Aodv Routing Protocol

Vehicular ad hoc networks (VANETs) are upcoming prominent technology in the field of communication with vehicles. It is a combination of mobile and sensor network features. The random change in position of vehicles in VANET made the system more vulnerable to attacks. The most important attack in VANETs to be considered is Black hole attack which increases the chances for packet loss and in turn to accidents. There is a necessity to develop the techniques to detect Black hole attacks and reduce number of accidents. In this paper, a technique called “Detection of Black hole in VANET using AODV (DBVANETuAODV)” is proposed to find and prevent Black hole attack and thereby reducing occurrence of accidents. The proposed solution is implemented using AODV Routing protocol in VANET.The experiments are conducted with SUMO and NS2 simulators to depict network environment in an inexpensive way. The proposed method “DBVANETuAODV” is compared with AODV with black hole and the result shows the proposed method provides a significant improvement.

Aodv Routing Protocol

Mobile Ad hoc Network (MANET) has attracted lots of research efforts these years, mainly due to its appealing applications in no infrastructure situations such as battle fields and disaster recovery operations [1]. In this paper, we explore wireless Ad Hoc network focusing on its Routing Protocol AODV, we in depth analyze its operation principles and the problems exist in AODV routing protocol. AODV routing protocol is vulnerable, it is always exposed to many attacks, such as DoS, black hole, etc. [2] Through exhaustive researching the behaviors of black hole attack in NS2 simulation platform, and we finally propose a new routing security strategy to defense the black hole attack in AODV. Simulation results show that the strategy we proposed can not only effectively defense the black hole nodes, but also has better routing performance for moderate or small scale Ad Hoc Networks.

Aodv Routing Protocol

Vehicular ad hoc networks is an emerging area for researchers to provide intelligent transportation system to the society. It is due to the wide area of applications of VANETs interest is developed among the people from different countries to be a part of it. Therefore many projects had been started and also presently working to implement VANETs in real world scenario. The main challenge in its implementation is to provide a secure mechanism against the various attacks and threats that have the capability to bring the network performance significantly down. In this paper to overcome different types of authentication based attacks in VANETs an ECDSA based secure routing protocol SE-AODV is proposed with security features incorporated in already existing AODV routing protocol. The performance of SE-AODV is evaluated and compared with original AODV and AODV with black hole attack (BH-AODV). The SE-AODV shows better performance with the parameters used for comparison with the variation in vehicle density, speed of vehicles and simulation time.

Aodv Routing Protocol

Workers or labors who are working in construction sites are prone to severe risks such as death, injuries happened due to accidents, falls and stuck in between objects. Internet of things (IoT) based sensors can be utilized to monitor the behavior of workers when they are in danger zones/areas. To safeguard site workers, supervisors or site managers should monitor and alert them when they are in danger. Data will be routed from site worker to supervisor, during this routing process data is subjected to routing attacks such as black hole attack and so on, due to wireless transmission. This article addresses the problem of black hole attack that happens during the wireless transmission between nodes and the base station (BS) of IoT-based civil construction. The proposed solution Collaborative Black Hole Attack – Ad Hoc On-Demand Distance Vector routing protocol (CBHA-AODV) prevents the collaborative black hole attack by 87.72%.
