Research Cluster Headelection Mechanism Rrouting Protocol For Wireless Sensor Networks

In recent years, with the rapid development of science and technology level,wireless sensor network technology has made considerable progress, has become animportant technique is widely used, and experts at home and abroad scholars havebegun to widespread attention in wireless sensor network technology. Wireless sensornetworks (Wireless Senor Network, i.e. WSN) have energy storage capacity, limits theexpansion and fault tolerance, but the energy problem has been one of the most talkedabout research directions.Effectively improve network energy efficiency, will greatlyimprove the survival time of the network, thereby improving network performance.In this context, and dofor “the city’s public safety and security-based wirelesssensor network fault detection and fault-tolerant systems " project provides routingalgorithms, and provides a method to optimize the energy efficiency of the entiresystem. Therefore, this paper respectively in the third and fourth chapters proposed twoimproved algorithms.This paper presents the third chapter algorithm based voting mechanism and timing-driven mechanism-TDWV algorithm. Applied to the project for “the city’s publicsafety and security type wireless sensor network fault detection and fault-tolerantsystems ", mainly for temperature sensing, traffic monitoring and water qualitymonitoring sites need to be applied at all times real-time data.Voting process in thenode, TDWV algorithm considering the residual energy of the nodes, the nodescommunicate with each other and the energy consumption of the node incommunication with three base stations. Three values obtained by weighting the finalvalue is the node number of votes cast. After the polls close, and then the algorithmbased on the timing-driven mechanism, the node generates a timed length according tothe number of votes to participate in the cluster head election, which greatly optimizesthe process of saving energy allocation algorithm. Compared with LEACH protocol,TDWV algorithm in the network overall energy consumption, survival time, there hasbeen improved.In the fourth chapter，this paper focuses on a cluster-based energy-efficient routingprotocol——TEEN protocol modified protocol. Applied to the project for “the city’spublic safety and security type wireless sensor network fault detection and fault-tolerantsystems ", the main application areas for monitoring accidents, fires and traffic accidents and other emergencies.TEEN protocol for the uneven distribution of clusterhead, cluster head overburdened, leading to some hard threshold has not been activatedfrom the start node wasteful and its only suitable for small-scale networks such as lackof comprehensive partition, set the hard threshold to0and the use of multi-hopmechanisms and other measures, we propose a new TEEN—Falgorithm. Overallenergy consumption in the network, the survival time aspect, TEEN-F algorithm ’sperformance to be better than TEEN agreement.In this paper, the following work has been done: First introduce the concept,background, structure and applications of wireless sensor networks and the status ofdomestic and international research, analyzes need to be addressed. Second, re-introduces the wireless sensor network routing protocols, and analyzes and comparesthe existing routing protocol, highlighting the classic LEACH protocol and TEENprotocol to study proposed and the corresponding lack of improved methods TEENagreements exist. In the third chapter presents deficiencies of the existing routingprotocols, based on LEACH protocol is proposed based on the voting mechanism andtiming-driven mechanism algorithm-TDWV algorithm, the algorithm introduces thebackground, analysis and process, and then use the MATLAB TDWV simulationplatform for simulation algorithms and protocols LAACH comparison. In the fourthchapter presents proposed agreement and the corresponding lack of improved methodsTEEN algorithms exist. Then introduce the proposed entire operation process TEEN-Falgorithm. Then use the MATLAB simulation platform TEEN TEEN-F algorithm andprotocol simulation comparison. The simulation results show that the new algorithmproposed TDWV and TEEN-F protocol on energy consumption and network lifetimethan the original agreement has improved greatly, to achieve the desired requirements.Finally, the work done in this paper is summarized and the future research in the future.
