Performance Evaluation for Heterogeneous D2D communications with Data Dissemination Based Routing in Urban VANETs Environment

Urban based vehicular communication had an immersive development in recent years as well is occupies maximum of the attention of the Intelligent Transportation Systems (ITS). Due to the characteristics of vehicles, it underwent certain drawbacks like high-speed vehicle, unpredictable mobility and so on. To overcome this, it becomes indispensable to reduce the networks high power utility, delay and overhead. For that purpose, in this paper heterogeneous D2D communications with data dissemination-based routing (HDC-LSAV) is proposed. In heterogeneous communication the cluster-based network is constructed where the vehicles are divided into certain groups and it gets controlled by its cluster head (CH) as the results of cluster-based communication the power utilization of the vehicles are reduced. To transmit the data in an optimal way a data dissemination-based routing is used which helps to reduce the delay at each instant of data transmission. The experimental demonstration of the HDC-LSAV is performed in NS2 with SUMO and the parameters which are used for the performance analysis are taking throughput, overhead, delay, and packet delivery ratio and as well the results are compared with the earlier methods namely ICCA-MHV and MDEC-LTV. From the outcome it is proven that the HDC-LSAV achieved 18% higher delivery ratio and 100 kbps higher throughput.
