Figure 4From: Enabling direct connectivity between heterogeneous objects in the internet of things through a network-service-oriented architectureThe coverage of an existing legacy network is expanded by installing an additional next-generation backbone. (i) Using existing technology, all communication must pass through a translation gateway, resulting in suboptimal use of the network. (ii) A next-generation IDRA network can converge with existing networks and use direct communication paths, thus prolonging the operational lifetime of legacy networks.Back to article page
