Abstract:
Ad hoc on-demand distance vector (AODV) is one of the commonly used reactive routing protocols in mobile ad hoc network (MANET) as it can achieve relatively better communication performance. However, AODV can lead to heavy routing overhead and additional delay due to the flooding broadcast of route request (RREQ) packets during the route discovery cycle. Additionally, the multiple route reply (RREP) packets in response to a single RREQ can also contribute to overhead and additional delay. Thus, a new algorithm called Less Flooding-AODV (LF-AODV) was proposed to reduce the broadcasted RREQ and

Abstract:
A vehicular ad hoc network (VANET) is a technology in which moving cars are used as routers (nodes) to establish a reliable mobile communication network among the vehicles. Some of the drawbacks of the routing protocol, Ad hoc On-Demand Distance Vector (AODV), associated with VANETs are the end-to-end delay and packet loss. We modified the AODV routing protocols to reduce the number of route request (RREQ) and route reply (RREP) messages by adding direction parameters and two-step filtering. The two-step filtering process reduces the number of RREQ and RREP packets, reduces the packet overhead

Ad hoc on demand distance vector routing protocol has been specially designed for mobile ad hoc networks by reducing the overhead.

With the dawn of Internet of Things (IoT), interconnected things and smart applications have significantly reduced human intervention in accomplishing tasks. Yet, due to its openness, heterogeneity, limited resources and extensiveness, it suffers from several issues such as lesser capacity links, energy consumption, resource optimization etc. Routing of packets in such constrained environment is yet challenging.

Abstract:
Mobile ad hoc networks (MANETs) are wireless networks that operate without a fixed infrastructure or base station. In MANETs, each node acts as a data source and a router, establishing connections with its neighboring nodes to facilitate communication. This research has introduced the Enhanced Hybrid Routing Protocol (EHRP), which combines the OLSR, AOMDV, and AODV routing protocols while considering the network situation for improved performance. The EHRP protocol begins by broadcasting a RREP (Route Reply) packet to discover a route. The selection of routing options is based on the current n

Abstract:
Without the need of a fixed foundation or base station, the Mobile Ad hoc Network creates its own wireless network. One of the most troublesome aspects of Mobile Ad hoc Network (MANET) is the occurrence of unexpected loss of network connectivity. As a result of this problem, packets continue to drop, and we must restore the connection by sending Route Request (RREQ) and Route Reply (RREP). As a result, network performance will suffer yet another setback. We used the scenario routing technique to combine the Dream Multipath Routing (DMR), Ad hoc on-demand multipath distance vector (AOMDV), Opti

Abstract:
Request route flooding attack is one of the main challenges in the security of Mobile Ad Hoc Networks (MANETs) as it is easy to initiate and difficult to prevent. A malicious node can launch an attack simply by sending an excessively high number of route request (RREQ) packets or useless data packets to nonexistent destinations. As a result, the network is rendered useless as all its resources are used up to serve this storm of RREQ packets and hence unable to perform its normal routing duty. Most existing research efforts on detecting such a flooding attack use the number of RREQs originated

This paper analyzes the impact of RREQ packet flooding on WSNs through simulations. WSNs are vital for applications like surveillance, healthcare, and environmental monitoring. However, they are susceptible to DoS attacks, such as RREQ packet flooding, which disrupts normal operations by overwhelming the network with excessive route requests. The study evaluates the effect of RREQ flooding on WSN performance metrics, including throughput, end-to-end delay, packet delivery ratio, energy consumption, and routing load.

Abstract:
This paper deals with security of routing protocols of Mobile Ad hoc Networks (MANETs), and proposes a solution to immunize such protocols against packet dropping misbehavior. Most of the current secure protocols are vulnerable to packet dropping misbehavior, which can be exploited by selfish nodes and malicious ones as well. For example, simply by dropping RREQ (Route Request) packets a selfish node can exclude itself from routes and thereby avoid receiving data packets to forward. On the other hand, a malicious node can drop RERR (Route Error) packets to keep the use of failed routes, possib

Abstract:
The authors propose a beaconless, on-demand, mobile ad hoc network routing protocol called minimum interference based routing protocol (MIF) that minimizes the end-to-end delay per data packet. During route discovery, each node inserts its identification and location information before broadcasting the Route-Request (RREQ) message in its neighborhood. The weight of a link, called the interference index, is the number of interfering links surrounding it. Two links are said to interfere with each other, if the distance between the mid points of the two links is within the interference range. The interference index of a path is the sum of the interference index values of the constituent links. The destination selects the path with the minimum interference index value and notifies the source through the Route-Reply packet. Simulation results demonstrate that MIF incurs a significant reduction in the end-to-end delay per data packet vis-à-vis the interference-aware load balancing routing protocol.
