Much attention has been focused lately on the Opportunistic Routing technique (OR) that can overcome the restrictions of the harsh underwater environment and the unique structures of the Underwater Sensor Networks (UWSNs). OR enhances the performance of the UWSNs in both packet delivery ratio and energy saving. In our work; we propose a new routing protocol; called Energy Efficient Depth-based Opportunistic Routing with Void Avoidance for UWSNs (EEDOR-VA), to address the void area problem. EEDOR-VA is a reactive OR protocol that uses a hop count discovery procedure to update the hop count of the intermediate nodes between the source and the destination to form forwarding sets. EEDOR-VA forwarding sets can be selected with less or greater depth than the packet holder (i.e., source or intermediate node). It efficiently prevents all void/trapped nodes from being part of the forwarding sets and data transmission procedure; thereby saving network resources and delivering data packets at the lowest possible cost. The results of our extensive simulation study indicate that the EEDOR-VA protocol outperforms other protocols in terms of packet delivery ratio and energy consumption

Usually, the nodes in Mobile Adhoc Networks (MANET) are bounded with the limited power resources to interact with each other nodes without any backbone infrastructures. As a result, an allocation of unbalanced traffic among nodes may increase the power dissipation in the overloaded nodes and path failures that degrade the network lifetime. To tackle this problem, an on-demand Power and LoadAware (PLA) multipath node-disjoint source routing scheme was proposed based on the Dynamic Source Routing (DSR) protocol that uses a new cost function to determine the multiple nodedisjoint power and select the load-aware optimal paths to their destinations. However, this protocol was affected by control overhead and the reliable packet delivery was also not effective. Hence in this article, Power and Load-aware i.e., Utility-Aware Reliable Opportunistic Routing (UAROR) protocol is proposed to enhance the efficiency and reliability of the routing protocol. In this protocol, topology control and link lifetime prediction algorithms are integrated into the PLA algorithm to predict the effect of the node mobility on routing performance. The link prediction algorithm considers both mobility speed and direction for improving the accuracy. As well, an opportunistic topology control algorithm uses packet delivery ratio to maintain the node’s stability. Moreover, Utility-Aware Enhanced ROR (UAEROR) protocol is proposed to improve the node’s stability and reduce the control overhead by employing the neighbor detection algorithm that uses degree and reachability of nodes. Finally, the simulation results show that the effectiveness of the proposed protocol compared to the existing protocol in terms of throughput, end-to-end delay, packet delivery ratio, network lifetime, energy consumption and control overhead

Energy Efficient Routing

The lifetime of a node in wireless sensor networks (WSN) is directly responsible for the longevity of the wireless network. The routing of packets is the most energy-consuming activity for a sensor node. Thus, finding an energy-efficient routing strategy for transmission of packets becomes of utmost importance. The opportunistic routing (OR) protocol is one of the new routing protocol that promises reliability and energy efficiency during transmission of packets in wireless sensor networks (WSN). In this paper, we propose an intelligent opportunistic routing protocol (IOP) using a machine learning technique, to select a relay node from the list of potential forwarder nodes to achieve energy efficiency and reliability in the network. The proposed approach might have applications including e-healthcare services. As the proposed method might achieve reliability in the network because it can connect several healthcare network devices in a better way and good healthcare services might be offered. In addition to this, the proposed method saves energy, therefore, it helps the remote patient to connect with healthcare services for a longer duration with the integration of IoT services.
