An ad hoc network is a set of wireless mobile hosts which form a provisional network without the help or central administration of an existing infrastructure. An Ad Hoc vehicle network (VANET) utilizes shifting cars as portable network servers are created. Each involved unit becomes a mobile router with a VANET. The technique of networking of VANET is fast and versatile investments of equipment and VANET will not be restricted by set topology. A big number of road based implementation of portable apps ranging from the dissemination of vehicle warning and vibrant path scheduling to the promotion of context and file sharing are anticipated to assist VANET. The primary issues are: routing, broadcasting, service quality (QoS), collision avoidance, traffic optimization, network management, low error tolerance, security. The most important issues are: The design of an effective VANET routing protocol is very difficult; a relatively more stable routings must be established by the routing protocol. A range of road protocols was developed to deal with the problem of routing. Several protocols do not influence the stream of vehicles through the longest track between the origin and the target. VANET routing protocols efficiency is dependent on different parameters, such as mobility model, operating atmosphere, and many more. Fuzzy logic has been used in the protocol planning studies for wireless Ad Hoc networks, given that it is nice to choose the highest secure path from the notion of the fuzzy sets. In the draft job fuse oriented routing protocol the car lifetime, car number of cars travelling along the same lines and the distance between the stubble regarded three significant considerations for track choice are taken into consideration.


In the Vehicular Ad hoc Networks (VANET), performance is the key factor for the development of a standard routing protocol. The general characteristics of VANET are dynamic vehicle network topology and mobility. The choice of a better next forwarding hop vehicle among the available neighboring vehicles will lead better use of the route and also minimize the delays. However, there is a need for an efficient decision making in selecting the route for successful packet delivery. This paper proposes a new hybrid routing protocol called “Fuzzy assisted Location Aided Routing using Cache” (FLAR-C). FLAR-C uses a fuzzy logic technique that helps in better decision making to select the next hop for packet forwarding. Metrics like distance, direction, velocity, density and position of next hop vehicle are placed into the fuzzy logic system. And moreover, the proposed technique uses cache schemes to forward packets to the destinations under the Geocast zone. An experimental study is carried out to prove the performance of the proposed protocol and the simulation results highlights that FLAR-C is more effective in selecting the better forwarding hop for improved performance

Vehicular Ad Hoc Networks (VANETs) is the most growing research area in wireless communication and has been gaining significant attention over recent years due to its role in designing intelligent transportation systems. Wireless multi-hop forwarding in VANETs is challenging since the data has to be relayed as soon as possible through the intermediate vehicles from the source to destination. This paper proposes a modified fuzzy-based greedy routing protocol (MFGR) which is an enhanced version of fuzzy logic-based greedy routing protocol (FLGR). Our proposed protocol applies fuzzy logic for the selection of the next greedy forwarder to forward the data reliably towards the destination. Five parameters, namely distance, direction, speed, position, and trust have been used to evaluate the node’s stability using fuzzy logic. The simulation results demonstrate that the proposed MFGR scheme can achieve the best performance in terms of the highest packet delivery ratio (PDR) and minimizes the average number of hops among all protocols.
