Empirical Data Analysis in Urban VANET Using Exponential Decay of Inter Contact Time
Main Article Content
Abstract
VANET is a technology that uses moving vehicles as nodes in a network to create a mobile network .It is used to improve safety, security and efficiency of transportation systems. Inter-contact Time between moving vehicle is a key metrics in VANET , and for forwarding data and end to end delay. Inter-contact Time denotes the time elapsed between two successive contacts of the same two vehicles. In order to trace data on the frequencies and duration of transfers between vehicles three models were upgraded. No method or mobility models are proposed to decrease the end to end delay while transferring process, due to interference and signal loss of wireless links. The proposed system uses a Time Variant Random Way Point Mobility Model which minimizes the inter-contact time distribution, data transfer rate and reduces the delay. It improves the texture of Common traffic influxes and Common traffic converges.
