Abstract

Routing protocol for low-power and lossy networks (RPL) is the standard IPv6 based routing protocol for low power, lossy Networks (LLNs) proposed by IETF. It is proposed for networks with characteristics like small packet size, lossy links, low bandwidth, low data rate and low power resources. RPL is a single path routing protocol and the existing objective functions do not support creation of multiple routing paths between source and destination. Multipath routing can be used to achieve multifold objectives, including higher reliability, increased throughput, fault tolerance, congestion mitigation and hole avoidance. In this paper, M-RPL a multi-path extension of RPL is proposed that aims to provide temporary multipath routing during congestion over a path. Congestion is primarily detected by a forwarding node by monitoring packet delivery ratio and is mitigated by providing partially disjoint multipath routing. Detailed simulation analysis of M-RPL against RPL shows that using multi-path RPL reduces congestion and increases the overall throughput. Hence M-RPL is suitable for supporting high data rates as compared to single path RPL.

用于低功耗网络的多路径RPL

低功耗损耗网络路由协议(Routing protocol for low-power and lossy networks, RPL)是IETF提出的基于IPv6的低功耗损耗网络(lln)标准路由协议。它适用于数据包小、链路有损、带宽低、数据速率低、资源功耗低的网络。RPL是一种单路径路由协议，现有的目标函数不支持在源和目的之间创建多条路由路径。多路径路由可用于实现多重目标，包括更高的可靠性、更高的吞吐量、容错性、拥塞缓解和避免漏洞。M-RPL是RPL的一种多路径扩展，其目的是在路径拥塞期间提供临时的多路径路由。拥塞主要是由转发节点通过监控数据包传送率来检测，并通过提供部分不相交的多路径路由来缓解。对M-RPL和RPL的详细仿真分析表明，使用多路径RPL可以减少拥塞，提高总体吞吐量。因此，与单路径RPL相比，M-RPL适合支持高数据速率。
