Zusammenfassung: | Vehicular ad hoc networks is a modern technology that holds an important
aspect in the transportation domain due to its abilities to increase traffic
efficiency and safety. It is a another variant of Mobile ad-hoc networks that
provides Vehicles to Vehicles (V2V), Rode-side Unit to Road-side Unit(R2R) and
Vehicles to road-side Unit (V2R) communication.VANET is a multidimensional
network in which the vehicles ceaselessly alter their locations. Connected
vehicles broadcast sensitive information which must be communicated with the
neighbors in a safe and established environment. VANET may also contain
dishonest nodes such as man in -the-middle attackers that aim to distribute and
share malicious content with the vehicles, thus contaminating the network with
secure information. In this situation implementing a trust among connected
vehicles can raise security as every participating vehicle will create and
propagate authentic, accurate,and trusted content within the network.In this
paper we used a trust model to determine the trust level and eliminate the
malicious nodes.We created a simulation for calculating the trust level and
eliminating the malicious node in the wireless ad hoc networks using ns2
simulator and network animator(nam).The simulation results showed a better
bandwidth in communication between the nodes after the trust level is updated |
