Green Smart Sensing for Geo Communication in VANETs

ABSTRACT

In the overall effort of converting CO2 emissions from tree especially in urban vehicular communications can play an important role. Vehicular communication is comes under VANET which is used to allow the vehicles to communicate with neighbouring automobiles and Road Side Units(RSU). In VANET , vehicles can broadcasts the packet of information like road condition, weather condition and accident information, etc. In this paper we propose a real time system based on dedicated short-range communication (DSRC) between the tree and vehicles capabilities in order to reroute vehicles to the most ecological route.

In this process CO2 from tree converts it into electrical energy for data transmission between the vehicles, regard V2V is a vehicular ad hoc network designed for automobiles to talk to each other automatically, using a wireless ad hoc network. This process is experimented using NS-2 simulator which is a simulator targeted at networking research.

VANET is a vehicular communication network used to exchange packets of information between the moving vehicles with the help of roadside units (RSU) . The impact that is made by network communication on green environment cannot be hidden. The exchange of information capacity of VANETs can be employed to issue the Intelligent Transportation System (ITS) services for users. ITS used to improving safety and driving applications, minimizing the accident count, used to minimize transportation systems, decreasing fuel usage and CO2 emissions, and issuing Internet access for automobiles.

The data transmission done by the networks increases by a percentage of 10 every 5 years.

Green communications and green technologies have been implemented as solutions to tackle the growing cost of telecommunication energy consumption and its environmental issues. As it provides scalability and robustness against frequent topology change, Geographical routing was considered a promising routing approach for dynamic environments. In geographical routing the forwarding of packets are done based on the geographic positions of vehicles instead of address. Dedicated short range communication introduced between tree and vehicles to reroute the vehicles, DSRC is a wireless communication technology designed to allow vehicles in the intelligent transportation system to communicate with other vehicles or infrastructure(RSU) technology. Here we convert the CO2 emitted from the trees nearby the roads into energy ,which acts as an input for the base communications using this the vehicles communicate with the road side unit and transfers the information packets .Every vehicle act as a node in VANET ,where in case of any emergency the information is passed from one node to every other node connected with the RSU around a particular region.

PROCESSING OF MODULES

The processing of modules consists of six phases which are abstracted below

INITIALIZATION PHASE

In this process the vehicle movement with data transmission has to be implemented. In the initialization phase, the root vehicle chooses an additive group of point G1 with order q, and P is a generator of G1. Notice that the system parameters are preinstalled into the TPD of all vehicles and RSU. Each vehicle act as a node, which transfers information with each other if any emergency is occurred such as an accident, road condition, weather condition, etc…

CO2 to ENERGY GENERATION

By using the tree located near the roads we generate CO2 and convert it into electric signal which acts as energy for passing the information packets between nodes. After the conversion electric signal it has been sent to vehicles for data transmission. The process of data transmission can be occurred between vehicles for mobility using the part action of road side unit, which controls and monitors the exchanging of information between the nodes of transmission. The exchanging of information may be in the type of signals like vibrating of seats, visual display, any unusual tone of sounds or combination of these indicators. The first node receives these signal and transfer the signal to next node and so on through wireless communication. The packet of information passing is achieved by 802.11 wireless communication.

VECHICLE REGISTRATION PHASE

When a new vehicle user Vi wants to join a VANET, he/she needs to register first. After registration, the Vehicle of Vi must be initialized. The procedure of vehicle registration is described as follows.

1. A new vehicle user Vi submits the real identity through a secure channel.
2. Upon receipt of the message, the first checks whether it exists in the vehicle information table. After analysing the vehicle registration the RSU provide the authority for using the mechanism as an authorised user .The RSU provides an individual interaction identity to every vehicle act as a node after analysing the real identity provided by the user. The nodes exchange information between the every other nodes after the proper authentication of road side unit.

RSU REGISTRATION PHASE

When an RSU Rj is deployed, Rj is required to register. The procedure of sensor node registration is described as follows.

1. A new RSU selects the identity and transmits it to vehicle via a secure channel. The channel transmission is done by the TCP/FTP protocol.
2. After receiving the identity, vehicle first checks whether it exists in the RSU information table. If not the vehicle acknowledges and resends the packet and requests for an another identity. Once the identity is accepted by the user, the vehicle received starts to connect with the road side unit and transfers the packet information to the neighbour vehicles in the particular region.AUTHENTICATION AND MEMBER SECRETS GENERTE PHASE

When a vehicle enters into the communication range of Rj , it requests to join the subgroup of Rj .If Vi has joined this subgroup, and the authorized period is not expired, it does nothing. Subgroup is nothing but the collection of vehicles that act as different nodes which comes under a connection region that are monitored by the RSU. Once the vehicle leaves the communication range it automatically connects with another RSU which performs the exchanging mechanisms under that particular range. The information about the user of this process can protected from illegal access. The confidentiality of the user information should be maintained. Authentication is used to verify valid user based on their identity submitted before for the registration process. This secures the information and used to avoid invalid information that is passed on the channels. Unauthorised user cannot access those information passed by the RSU , it is mandatory to register the vehicle for the communication transmission through the rules and registration based on the identity provided.

RELATED THEOR

VANET

A spontaneous creation of a wireless network for vehicle-to-vehicle(V2V) data exchange to the domain of vehicles is VANET. It is a mobile communication ad hoc and application, where the information relayed between the automobiles. To provide road safety the vehicle-to-vehicle and vehicle to road side communication co-exists. It is key part of Intelligent Transportation System(ITS),which is an advanced application that aims to provide innovative Services relating to traffic management, and road side unit. In early days VANETs were seen as a one to one application of MANET. But after some application programs, with more generic terms it was implemented as one to many ,it always focus remains on the spontaneous aspects of networking more than RSU.

GEOGRAPHICAL ROUTING

Geographical Routing is routing that depends on geographical position information. It works on wireless networks, it depends on the geographical location other than the Packet address. It requires on destination and sender nodes. The single path, multi path and flooding based strategies are the approaches. It is also called NFP and compare routing . Using Geographical routing the routing of the architectural networking of a metropolitan scale are done . It is Portion based Routing and invalid information or mistakenly sending packets are avoided and invalid address issues are overcome. Geographical Face Routing is the position based protocol.

CO2 CONVERSION

The production of energy is through the emission of CO2. To convert CO2 into more reactive molecule, It is synthesized by the variety of products. The O2- assisted Al/Co2 electro-chemical cell, which is an System for CO2 captured conversion and electric power generation is used to convert into energy. It increases the suitable ,sustainable environment for human and decreases the pollution in a rate in useful way.

DEDICATED SHORT RANGE COMMUNICATION

An medium wireless range designed specifically for the automotive use which permits high data transmission based on safety applications. It is mostly preferred to connect in cars, it transfers high capacity packets in critical data, used for vehicle related safety and mobility systems. It assists the user with driver assistance and with autonomous driving feature to reduce traffic accidents and fatalities it is very useful for v2x communications as it supports very low latency, secure transmissions, fast networks acquisition. Highly robust in adverse weather condition.

CONCLUSION

CO2 to energy transformation routing is a prominent research field in vehicular ad hoc networks. In particular, routing aims at decreasing the energy usage while transferring packets of information from source node to destination node,. Since, energy conversion routing modify well to the dynamic network environment, combination of AODV routing and CO2 to energy routing methods results in routing information efficiently with the minimized amount of energy consumption. In conclusion, extra research effort is needed to design more energy-efficient dedicated short-range communication (DSRC) routing protocols and introduce more accurate approaches for protocols evaluation.
