Lightweight VANET Architecture for Efficient Secure Data Transmission using CPABE & IBOOS

Cloud computing is a network access concept that provides simple, on-demand network access to a shared pool of customizable computing resources (such as networks, servers, storage, applications, and services) that can be quickly provided and released with minimal administrative effort or service provider involvement. The idea of having a communication node on-board a vehicle that may make wireless connections with other adjacent communication nodes visible in the radio range is referred to as a Vehicular Adhoc Network (VANET). The main focus of this paper is to design lightweight Vehicular Adhoc Network architecture for efficient secure data transmission. An improved Ciphertext Policy Attribute Based Encryption scheme and Identity Based offline/online Signature scheme are proposed to reduce the computational cost, storage overhead and communication overhead in vehicular ad-hoc network. Finally, concluded that the proposed work yields high performance than the existing work.

Effective Routing in Vehicular Adhoc Network (VANET) using an Bio-inspired Algorithm: Enhanced Deep Reinforcement Learning (EDRL) for Secure Wireless Communication

For improving the performance of city wide-ranging lane networks through the optimized control signal, we proposed a framework in Vehicular Adhoc Network (VANET). Node which reduces the traffic efficiency drastically is identified as critical node, with the help of defined framework. Tripartite graph is used for identifying critical node through vehicle trajectory in the over-all viewpoint. Enhanced Deep Reinforcement Learning (EDRL) method is introduced to control the traffic signal and gives appropriate decision for routing the data from Road Side Unit (RSU) to intermediate or destination node. Various experiments were done with proposed model and the result shows considerable efficiency in delay and travelling time of the node in VANET.

An Implementation and Modification of Routing Protocol Against Vehicular Adhoc Network

Today the sector is transferring toward wi-fi system. Wireless networks are gaining reputation to its height today, because the customers need wi-fi connectivity regardless of their geographic position. Vehicular advert-hoc networks (VANETs) are taken into consideration to be the unique software of infrastructure-much less wi-fi Mobile advert-hoc community (MANET). In those networks, motors are used as nodes. The thesis works is primarily based totally on assessment among Ad hoc on call for Distance Vector routing protocol (AODV) and Modified ADHOC call for distance vector routing (MAODV) in VANET on the idea of electricity, packet shipping ratio, throughout, overhead and give up to give up delay. Researchers are constantly publishing paperson overall performance paintings on VANET for this reason we labored at the issue. The gear which we used for the paintings of overall performance are NETWORK SIMULATOR (NS2).

Enhancement of Routing Protocols for Mobile Adhoc Network

The primaryaim of an ad-hoc network routing protocol is accurate and efficient route creation between node pairs so that messages may be delivered promptly. Route creation need to be done with reduced overhead and bandwidth. This paper presents a scheme to reduce bandwidth and power by the hibernation of nodes for a limited time. The effect of our proposal is then studied by simulation under various conditions and the analysis of the simulation results is done to comprehend the working of our protocol in various areas and how it fares in an application specific scenario.

VANET routing Protocols :Implementation and Analysis Using NS3 and SUMO

The emerging new form of mobile adhoc network VANETNetwork is exemplifiedby fast and drastic changes in topology over a shorter period of time. These two features have a significant impact on the efficiency ofrouting protocols used in these networks. The evaluation of various VANET routing protocols provides great feedback on the efficiency of the network. The efficacy of AODV, OLSR, DSDV and DSR protocols is evaluated in this analysis, within the VANET intersection. The movement patterns of vehicles are generated with SUMO and the simulator is NS3.Considering VANET's high velocity, frequent disassociation and highly evolving topology, the major challenge is to create a routing protocol that is more appropriate to efficiently routing packet to their end destination. System of measurementsuch as power consumption, packet distribution factor, average performance as well as maximum end-to-end delay being calculated

Resource-Aware Topology Adaptation in P2P Overlay Adhoc Network

With the emergence of wireless devices, service delivery for mobile as hoc networks (MANET) has started to attract a lot of attention recently. We believe that overlay networks, particularly peer-to-peer (P2P) systems, is a good abstraction for application design and deployment over ad hoc networks. The principal benefit of this approach is that application states are only maintained by the nodes involved in the application execution and all other nodes only perform networking related functions. We propose a P2P system for MANET, RAON, which performs query forwarding and overlay topology adaptation based on link instability and power constraints. We evaluated and compared the performance of RAON with an existing P2P system, Gia. Our simulation results show that RAON improves the success rate and delay of query search as compared to Gia. It, however, achieves this at the expense of higher energy consumption.
