Multipath Routing Protocol for DAG-based WSNs with Mobile Sinks

摘要：

　　Low power and Iossy networks have been an active area of research.Numerous protocols have been proposed for routing in these networks using metrics like hop count,delay,bandwidth etc.The IETF ROLL group has proposed a proactive gradient protocol called RPL.However,for a network with few mobile sinks calculating gradients using proactive approach is not energy efficiency.This paper proposed a multipath routing protocol for Wireless Sensor Networks with mobile sinks,called MDMR.Directed Acyclic Graphs (DAGs) are required for WSNs organization because of their route redundancy to the root.MDMR is based on RPL framework.By broadcasting DAG construction messages including metrics,such as,hop count,node energy and link quality indication,protocol constructs DAG and provides path redundancy.This allows nodes to find multiple alternative paths easily while link failures.
