The Research On Wireless Sensor Network Routing Algorithm Based On Negotiation

With the progress of technology and culture, the way of people accessing toinformation has increased conveniently and diversified. The network as the mainmedium of accessing and transmitting information is also constantly developed tomeet the people’s growing demand of informing. A variety of new wirelesscommunication technology has emerged. Wireless sensor networks as researchfocus of the next-generation network has aroused concern. Wireless sensornetworks consist of small nodes with sensing, computation, and wirelesscommunications capabilities. Perceiving the physical world at anytime andanywhere, then returning the required data is the greatest feature of WSNs.The sensor node’s battery capacity, memory and computing power are verylimited of wireless sensor networks, topological dynamic change, traditionalwireless routing protocol is not fit wireless sensor networks. How to design therouting protocol of low energy consumption, fit topological dynamic change,improving network reliability and stability has become a current research hotspot.Flooding protocol is the most classic of the wireless sensor networking routingprotocols. Flooding protocol is the most classic of the wireless sensor networkrouting protocols The SPIN protocol is improved for the use of resources is blindly,overlay, implosion in the packet data transmission of Flooding protocol., transmitdata on negotiation, compare to Flooding protocol SPIN protocol data distributionefficiency has been improved. The sensor nodes send collected data to the Sinknode, non-directional, large amounts of data to be forwarded to the Sink node in theopposite direction, wasting energy and extend the data transmission delay inwireless sensor networks of SPIN protocol. The protocol is improved because ofthe lack of SPIN protocol and the single-Sink and multi-Sink were discussed. Firstuse the minimum number of hops to confirm that the minimum number of hops ofthe node to reach the Sink node. During the negotiation phase based on the currentenergy and the minimum number of hops to control the data direction ofpropagation, select the path that is real-time performance better to the Sink node.Finally, this dissertation use NS2to complete the simulation experiment in thesame simulation environment respectively. Single Sink node-based and based on the improvements of more than the Sink node SPIN protocol can reduce the numberof packets in the transfer process, thereby reducing network energy consumptionand prolong the network life cycle.
