“…In addition, GPSR heavily depends on the location service providers prone to localization errors caused by obstacles such as large buildings, mountains, weather conditions, etc., for radio propagation. Local maxima and frequent network partition caused by distance‐based greedy forwarding deteriorate its performance significantly 31 . However, GPSR does not consider the node's energy, speed gap, the direction of the neighbor, and the connection's reliability while making forwarding decisions 32 .…”

Flying Ad‐hoc Networks (FANETs) has recently gained significant exposure for their emerging military, civil, and commercial applications. In FANETs, all Unmanned Aerial Vehicles (UAVs) can communicate within a restricted wireless communication range without fixed infrastructure. However, the highly dynamic nature of UAVs imposes a significant issue in FANET's communications. Therefore, designing an effective routing strategy is always necessary for sustaining appropriate network performance in FANETs. This paper is interested in modifying Greedy Perimeter Stateless Routing (GPSR) protocol named Utility Function based Greedy Perimeter Stateless Routing (UF‐GPSR) protocol for FANETs. The proposed approach optimizes the greedy forwarding strategy by considering multiple vital parameters of UAVs: residual energy ratio, distance degree, movement direction, link risk degree, and speed, respectively. The proposed UF‐GPSR applies the utility function on these parameters to enhance the routing performance by selecting optimal next‐hop within the communication range. The effectiveness of the proposed work is mathematically evaluated and then simulated through the NS‐3.23 simulator. The experimental outcomes verify that the proposed routing approach enhances the packet delivery ratio and throughput while decreasing packet drop ratio and delay compared to the other routing approaches: GPSR and GPSR‐PPU.

In the past decade, a steady increase has been noticed in the number of mobile users and the use of mobile communication. In wireless communication links are stable. Duration of the link is the most important design by which the performance of the mobile Ad Hoc network (MANET) can be determined. In this research article, a derivative metric of graph theory attained from mobility model technique in Ad Hoc network of casually moving object, link duration of probability density function (PDF)been examined by using three mobility models namely random waypoint, random direction, and freeway model. The performance is based on the node speed, transmission range, the density of node, area of simulation, and computational complexity with time. By using Monte Carlo simulations, the reliability and robustness of models have been analyzed. The main advantage of the proposed scheme is implemented is an easy hardware platform because of the concept in mobility models and the easiness of code.

“…The work presented in paper [32] examines the benefits and drawbacks of GPSR and proposes a Greedy Perimeter Stateless Routing protocol based on Weight Gradient (GPSR-WG) that improves link risk degree. Multiple routing criteria, such as direction, distance degree, link risk degree, and normalized speed factor are taken into account by GPSR-WG to improve greedy forwarding for health monitoring applications.…”

Natural disasters like earthquakes and tsunami could destroy the existing infrastructure-based communication system. IoT-based health monitoring is not possible in such scenarios. Therefore, there is a need for other resilient health monitoring frameworks to provide consistent health monitoring without depending on existing communication platforms. Wireless Body Sensor Network (WBSN) based health monitoring utilizing Vehicular Ad-hoc Network (VANET) as a communication medium could be a handy solution for transmitting patients' health information to the nearest ambulance or hospital in emergencies or disaster-prone areas. Casualty rates can be reduced significantly by providing emergency treatment to injured patients within a stipulated time. VANET's health monitoring applications are time-critical; therefore, designing a stable and efficient routing algorithm is a significant research challenge. Over the years, the researchers proposed many routing solutions to minimize the delay for critical applications. This paper proposed a Weighted Geographical Routing (W-GeoR) for VANET's health monitoring applications focusing on next-hop node selection for faster vital signs dissemination to facilitate post-disaster health monitoring in urban traffic environments. The proposed protocol utilized traffic-aware information including traffic mobility, inter-vehicle distances, speed differences, communication link expiration time, channel quality, and proximity factors for optimal next-hop node selection procedure. W-GeoR is tested on a postdisaster scenario created with SUMO-0.32 and NS-3.23 platforms. Simulated results confirm that W-GeoR performs better than the existing state-of-the-art protocols.
