Energy Efficient Optimization Multipath Routing Protocol Of Wireless Sensor Networks

Information is an information-based premise, without it, information transmission, processing and applications will not have any significance, there would be no informationization. While information acquisition is the basic function of wireless sensor network (WSN). In many WSN applications, users can not only monitor the area or object to obtain information, but also can make information processing and control of a particular object. Different from the traditional wireless sensor networks and wireless Ad-hoc network, WSN is of resources and communication ability limited. Therefore, to prolong the network life cycle, application of energy efficiency optimization throughout the network design is a key issue.Routing protocol design of WSN is a key technology, an effective routing algorithm can well optimize network energy consumption and prolong the network life cycle. At present, many studies have been completed design in a limited energy supply, the sensor nodes can effectively send and receive data routing protocol.In this paper, we first discussed some existing WSN routing protocol. Then using NS2 software to simulate energy consumption performance of some typical routing algorithm, and has done analysis and discussion. And then, we use a novel routing algorithm to disseminate information via multiple paths in static and energy-constrained WSN, considering the node interference problems, and set the interference of nodes and the nodal communication radius scope is equal. The algorithm consists of a node-disjoint multipath search protocol and a load balancing algorithm, can find many node-disjoint routes from source to sink, and obtain the load balancing. Simulation results show that the algorithm can effectively reduce the nodes of the energy consumption, balance network energy consumption and prolong network lifetime.
