Araçlar arası haberleşme için küme yapısı tasarımı

Recently, vehicular ad hoc networks (VANET) are introduced by the research community. VANET is a special subset of mobile ad hoc networks where nodes are cars and other vehicles; and networking environment consists of streets, roads and highways. The essential technologies fall into two major categories: infrastructure to vehicle (I2V) and vehicle to vehicle (V2V) communications.The primary purpose of VANETs is the deployment of safety-related applications divided into three main groups: driver assistance, information and emergency warning services. Additionally, various commercial applications may be deployed as well by exploiting the underlining technology.Cluster formation for IVC (CF-IVC) presented in this thesis intends to control medium access of the nodes and form a virtual backbone for routing by dividing the network into smaller manageable groups. It offers all the benefits of clustering such as spatial reuse of resources and a scalable network since overall network appears smaller and more stable to each mobile terminal. CF-IVC also introduces a new mechanism to handle mobility and the allocation of reusable orthogonal codes to each node provides a contention-free medium access control.The proposed protocol was evaluated by a simulation scenario that runs on top of the OMNeT++ platform and the obtained results show that CF-IVC reaches its intended goals at a reasonable cost.
