Proposal of a hybrid DSRC/LTE communication framework for smart cities

| Summary: | As it is known, the demand for cellular network traffic has grown exponentially, so one of the solutions to meet the traffic demand has been to reduce the cell coverage radius. Therefore, in order to cover a large area such as a city for instance, it is necessary to deploy a large number of cellular antennas. This research presents an alternative proposal to the cellular coverage problem through the use of a hybrid or heterogeneous network formed by the Long Term Evolution (LTE) cellular network and the network based on the IEEE 802.11p standard known as DSRC. Then, the coverage radius of the LTE network can be "extended" by multiple re-transmissions through the Dedicated Short Range Communications (DSRC) network until when it is possible to use the LTE network and communicate with the base radio or evolved Node B (eNB). In this thesis is introduced an heterogeneous communication system for vehicular applications within the scope of smart cities. The scenario presented consists of a server located in the area of L'Eixample in the city of Barcelona, which is directly connected to an eNB, so that vehicles circulating in that area can communicate with the server regardless of whether or not they are within the coverage area of the eNB, thanks to the implementation of our proposal of an heterogeneous protocol named Het-net. We have carried out a performance evaluation using a realistic OMNeT/SimuLTE simulation platform that shows the benefits of our proposal in terms of average packet delay, packet delivery ratio and hop count. |
