TL;DR: The proposed protocol is the first geographic routing protocol for underwater sensor networks that considers the sensor node vertical movement ability to move it for topology control purpose and achieves more than 90% of data delivered even in hard and difficult scenarios of very sparse or very dense networks.
Abstract: Underwater sensor networks have recently been proposed as a way to observe and explore the lakes, rives, seas, and oceans. However, due to characteristics of the acoustic medium, efficient protocols for delivering data must exist. In this work, we propose a novel geographic routing protocol with network topology control for underwater sensor networks, that adjusts the depth of the nodes in order to organize the network topology for improving the network connectivity and forward data where the greedy geographic routing fail. The proposed protocol is the first geographic routing protocol for underwater sensor networks that considers the sensor node vertical movement ability to move it for topology control purpose. The simulation results show that, with the topology control, the fraction of disconnected nodes and nodes located into communication void regions, are drastically reduced and consequently the delivered data rate is improved. It achieves more than 90% of data delivered even in hard and difficult scenarios of very sparse or very dense networks.

TL;DR: The proposed routing protocol embeds the multi-layer parameters into the routing algorithm, thus combining the authentication and routing processes without incurring significant overheads, and saving resources by maintaining smaller routing information.
Abstract: This paper introduces a multi-hop routing protocol that enables secured IoT devices' communication. The routing protocol enables the IoT devices to authenticate before forming a new network or joining an existing network. The authentication uses multi-layer parameters to enhance the security of the communication. The proposed routing protocol embeds the multi-layer parameters into the routing algorithm, thus combining the authentication and routing processes without incurring significant overheads. The multi-layer parameters include a unique User-Controllable Identification, users' pre-agreed application(s), and a list of permitted devices, thus saving resources by maintaining smaller routing information. Experimental and field tests were conducted with results showing that our secure multi-hop routing is suitable to be deployed for IoT communication.

TL;DR: An improved routing algorithm of control overhead that uses Cluster-Tree parameter of ZigBee network and network addresses of destination nodes to control the transmission range and restrict its transmission direction is proposed.
Abstract: Control overhead is a very important indicator for measure performance of ZigBee routing protocol. More control overhead will add network energy consumption and reduce network survival time. By analyzing the architecture features of ZigBee network and the key technologies of network layer, researching ZigBee routing protocol based on ZigBee Cluster-Tree network architecture, an improved routing algorithm of control overhead is proposed. The algorithm uses Cluster-Tree parameter of ZigBee network and network addresses of destination nodes to control the transmission range and restrict its transmission direction. The algorithm performance is simulated by NS-2 simulator. The simulating results indicate that control overhead is reduced about a half without influencing packet delivery ratio and path length of ZigBee network.

TL;DR: Experiments demonstrate that adding link breakage prediction to DSR can significantly reduce the total number of dropped data packets and the proactive route maintenance does not cause significant increase in average packet latency and average route length.
Abstract: Most existing on-demand mobile ad hoc network routing protocols continue using a route until a link breaks. During the route reconstruction, packets can be dropped, which will cause significant throughput degradation. In this paper, we add a link breakage prediction algorithm to the dynamic source routing (DSR) protocol. The mobile node uses signal power strength from the received packets to predict the link breakage time, and sends a warning to the source node of the packet if the link is soon-to-be-broken. The source node can perform a pro-active route rebuild to avoid disconnection. Experiments demonstrate that adding link breakage prediction to DSR can significantly reduce the total number of dropped data packets (by at least 20%). The tradeoff is an increase in the number of control messages by at most 33.5%. We also found that the proactive route maintenance does not cause significant increase in average packet latency and average route length. Enhanced route cache maintenance based on the link status can further reduce the number of dropped packets.
