A cluster-based locality-aware mobile peer-to-peer architecture

Mobile peer-to-peer networks combining a mobile ad hoc network underlay with a peer-to-peer overlay offer a flexible means for providing communication services in absence of a communication infrastructure. However, mobile peer-to-peer networks inherit several challenges from the underlying architectures as, e.g., strongly limited resources and a highly dynamic topology. Due to this, the overlay has to be adapted in order to provide reliable services. We introduce a mobile peer-to-peer architecture that harnesses the location awareness and clusters nodes by their location. By means of simulation, we show that the overhead generated by lookup requests, bootstrapping, and the updating mechanism of the routing tables can be strongly reduced.
