NeTS-FIND: A Geometric Stack for Location-Aware Networking -- Project Summary

By n.n.


As the Internet begins to encompass a larger and more mobile set of devices, including our cars, portable phones, and sensing nodes, a major challenge lies in the integration of location information into the network architecture. Two trends in particular, increasing mobility of nodes and increasing density of network nodes, have led to discussions about the role of location at the network layer. First, mobile IP offers a network layer handoff to enable seamless communications while a node moves between different IP (sub-)networks. Second, geographic routing approaches are widely hailed as a solution to manage the complexity of routing tables, especially in large wireless networks. These services require in-network support for efficient deployment. While these mechanisms have first been proposed about a decade ago, they have so far shared the fate of many other network layer improvements such as multicast, IPv6 addressing, etc. This lack of adoption has raised questions about the viability of evolving the current Internet architecture at the IP layer, and motivates this research for more groundbreaking architectural designs that are free of legacy IP constraints. Apart from network optimizations at the IP layer, the integration of location information will also support a set of novel applications. First, the internal network bookkeeping services for mobile communications can be extended to allow location tracking and location finding of large numbers of objects. This service will be useful for monitoring automotive traffic densities or implementing a lost-object-search function. Second, the availability of location-informatio
