A Study Of Balanced Energy Consumption Of RPL Routing Protocol Based On Contiki Operating System

At present,the Wireless Sensor Network(WSN) is widely used,such as medical, military、agriculture、forest fire detection and smart home,it can well for monitoring and tracking tasks.But the nodes in WSN usually have low cost,low power consumption and the simple structure,and these nodes use batteries to working,due to the particularity of working environment ,once the battery is finished,replacing the battery is unlikely.therefore,in order to completing the monitoring tasks better,reducing energy consumption of nodes and prolonging the life cycle of network is an important task of WSNs.This paper is mainly studied the following aspects:(1)The first, the background and significance is studied,and study the routing protocol for the low power and lossy network(RPL),understanding control of network news and networking process.With existing hardware of the lab and caught software,we analysis control message module.(2)Secondly,we analysis the existing RPL routing protocol in energy issues,and put forward the method to reduce energy consumption of nodes,then improve it in the target function OF0.(3)Finally,we use the recent very popular Contiki operating system and Cooja simulation software as our experiment platform to verify this improvement in energy.Through energy improvement of RPL routing protocol,and compared with the original routing protocol,the experimental results show that it is feasible that via switching nodes forward data path to reduce energy consumption.The average energy consumption of nodes effectively avoid network "empty",and extend the life of network.
