Available in PDF, EPUB and Kindle. Book excerpt: Traditional routing protocols cannot provide a seamless connectivity in a highly dynamic and dense mobile ad hoc network of UAV (unmanned aerial vehicles) nodes, due to frequent link breaks, high congestion and the quality of service (QoS) demands of time-sensitive and high data-rate data delivery. In addition, the control overhead and delay increase significantly in these schemes with the increase in the network size. Proactive routing algorithms, such as the OLSR (optimized link state routing) protocol, are widely used in the literature to accommodate strict demands on time-bound data delivery. OLSR maintains routes to all reachable nodes in the network which minimizes the route discovery time, but incurs a huge control overhead. To address this issue, we propose two algorithms which reduce the control traffic overhead at the cost of a minimal drop in PDR (packet delivery ratio) as compared to the standard OLSR protocol. It is observed that the routing schemes which use multiple metrics for the route selection can significantly improve the QoS of the flow as compared to the single-metric (i.e., shortest hop) based route selection schemes, such as OLSR. Furthermore, they can provide quality-aware routes for complex scenarios where flows may have time-varying QoS requirements. Therefore, we have proposed a routing scheme using the hop count, residual link lifetime and buffer occupancy. Our scheme outperforms the standard OLSR protocol in every tested scenario, including medium and high node mobility with low, medium and high degree of congestion. Furthermore, our proposed scheme uses only 1-hop information for the route selection which significantly reduces the overhead and delay as compared to those multi-metric based routing schemes which require global knowledge for their route selection.

Available in PDF, EPUB and Kindle. Book excerpt: Relying on unmanned autonomous flight control programs, unmanned aerial vehicles (UAVs) equipped with radio communication devices have been actively developed around the world. Given their low cost, flexible maneuvering and unmanned operation, UAVs have been widely used in both civilian operations and military missions, including environmental monitoring, emergency communications, express distribution, even military surveillance and attacks, for example. Given that a range of standards and protocols used in terrestrial wireless networks are not applicable to UAV networks, and that some practical constraints such as battery power and no-fly zone hinder the maneuverability capability of a single UAV, we need to explore advanced communication and networking theories and methods for the sake of supporting future ultra-reliable and low-latency applications. Typically, the full potential of UAV network’s functionalities can be tapped with the aid of the cooperation of multiple drones relying on their ad hoc networking, in-network communications and coordinated control. Furthermore, some swarm intelligence models and algorithms conceived for dynamic negotiation, path programming, formation flight and task assignment of multiple cooperative drones are also beneficial in terms of extending UAV’s functionalities and coverage, as well as of increasing their efficiency. We call the networking and cooperation of multiple drones as the terminology ‘flying ad hoc network (FANET)’, and there indeed are numerous new challenges to be overcome before the idespread of so-called heterogeneous FANETs. In this book, we examine a range of technical issues in FANETs, from physical-layer channel modeling to MAC-layer resource allocation, while also introducing readers to UAV aided mobile edge computing techniques.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents the Forecasting Routing Technique (FORTEL), a routing protocol for Mobile Ad-Hoc Networks (MANETs) based on the nodes' Location Information. FORTEL stores the nodes' location information in the Location Table (LT) in order to construct routes between the source and the destination nodes. FORTEL follows the source routing strategy, which has rarely been applied in position-based routing. According to the source routing strategy, the end-to-end route is attached to the packet, therefore, the processing cost, in regards to the intermediate nodes that simply relay the packet according to route, is minimized. FORTEL's key mechanisms include: first, the location update scheme, employed to keep the LT entries up-to-date with the network topology. Besides the mobility variation and the constant rate location update schemes applied, a window location update scheme is presented to increase the LT's information accuracy. Second, the switching mechanism, between "Hello" message and location update employed, to reduce the protocol's routing overhead. Third and most important is the route computation mechanism, which is integrated with a topology forecasting technique to construct up-to-date routes between the communication peers, aiming to achieve high delivery rate and increase the protocol robustness against the nodes' movement. FORTEL demonstrates higher performance as compared to other MANET's routing protocols, and it delivers up to 20% more packets than AODV and up to 60 % more than DSR and OLSR, while maintaining low levels of routing overhead and network delay at the same time. The effectiveness of the window update scheme is also discussed, and it proves to increase FORTEL's delivery rate by up to 30% as compared to the other update schemes. A common and frequently occurring phenomenon, in wireless networks, is the Hidden Terminal problem that significantly impacts the communication performance and the efficiency of the routing and MAC protocols. Beaconless routing approach in MANETs, which delivers data packets without prior knowledge of any sort Hof information, suffers from packet duplication caused by the hidden nodes during the contention process. Moreover, the throughput of the IEEE MAC protocol decreases dramatically when the hidden terminal problem occurs. RTS/CTS mechanism fails to eliminate the problem and can further degrade the network's performance by introducing additional overhead. To tackle these challenges, this thesis presents two techniques, the Sender Suppression Algorithm and the Location-Aided MAC, where both rely on the nodes' position to eliminate packet duplication in the beaconless routing and improve the performance of the 802.11 MAC respectively. Both schemes are based on the concept of grouping the nodes into zones and assign different time delay to each one. According to the Sender Suppression Algorithm, the sender's forwarding area is divided into three zones, therefore, the local timer, set to define the time that the receiver has to wait before responding to the sender's transmission, is added to the assigned zone delay. Following the first response, the sender interferes and suppresses the receivers with active timer of. On the other hand, the Location-Aided MAC, essentially a hybrid MAC, combines the concepts of time division and carrier sensing. The radio range of the wireless receiver is partitioned into four zones with different zone delays assigned to each zone. Channel access within the zone is purely controlled by CSMA/CA protocol, while it is time-based amongst zones. The effectiveness of the proposed techniques is demonstrated through simulation tests. Location-Aided MAC considerably improves the network's throughput compared to CSMA/CA and RTS/CTS. However, remarkable results come when the proposed technique and the RTS/CTS are combined, which achieves up to 20% more throughput as compared to the standalone RTS/CTS. Finally, the thesis presents a novel link lifetime estimation method for greedy forwarding to compute the link duration between two nodes. Based on a newly introduced Stability-Aware Greedy (SAG) scheme, the proposed method incorporates the destination node in the computation process and thus has a significant advantage over the conventional method, which only considers the information of the nodes composing the link.

