Abstract:The RPL protocol is a routing protocol for low power and lossy networks. In such a network, energy is a very scarce resource; so many studies are focused on minimizing global energy consumption. End-to-end latency is another important performance indicator of the network, but existing research tends to focus more on energy consumption and ignore the end-to-end delay of data transmission. In this paper, we propose a kind of energy equalization routing protocol to maximize the surviving time of the restricted nodes so that the energy consumed by each node is close to each other. At the same time, a multi-path forwarding route is proposed based on the cache utilization. The data is sent to the sink node through different parent nodes at a certain probability, not only by selecting the preferred parent node, thus avoiding buffer overflow and reducing end-to-end delay. Finally, the two algorithms are combined to accommodate different application scenarios. The experimental results show that the proposed three improved schemes improve the reliability of the routing, extend the lifetime of the network, reduce the end-to-end delay, and reduce the number of DAG reconfiguration.

Abstract-IPv6 over low power wireless personal area network (6LoWPAN) is promising to be used in many different IoT applications. Recently, many protocols have been proposed for 6LoWPAN networks such as RPL routing protocol which is developed by the ROLL working group and expected to be the standard routing protocol for 6LoWPAN. Many problems are facing 6LoWPAN as it connects to the Internet such as congestion. In this paper, we propose a new RPL routing metric called Buffer Occupancy which reduces the number of lost packets due to buffer overflow when congestion does occur. Also, a new RPL objective function called Congestion-Aware Objective Function (CA-OF) is presented. The proposed objective function works efficiently when congestion occurs by selecting less congested paths. Simulation results show that CA-OF improves performance in the presence of congestion by an overall average of 37.4% in term of number of lost packets, throughput, packet delivery ratio and energy consumption.

“…Such as mETX, ETT, WCEETT, etc [7]. Some researchers have also tried different method to optimize routing metrics and Object Functions for RPL, to meet different requirements in certain application scenarios [8] [9] [10]. The optimization scheme here is also inspired by the research results before.…”

Routing Protocol for Low-Power and Lossy Networks (RPL) is the Internet Engineering Task Force (IETF) standard for IPv6 routing in Low-power and Lossy Networks (LLNs). By using the Objective Function (OF) and a collection of routing metrics, it can build a Destination Oriented Directed Acyclic Graph (DODAG). There are two kinds of OFs specified by the IETF, Objective Function Zero (OF0) and Minimum Rank with Hysteresis Objective Function (MRHOF) respectively. The former is based on minimum hop count while the latter is based on Expected Transmission Count (ETX) and is more preferable.However, as the network size increases, both MRHOF and OF0 will introduce long single hop, which may become the routing bottleneck that restricts the entire network. In this paper, the problem is solved by optimizing the MRHOF with a new routing metric, the PER-HOP ETX. Instead of working with additive ETX metrics along a route, PER-HOP ETX distributes the ETX value to each node along the route. This method can achieve better routing performance in large-scale sensor network scenario. A detailed mathematical proof is given in the paper, and simulations were carried out based on the Contiki operating system. Experiments showed that PER-HOP ETX, the proposed optimization outperforms OF0 and ETX in terms of network latency, packet delivery ratio and energy consumption when the network scale becomes large.
