A ZONE TIME BASED VEHICULAR AD-HOC CLOUD NETWORK SERVICES MANAGEMENT SYSTEM

Abstract

Vehicular Ad-hoc Networks (VANET) is a network infrastructure that provides the communications among vehicles and have many Characteristics including reducing congestion, minimizing accidents, reducing fuel consumptions etc. The concept of cloud computing basically relies on using of the idle vehicles resources and provision it for other vehicles either for free, or a user only pay for services used (e.g. memory, processing time and bandwidth etc.). Exploiting the added benefits of Cloud Computing and merging it with VANET is an advance step that requires a special designs and solutions to accommodate VANETs characteristics with the cloud concept requirements. The main problem for vehicular cloud networks is high mobility and difficult predictability in urban area, making it difficult to implement in connection and data processing, because continuous interruptions in communication lead to loss data. Therefore, in this paper, we proposed a system to manage some vehicular cloud network services to ensure all these services completed without dropped or disconnected during execution time. We adopt the concept of dynamic vehicles, which will satisfy the needs of the users. Dynamic vehicle is evaluated with respect to spending time within the zone, this time is calculated in several ways and in most cases the best vehicles participating in the service are selected depending on zone time. The proposed system is compared with the normal system. For accurate comparison, two important metrics are selected, i.e. throughput and packet delivery ratio to evaluate the two systems. The results proved that our system is more reliable and efficient than the normal system in different scenarios.
