Due to impact of surrounding environment on wireless sensor networks（ WSNs）

it will produce signal attenuation and loss in layout to special environment

resulting in poor communication.Aimed at the problem

propose a new routing algorithm based on LEACH routing protocol which adapts to special environment（ long straight space）.This algorithm uses chain transmission

it transmits the signal from the inside one by one to the cluster head that is in the outer side of the space and closer to the base station location

and overcomes problem of internal nodes dying too fast.Meanwhile

use chain transmission and improves the cluster head threshold and cluster radius in cluster

reduce energy consumption

improve stability

and overcome deficiencies of the LEACH algorithm.
