LEACH Clustering Routing Protocol for WSN Dongfeng Guo and Lijun Xu
Abstract The node energy, storage space, and computation ability are limited, so energy saving is the primary goal in the design of wireless routing. The traditional wireless routing cannot be directly applied to the WSN, so WSN routing protocol research has important practical significance. The improved LEACH protocol means to make each nodes energy utilization more equalized to extend the total amount of data and network survival time. To improve the performance of the whole network is a crucial principle for the research of WSN according to a specific application in the future. Keywords WSN

20.1 Introduction Wireless sensor network consists of a large number of nodes, which exchange data through wireless communication technology. Wireless sensor network collects information from plenty of nodes in sensors and has a data processing and integration to convey the final information to the observer. Routing protocol is so critical for network that it has a direct impact on network performance, efficiency, and safety [1]. Wireless sensor network has its own characteristics and is different from the traditional network, and its routing protocol presents difference from the letter. The routing protocol of traditional network cannot be directly applied to

wireless sensor network [2]. As long as the differences between wireless sensor network and IP routing protocols as following: when designing routing protocols, node energy of wireless sensor network is limited and on the important position. In the transmission process, node energy is far away from the network center, while many-routing protocols mainly face much to one of the data current and one to much of the control current rather than point to point communication in the traditional network. During the data transmission, first, it is to do an integration of data processing. Mobility of wireless sensor network is poorer than the Ad Hoc networks [3].
20.2 A Wireless Sensor 20.2.1 Architecture of Wireless Sensor Network Wireless sensor network is generally composed of the sensor nodes, cluster nodes, and management nodes, and sometimes it contains Internet, satellite links, and console. Aggregation has a received data processing and integration to convey the handled information to the management node through the Internet or satellite links. Furthermore, aggregation node has the function of data processing and transmission and designs enhanced sensor nodes in order to have much capacity and processing space [4]. While management nodes examine and manage the whole network, receive