Book excerpt: ABSTRACT: Wireless networks play a significant role in communication systems because of the advantages of flexible access and relatively low deployment cost. Among various wireless networks classified according to structures, wireless ad hoc networks and wireless sensor networks share the same feature of no infrastructure. Although the two types of wireless networks offer a variety of applications in military, civil and research areas, they also pose many unique challenging issues. Due to the shared wireless medium, fragile wireless links, constrained power resource, limited computation capability and dynamic topologies, delay bounded reliable packet delivery from a source to the destination is a tough problem in both wireless ad hoc networks and wireless sensor networks. In this dissertation, we attempt to address some methods to solve some routing problems in mobile ad hoc network (MANET), and wireless sensor networks (WSN).

Available in PDF, EPUB and Kindle. Book excerpt: In the second part of this dissertation, we turn our attention to the problem of reliable and trustworthy routing in mobile ad hoc networks. We consider the implications of applying our spatial approach to improve routing reliability through difficult terrains with possibly untrustworthy regions in tactical mobile ad hoc networks. The proposed approach provides maps of spatial reliability and trust, that reflect the probabilities for finding trustworthy routes between distinct locations. We develop a routing protocol, named "Reliability Map Routing" (RMR), which discovers routes over spatial cells whose local reliability and trust metrics are distributed throughout the network via a fast dissemination algorithm. Furthermore, the RMR protocol is capable of reliable geocasting with low overhead. Via QualNet simulation studies, we compare the performance of the RMR protocol in terms of packet delivery ratio, delay, and overhead, and quantify the effects of node density, velocity, and traffic load on these performance metrics.
