Aiming at problems of nodes are early dead and energy consumption of the entire network is not balanced in the limited node position

energy

frequency of WSNs for solid-state fermentation temperature measurement

can’t be solved effectively by conventional clustering routing algorithm

propose an uneven cluster routing protocol based on particle swarm optimization（PSO） algorithm.Firstly

according to network size

select fixed number of cluster head nodes

then the PSO and uneven cluster scheme are introduced to select the optimal cluster heads by evaluating factors which are the average Euclidean distance between nodes and their associated cluster heads and the size of cluster head coverage.Simulation experimental results demonstrate that the algorithm can efficiently improve the"hot zone"effect of network

balance energy consumption of nodes

and prolong network lifecycle.
