Peer-to-Peer Protocol for Allocated Resources in Vehicular Cloud Based on V2V Communication

摘要

Intelligent transport systems (ITS) may take advantage of the mobile cloud, in other words, the vehicular cloud may provide a lot of services for assisting traffic, accident prevention, and content delivery, among others. However, search and allocation resources in the vehicular cloud has become challenging, due to vehicular network characteristics, and also to the necessity of attempting the QoS requirements of service independently of the external condition. Thus, one of the biggest obstacles in these environments is to allocate and share resources available in vehicles without the need for external infrastructure. With this challenge in mind, we propose a new protocol designed to facilitate resource sharing via mobile cloud in the vehicular network. Simulation results show that the proposed approach introduces a short search time of approximately 0.7 (ms) to query resources in one hop, and about 1.0 (ms) to seek resources in more than one hop. Furthermore, the proposed protocol enables a high availability of resources, about 95%.
