far away from the base station consume energy faster, which will affect the coverage and lifetime of the network

Abstract

The invention discloses an energy-consumption-based routing optimization algorithm for a wireless sensor network. The algorithm is characterized in that the number of optimized cluster head nodes is selected, and an optimal node is selected as a cluster head, so that the quality of the network is improved, the energy consumption of the network is lowered, and the life cycle of the network is prolonged; and the number of the cluster head nodes is selected according to energy consumed by the transmission of data, energy consumed by the reception of the data, energy consumed by the cluster head nodes and energy consumed by the transmission of an ADV message, the optimal node is selected as the cluster head according to the residual energy of the nodes, the average residual energy of the network, the energy consumption of the last round of the nodes and the average energy consumption of the last round of the network. The distribution of the cluster head nodes is balanced to a certain extent, the energy consumption of the nodes can be effectively lowered, the life cycle of the network can be prolonged, and the algorithm is widely applicable to the wireless sensor network.

Description

technical field [0001] The invention belongs to the technical field of wireless sensor networks, and relates to a routing optimization algorithm for wireless sensor networks based on energy consumption. Background technique [0002] Routing protocols for wireless sensor networks are divided into flat routing protocols and clustering routing protocols. The characteristics of the planar routing protocol are that the algorithm is simple, easy to implement, and the nodes are equal. In principle, there is no bottleneck, and the robustness is good. However, it generally needs to sacrifice storage space to maintain a large number of routing tables, and also requires control information to maintain routing. Moreover, the scalability is poor, which greatly increases the communication burden, causes information redundancy and congestion, causes large energy loss and long delay, and is not suitable for the application of large-scale sensor networks. The basic idea of ​​cluster routing...
