Link Failure Tolerant GPSR Protocol [PDF]

International Journal of Networked and Distributed Computing (IJNDC), 2021
Link failure cause packet loss, increased delays, disconnection from the network or even the shutdown of the inter-vehicle communication system vehicle-to-vehicle. Routing protocols suffer from this situation due to the lack of fault tolerance mechanisms

GPSR: Gradient-Prior-Based Network for Image Super-Resolution [PDF]

Applied Sciences, 2023
Recent deep learning has shown great potential in super-resolution (SR) tasks. However, most deep learning-based SR networks are optimized via pixel-level loss (i.e., L1, L2, and MSE), which forces the networks to output the average of all possible ...

Weight-Based PA-GPSR Protocol Improvement Method in VANET [PDF]

Sensors, 2023
Vehicle Ad-hoc network (VANET) can provide technical support and solutions for the construction of intelligent and efficient transportation systems, and the routing protocol directly affects the efficiency of VANET. The rapid movement of nodes and uneven

Traj-Q-GPSR: A Trajectory-Informed and Q-Learning Enhanced GPSR Protocol for Mission-Oriented FANETs [PDF]

Drones
Routing in flying ad hoc networks (FANETs) is hindered by high mobility, trajectory-induced topology dynamics, and energy constraints. Conventional topology-based or position-based protocols often fail due to stale link information and limited neighbor ...

WA-GPSR: Weight-Aware GPSR-Based Routing Protocol for VANET

International Journal of Interactive Mobile Technologies (iJIM), 2021
The extremely fast topology has created new requirements for the geographic routing protocol, which has been the most efficient solution for Vehicular Ad-hoc Networks (VANETs). The frequent disconnection of links makes the choice of the next routing node extremely difficult. Hence, an efficient routing algorithm needs to deliver the appropriate path to

Available bandwidth estimation in GPSR for VANETs

Proceedings of the third ACM international symposium on Design and analysis of intelligent vehicular networks and applications, 2013
This paper proposes an adaptation of the collision probability used in the measure of the available bandwidth designed for Mobile Ad hoc Networks (MANETs) and which is described in ABE [12]. Instead, we propose a new ABE+ that includes a new function to estimate the probability of losses.

A GPSR Enhancement Mechanism for Routing in VANETs [PDF]

, 2015
Vehicular Ad Hoc Networks (VANETs) are considered as a special case of mobile Ad Hoc Networks (MANETs) and are recently gaining a great attention from the research community. The need for improved road safety, traffic efficiency and direct communication along with the great complexity in routing, makes VANETs a highly challenging field.
