Abstract


Sensor technology, micro-electromechanical systems, modern networking and wireless communications technology, to promote the modern sense of the wireless sensor networks and development. Wireless sensor network is composed of a large number of sensor nodes through wireless communication to form a multi-hop ad hoc network system, its purpose is collaboration and awareness, collection and processing of information in the network area and sent to the viewer. Wireless sensor networks have network fast, flexible, and many other advantages, has high research value and very broad application prospects, causing the academia and industry attention. Firstly, the concept of wireless sensor networks, architecture, features and key technologies made a brief presentation; then existing wireless sensor network routing protocol to do a comparative study, summed up the characteristics of the sensor network routing protocols, the design requirements and performance indicators. This paper studies the wireless sensor network clustering routing protocol design. On a targeted selection of typical clustering routing protocol - LEACH protocol as the research object, analyzes the LEACH protocol deficiencies and propose their own improvement ideas. Original LEACH protocol uses the cluster head node randomly selected mode, the improved LEACH protocol number of the node residual energy as the main basis to select the cluster head node, the simulation results show that the improved LEACH algorithm performance has improved. In the study, based on LEACH protocol, this paper proposes a novel clustering routing algorithms - adaptive multi-hop clustering routing algorithm (MHAC). The algorithm adaptive clustering techniques and ways of combining multi-hop communication node based on local information independently decided to become a member of the cluster head node or nodes in the cluster area covered by class size limits within a certain range, all organized into a cluster head node trees routing tree, multi-hop communication system to transfer data to the base station. Simulation results show that the algorithm can effectively extend the network lifetime, save network energy consumption, network load balancing. Finally, the article ZigBee-based routing protocols for clustering have been studied. In analyzing joint topology network structure and cluster tree network topology of these three is proposed based on the clustering routing protocol with the corresponding cluster tree network networking solutions.
