The traditional wireless sensor network (WSN) that its own characteristics determine its various Properties Limited, the traditional sensor networks and wireless multimedia network (WMSNs) high-speed real-time data transmission in sensor network application development is a hot topic in academic research. Routing in high speed sensor network determines the working mode and the efficiency of the energy of the nodes, so how to design wireless sensor network routing protocol, energy efficiency is one of the important direction of the research on wireless sensor network.This topic research content "The key technology of Medium and High rate sensor network ","RFID sensor network key problem research" research project as the background, focuses on the analysis of the project of sensor nodes in the unbalance energy consumption reasons, which caused a node in a high speed sending and receiving data in sensor networks, resulting in sensor nodes excessive energy consumption, rapid death, but other node having many residual energy problem.In view of the above problems, this article mainly completed the following work:1. First analyzes the characteristics of Medium and High rate sensor network, as well as to the energy balance of cross-layer optimization of multi-hop routing protocol. And analyzed the various energy efficient routing protocol, their advantages and disadvantages, domestic and foreign energy efficient routing protocol research.2. The laboratory practical project of Medium and High rate sensor network was introduced, and the high efficiency of the sensor network routing protocol is extracted from the project of high speed in sensor networks, energy saving of proposition, and makes a detailed study of this proposition.3. Based on energy balancing routing protocol is proposed on the routing protocol, cross-layer optimization, the network protocol layer of various sensors are analyzed, and the mechanism of interaction of various protocols, and energy efficiency of the routing protocol, cross-layer optimization is analyzed.4. In wireless sensor networks combined the advantages of energy balancing routing protocols and cross layer optimization routing protocol proposed energy balanced cross-layer optimization multiple-hops routing protocols, and proposed multihop factor μ, and multi-hop factor μ as a measure of the residual energy of cluster head nodes to make a reasonable judgment on its forwarding data, through multi-hop factors that cannot be cluster head nodes with low energy forwarding information to the base station, so as to balance the energy consumption of the whole network, further optimization of the sensor network node lifetime. Simulation results show that, the routing protocol can balance the energy consumption of the entire sensor network, greatly prolong the lifetime of wireless sensor networks.In this article a new energy-balanced cross-layer optimization of wireless sensor networks routing protocol to achieve the energy consumption of sensor nodes is balanced, prevent because sensor networks in reducing the energy consumption of wireless sensor network node utilization maximization. In order to balance the cross-layer optimization of wireless sensor networks based on energy multi-hop routing protocol so that all the nodes in sensor networks energy have been fully utilized prolongs the life of the whole sensor network. Finally, through high speed sensor network system laboratory of theoretical results are verified, and achieved good results, provides certain reference value for the study of routing protocols in sensor networks of high speed.
