A clustering WSN routing protocol based on node energy and multipath

Wireless Sensor Network (WSN) is a self-organizing adaptive network composed of infinite sensor nodes which can collect the data information, process the data information and transmit mutual data information. However, its node power is very limited. The main responsibility of its routing protocol is to find the scientific and correct forwarding path for the data transmission using the least amount of energy. The routing protocol of WSN focuses on energy-first, data-centric and application-dependent. In this paper, we mainly study cluster routing protocol in the wireless sensor network, and analyze the advantages and disadvantages of LEACH protocol, pointed out the problem. We aiming at the problems existing in the original LEACH protocol, the cluster head election, the special node processing and inter cluster routing problem were improved respectively, and then an improved protocol called LEACH-Impt was proposed. With MATLAB simulation, we compare its performance with the LEACH in the number of survival points and the transmission efficiency of the data. In the last, we compare the existing time and work efficiency between the old and new LEACH protocol in the hardware system.
