Research of routing algorithm based on smart city and the design of multi-network integration

In the face of problems of communication network in the smart city, which is featured with the limited bandwidth and huge amount of data, it is difficult to ensure the validity of the data transmission. Based on the rate of timeliness and data transfer rate, this paper improves the LEACH algorithm, and shows that it can ensure the timeliness of various types of data transmission and improve the efficiency of data transmission by the simulation. In addition, this paper proposes an overall design of “one map-two line-four meter-four” network, which has been applied to the construction of Shenyang city. The demonstration project can meet the requirements of the smart city effectively and support the construction of the smart city strongly.
