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.

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
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.

DT-GPSR: Delay Tolerant-Greedy Perimeter Stateless Routing Protocol
The Journal of Korean Institute of Communications and Information Sciences, 2016 실제 이동 통신 환경은 불균일한 단말 분포와 이동성으로 인하여 링크 단절이 일어나는 경우가 빈번하다. 이러한 네트워크 환경에서 경로 수립 기반의 MANET 라우팅 프로토콜은 잦은 전송 실패를 야기하여 메시지 전달률을 감소시키고, 경로 재수립을 위한 제어 메시지를 많이 발생시켜 네트워크 효율성을 크게 저하시킨다. 반면 GPSR과 같은 위치 정보 기반 MANET 라우팅 프로토콜은 종단 간 경로 수립 절차 없이 hop-by-hop 라우팅을 수행하여 제어 메시지 발생을 최소화하지만, 중계 노드의 결손으로 인해 보이드(void)가 발생 할 경우 데이터 전달 실패 등 다양한 문제를 유발한다.

An Enhanced GPSR Protocol for Vehicular Ad hoc Networks
2019 11th Computer Science and Electronic Engineering (CEEC), 2019Several routing protocols have been proposed for ad hoc vehicle networks. They affect directly but differently the quality of the transmitted data. In this paper, we introduce a multipath feature to decrease packet loss in greedy perimeter stateless routing protocol (GPSR).

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
