Abstract
An IPv6 routing protocol for low power and lossy networks provides an IPv6 communication for a wide range of applications in multi-hop mesh networks. The routing protocol for low power and lossy networks defines the creation and management of downward routes with two modes of operations: storing and non-storing modes. The storing and non-storing modes have weaknesses for memory constraints and packet traffic overheads, respectively. The storing mode may cause routing failures due to constraints on memory in routers and the non-storing mode may cause packet fragmentation that can become a factor for packet delays or loss. Then the problems may degrade the downward route performance in routing protocol for low power and lossy networks. Therefore, in this article, we propose a hybrid mode that combines the advantages of the existing two modes to improve the performance of downward packet transmission in routing protocol for low power and lossy networks networks. The proposed hybrid mode uses a new routing header format. The routing information for packet delivery is distributed with the extended routing header. We implement the proposed hybrid mode in Contiki OS environment to compare with existing techniques. From the experiment, it was observed that the proposed hybrid mode can improve the performance of downward packet transmission. Therefore, with the proposed hybrid mode, it is possible to configure a network enable to be composed of many leaf nodes with constrained memory. We also discuss future works.
Highlights
Low power and lossy networks (LLNs), referred to as wireless sensor networks (WSNs), have been constantly studied over the past decade
RPL nodes in a Destination-Oriented Directed Acyclic Graph (DODAG) can be classified into two different types of nodes based on routing capability: routers and leaf nodes
All the routing information for leaf nodes are stored in a DODAG root like the non-storing mode but the information except for leaf nodes is collected in RPL routers
Summary
Low power and lossy networks (LLNs), referred to as wireless sensor networks (WSNs), have been constantly studied over the past decade. The packet from a DODAG root toward node A::4 is transmitted via nodes A::1 and A::3 referenced by routing information stored in routers.
