Research On Wireless Sensor Networks Of Non-uniform Clustering Routine Protocol

Over the last decade, with the sensor technology, network technology, microelectronics, communication technology and distributed information processing technology, fast development of wireless sensor network technology is becoming mature. Wireless sensor network nodes can collaborate on real-time monitoring, such as tasks, and the collected mass data processing, and then sent through a wireless network in a timely manner to the user. Wireless sensor networks deployed a large number of sensor nodes within a specific region. As the sensor node energy is limited, how to save the energy consumption of each node to balance the load on the entire wireless sensor networks, wireless sensor networks has become the most important problems.In wireless sensor networks, in order to reduce energy consumption, to provide network scalability, and flexible, and reliable communication, wireless sensor networks generally use the classification system. Network is divided into clusters, cluster members from the cluster head nodes and nodes, cluster head nodes multi-hop transmission of data. Cluster head node can require the formation of higher-level network, until the last and highest level of Sink nodes combine to form a network. Wireless sensor network node in the cluster head management of all the members of the cluster node, the node of the members of the integration of data collected, forwarded to coordinate the work of the entire cluster. Members of the node is responsible for sensing and gathering information, sending data to the cluster head node.This paper studies the wireless sensor network clustering system, analysis of several typical clustering algorithm based on the traditional clustering algorithm was improved. As in the traditional clustering algorithm, the sensor network application of the various clusters of the same clustering protocols, makes the whole wireless sensor network nodes in each cluster in the same number. Results Although the balance of the members of the energy consumption between nodes, but did not take into account the energy consumption among cluster head balance. Therefore, by studying the cluster head of cluster agreement to change the allocation of fixed nodes in the cluster, according to Sink node cluster head and cluster nodes from the adjustment of the number of requests for wireless sensor networks, designed a way to reduce energy consumption, extend the network lifetime of non-uniform clustering routing protocols.This paper, two algorithms to simulate and analyze results CEUC (a novel cell energy balanced uneven clustering hierarchy scheme) algorithm, compared with Leach algorithm, CEUC algorithm can extend the death of the first node appearance time, which effectively extends the network lifetime.
