One of the main constraint in front of Vehicular Ad hoc Networks (VANETs) is delivering the data in efficient time. This paper provides an improved Greedy Perimeter Stateless Routing protocol (GPSR) to enhance the video quality transmission over VANETs. We propose to adapt the mechanism of GPSR through a modification on greedy process. This latter uses

GPSR Routing Protocol in Urban Environment
Applied Mechanics and Materials, 2011The research on Communication based on Ad hoc networks between vehicles is highly concerned about in many countries. However, Vehicular Ad hoc Networks (VANETs) is in the environment in which traditional methods have certain limitations. In this paper, vehicular network scenarios and the probability of penetration model are given.

An Improved GPSR Routing Strategy in VANET
2012 8th International Conference on Wireless Communications, Networking and Mobile Computing, 2012As a special type of mobile Ad hoc network, VANET has increasingly become an attractive technology in terms of safety driving and comfortable network services provided to vehicular users. However, high mobility of vehicular nodes in VANET makes network topology changing frequently, and this makes route unavailability and causes high data packet loss ...

Improved GPSR-SD Routing Protocol for VANET
Journal of Highway and Transportation Research and Development (English Edition), 2017Routing is the key technology of a vehicular ad hoc network (VANET). On the basis of the high mobility of nodes and the vast frequent changes of the network topology of ad hoc networks, this study proposed an improved greedy perimeter stateless routing with speed-density direction (GPSR-SD) routing protocol, which is based on the GPSR protocol.

An Adaptive GPSR Routing Protocol for VANETs
2018 15th International Symposium on Wireless Communication Systems (ISWCS), 2018The fast topology change and high-speed mobility of vehicles, as well as the limited radio range, usually lead to wrong packet forwarding decisions in highly dynamic Vehicular Ad Hoc Network (VANET). This type of environment makes data routing very challenging.

Research on One Kind of Improved GPSR Algorithm
2012 International Conference on Computer Science and Electronics Engineering, 2012In GPSR algorithm's perimeter forwarding mode, the right hand-rule is able to ensure the GPSR protocol can go out of the "hole", but it makes the choice have arbitrariness to some extent, which often lead to find larger routing hops. An improved GPSR routing algorithm using double-hands rule is proposed to resolve the "hole" problem of GPSR in wireless

Improved GPSR routing algorithm and its performance analysis
2010 IEEE International Conference on Software Engineering and Service Sciences, 2010An improved GPSR routing algorithm is proposed to resolve the energy sensing problem of GPSR. In order to balance the energy-consumption of nodes, improved GPSR routing algorithm uses node's remnant energy as one of the key factors to decide next-hop.

e-GPSR for LDR-L/T UWB sensor networks
2008 Third International Conference on Communications and Networking in China, 2008Routing performance is evaluated for a network of low data rate location/tracking UWB sensors that implement the energy-aware greedy perimeter stateless routing (e-GPSR). Sensors have both location/tracking and communication capabilities, that allow the use of a geographic reactive multi-hop routing protocol, like the e-GPSR.

Trusted GPSR protocol without reputation faking in VANET
The Journal of China Universities of Posts and Telecommunications, 2015Abstract In vehicular ad hoc network (VANET), misbehaviors of internal nodes, such as discarding packets, may lead to a rapid decline in packet delivery ratio. To solve this problem, an improvement of greedy perimeter stateless routing (GPSR) protocol is presented. In the new protocol, trustworthiness is considered in the route selection process. The

An Evolving GPSR Protocol in Urban Roundabout Scenario
Applied Mechanics and Materials, 2014According to the research of VANET routing protocol, an improved protocol SN-GPSR has been proposed. It is based on the sensitive nodes. The nodes select routing through a special position and steady speed under GPSR protocol. In a crossroads scenario, we designed a vehicular mobility model and simulated it using NS-2.
