Heterogeneous Network Handover Techniques for Vehicular Communication: Methods and Techniques

Heterogeneous wireless networks include wireless local area networks, dedicated short-range communication (DSRC), Device-to-Device (D2D) communications, and cellular networks. It provides the wireless coverage area by using several combinations of macro-cells, picocells, and femtocells. For heterogeneous wireless networks, it is necessary to provide robust mobility to users so that the process of handover among networks can occur without any disruption. In VANET handover is required because vehicles move out very frequently from one to another network region. The handover process is nothing but measurements of signals from the neighbouring base stations (BSs), as well as it depends upon the frequency and time selectivity of the radio propagation network. At high speed, there is a huge chance of failure happened in the handover process. Mobility management techniques are required to im- prove mobility in the heterogeneous network. In this paper, we describe data package handover characteristics in Het-Net. Also, discuss different handover types and their behaviors in different conditions.
