RPL:Low Memory Cost RPL Routing Protocol
发布时间：2018-08-11 06:48
The RPL routing protocol is widely used in low-power and lossy networks (LLNs).However,the storing mode of RPL is criticized for large memory consumption.In this paper,an advanced RPL was proposed,called B-RPL,which reduces the memory cost by making routing decision according to a set of destinations rather than the routing table used in the raw RPL.Further more,the B-RPL employs Bloom filter to manage the set of destinations,so that the memory consumption becomes extremely low.The B-RPL also contains several adaptive designs specially tailored for dynamic network change in LLNs.Experiments show that,comparing with RPL in storing mode,B-RPL saves 97.8% storage at the expense,and only increases 2.4% transmission overhead.
