Improvement and implementation of RPL routing protocol in wireless sensor networks

RPL is an IPv6 routing protocol arming at low power consumption lossy networks, which is very important to the development of wireless personal area network. By studying the discovery mechanism of RPL routing protocol in wireless sensor networks, we found that advantage routing nodes may die prematurely due to excessive use in current RPL mechanisms, which can cause the entire network life cycle greatly shortened. To address this problem, the energy balance scheme is put forward which uses the energy consumption as a parameter of measurement to improve the objective function of the optimal path selection strategy. Finally, we implement and test the effectiveness of the improved scheme.
