Hoc Networks

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.

Hoc Networks

Vehicular Ad Hoc Networks represent a specialized application of Mobile Ad Hoc Networks. Here the mobile nodes move in lanes and their mobility can be modeled based on realistic traffic scenarios. To meet the above challenge the goal of defining the mobility model for vehicular ad hoc network along with a realistic traffic pattern is an important research area. Vehicular mobility is characterized by acceleration, deceleration, possibility of different lanes and intelligent driving patterns. Also a modeling of traffic is necessary to evaluate a vehicular ad hoc network in a highway environment. The traffic model has to take into account the driver behavior in order to take decisions of when to overtake, change lanes, accelerate and decelerate. To overcome the limitation of traditional mobility models and mimic traffic models, many traffic model based simulators like CORSIM, PARAMICS and MOVE have been proposed. In this chapter we provide taxonomy of mobility models and analyze their implications. To study the impact of mobility model on routing protocol for vehicular motion of nodes we analyze the performance of mobility models with suitable metrics and study their correlation with routing protocol. We also discuss the fundamentals of traffic engineering and provide an insight into traffic dynamics with the Intelligent Driver Model along with its lane changing behavior.

According to characteristics that the vehicles move fast and topology changes quickly in Vehicular Ad hoc Networks (VANETs), a novel routing protocol GMGP based on the location is proposed for VANETs. Predicting the changes of the neighboring nodes positions and using greedy forwarding mechanism forward packet, and using a movement perimeter forwarding algorithm to select the next reliable hop node on the basis of direction and velocity of the mobile nodes when the greedy forwarding fails, it improves the reliability of routing. When a more realistic vehicles mobility model is applied to the NS-2 simulation platform, the simulation indicates that the improved routing protocol has better performance than the GPSR routing protocol.

Fuzzy Logic Technique

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
