Closed User Group Automotive Communication Network Based on Addressing at Physical Layer

Abstract

Intelligent Vehicle communication is the keyword for the emerging vehicular technologies such as group cooperative driving, real time Engine Operating parameters (EOP) monitoring, collision warning, geo location based mobility applications, and classical voice and data conveyance. The technologies require extensive interaction between the peers which mostly use the framework of the state of the art cellular or radio trunking networks. This may vitiate the network performance due to the surge in mobility management messages originated by the devices plugged in the vehicles. The performance may be severely impacted due to the unique characteristics of vehicular networks e.g., high mobility. Due to the high proliferation of these Machine to Machine (M2M) and Machine to Application (M2A) devices in near future, the cell sizes will shrink, resulting in more signalling messages in the network. Considering classical voice communication services for typical car fleet implementations, the radio trunking networks have capacity constrains due to inability of frequency reuse and absence of mobility management techniques. The alternative is to seek out an access technology considering the fact that a more intelligent physical layer can be employed directly for addressing and mobility management. In this paper the authors address a Closed User Group network implementation for Vehicle to Vehicle/central office communication which can actuate voice and data communication without incorporating any application layer.

Enabling Cellular Device to Device Data Exchange on WISDOM 5G by Actuating Cooperative Communication Based on SMNAT

“…One of the suitable candidates seems to be SMNAT (Sanyal, R., Cianca, E. and Prasad,R.,2012a) which deploys the addressing and mobility management methods at physical layer. In (Sanyal, R., Cianca, E. and Prasad,R.,2012d), we saw how direct communication between two vehicles separated by any distance but within the network coverage area can be achieved by using this technology. But this had to be restricted to a closed user group network.…”
