“…This approach does not involve any improvement to RPL as a protocol. Similar to the last approach, the authors in [9] present a strategy for mobile sinks in IPv6 WSNs. In this strategy, every node calculates its weight based on three metrics: number of hops, residual energy and number of neighbour nodes.…”

Abstract-The Routing Protocol for Low Power and Lossy Networks (RPL) has become the standard routing protocol for the Internet of Things (IoT). This paper investigates the use of RPL in dynamic networks and presents an enhanced RPL for different applications with dynamic mobility and diverse network requirements. This implementation of RPL is designed with a new dynamic Objective-Function (D-OF) to improve the Packet Delivery Ratio (PDR), end-to-end delay and energy consumption while maintaining low packet overhead and loop-avoidance. We propose a controlled reverse-trickle timer based on received signal strength identification (RSSI) readings to maintain high responsiveness with minimum overhead and consult the objective function when a movement or an inconsistency is detected to help nodes make an informed decision. Simulations are done using Cooja with random waypoint mobility scenario for healthcare applications considering multi-hop routing. The results show that the proposed dynamic RPL (D-RPL) adapts to the nodes mobility and has a higher PDR, slightly lower end-to-end delay and reasonable energy consumption compared to related existing protocols.

“…Examples of modifications to RPL for these purposes can be found in [10,11]. However, since these solutions focus on traffic flows to mobile gateways without support for mobile end-devices, we consider these as out-ofscope for this paper.…”

The "routing protocol for low-power and lossy networks" (RPL) from the IETF ROLL working group is a widely used standard to support routing in wireless sensor networks (WSNs). Although the RPL protocol was originally designed with static topologies in mind, recently a number of extensions have been proposed to support traffic flows from mobile nodes towards a static gateway. However, this paper demonstrates that these solutions do not support traffic flows going the other direction, for example, from the gateway towards mobile devices. To remedy this, the paper first analyses the problems that prevent reliable traffic flows towards mobile devices when using RPL. Afterwards, a new mechanism to improve downward route updating is proposed. Our new approach minimizes the probability of connectivity loss by ensuring that the internal state of the static network remains consistent. Our solution is implemented and evaluated using both simulation tools and experimental facilities and it is shown that it improves the end-to-end packet delivery ratio to mobile nodes from 20-30% up to 80% while reducing the overall RPL signalling overhead without the use of location information.

“…The issues of mobile connection and route have to be solved in a mobility scheme. Some researchers conducted research on the connection issues in mobility management [22,23], and some studies focus on mobile route problems [24,25]. However, there are researchers [9] doubt whether the energy saved by mobility scheme can cover the power consumed by mobility.…”

By way of reducing the active time of sensor nodes, this paper proposed an energy efficient data convergence model which is adaptable for cold chain application. The model runs on hierarchical wireless sensor network architecture, which aims at finding an optimal sleep/wake up schedule that can coordinate the data sending time slot for both cluster nodes and routing nodes. It can avoid data retransmission caused by sending conflict. Especially, in this model, we work on preventing the energy consumed by unnecessary broadcast listening between adjacent clusters. Simulation results show our model runs with a lower active time compared with the similar scheme.
