An Algorithm of Wireless Sensor Network Based on Free Space Optical Communication

Abstract

The hierarchical distributed network topology combined with traditional wireless routing algorithm is adopted and improved by through introducing energy model of FSO sensor network to study the method of extend network nodes life in special occasion. The OEEMRP protocol (Optical Efficient Energy Multi-Path Routing Protocol) is also proposed. The protocol also can save the node energy and improve the network survival time. In the simulation, we compare and analyze performance difference of death node number and residual energy in LEACH and OEEMRP algorithm. The result shows that improved routing algorithm can make network node more intensive, and in the condition of large network size, the performance will be improved significantly. In a word, it has significant role in network communication.
