Abstract

Today’s communication is based on Internet Protocol (IP), where IP packets are routed from source to destination hosts via one or more intermediate nodes. The location based routing can be used to route flows for location based services, but cannot be adapted with the current IP networks. Obtaining geospatial location using IP address is not a direct relation. The large volume of traffic flow in Internet obstructs the routing of data flows using geospatial information. The IP header is rigidly structured and provides no space for addition of extra information. The augmentation of geospatial information in IP packet can accomplished using Software Defined Networking (SDN). SDN allows the facility to control network flows by separation of data plane and control plane in the network. The actions associated with the centralized controller paves ways for modification of IP packet. Thus the geotags can be added to the IP header during encapsulation at the SDN controller and encapsulation at the destination. The satellite data can be disseminated o n geotags based routing which provides improved quality of service. Further new application can be built using enrichment of packets using geotags including geofencing, network security related applications. Theoretical results are presented to assess the benefits of proposed geotags based routing and its performance is compared to the traditional dissemination of data flows.
