Aiming at complexity of wireless sensor networks（ WSNs） deployment environment

which leads to high packet loss rate and premature death of some nodes

a transmission-reliable energy consumption balanced routing protocol is proposed. The protocol first establishes a routing table for each node through signal broadcast between nodes

and then the node selects the most suitable next hop forwarding node from the routing table according to the transmission cost function. Because of overall consideration of the factors such as residual energy consumption of node

signal strength

hop count and link quality

the energy consumption of the nodes in the network is balanced with high-reliable signal transmission

so as to prolong the network lifetime. In the simulation experiment

survival time of network

mean value of residual energy of the network and energy variance of nodes are analyzed and the validity of this protocol is verified.
