Connecting Wireless Sensor Networks Using Gateway Nodes
Sjoerd Langkemper, Vrije Universiteit Amsterdam, The Netherlands, 2007.
Wireless sensor networks consist of many radio-equipped nodes which are limited in resources and power. Nodes that can be reached by radio, possibly through multiple hops, form one network. This master thesis presents a way to connect two or more networks together, using gateway nodes that have a wired connection with each other. This way, it appears to the nodes as if the two networks have a radio connection. We also show through simulations that the system we propose gives a good connection between the networks, but breaks the working of synchronous protocols.
