Research On Routing Protocol Of Wireless Sinsor Networks

Wireless sensor networks are considered to be the 21st century, one of the most important technologies, which can sense the surrounding environment, to a variety of environmental information collected to send to the user, and because low-cost wireless sensor network node, low power consumption characteristics, so that it can a wide range of land sown in a certain area, even if humans can not reach the area. Therefore, wireless sensor networks have broad application prospects, but also to human lives will be far-reaching implications.Wireless sensor networks and traditional wireless network routing protocol design have a different design goals. Traditional wireless networks, or mobile Ad hoc network routing protocol design of the main purpose is to improve service quality, equitable and efficient use of network bandwidth, end to end to find the minimum delay path, improve network utilization and avoid network congestion, as well as a balanced network traffic and so on, energy consumption is not the main focus of consideration; the large number of wireless sensor network node, the energy limited and energy is not easy to supplement or replace the dynamic changes of network topology will have to consider the integration of data processing technology. Therefore, the wireless sensor network routing protocol design The main objective is to ensure that data under the premise of a normal extension of the network as much as possible the survival time.Wireless sensor networks and traditional wireless network routing protocol design has a different design this routing protocol design of hardware nodes are self-designed, wireless sensor network node AVR series of microprocessors is the most powerful Atmegal28 microcontroller, wireless communication module is Norway's Nordic Company introduction of a single-chip RF chip nRF905. Sensor nodes are dormant most of the time, regular data collection, collected the data package sent through the radio antenna, the whole process time is very short, has been dealt with quickly re-enter the sleep state, tremendous savings in energy consumption. In addition, in order to avoid broadcast storms and the impact of information overlap, using mechanisms for the registration packet, thereby saving energy.
