Design and Implementation of NOLSR for NDN-MANET Routing

Named Data Network (NDN) is an important instance of future internet architec-tures. NDN-MANET routing is a hot research area. Link State Advertisements (LSAs) flood-ing is a common method to obtain network to-pology during routes establishment. However, LSAs flooding often causes a broadcast storm in high-density MANET. Using a MultiPoint Relay (MPR) set proposed in the Optimized Link State Routing protocol (OLSR) can ef-fectively reduce the number of LSAs in the process of route establishment. So, this solu-tion can solve the broadcast storm. Based on OLSR, we design and implement a novel rout-ing Named-data Optimized Link State Rout-ing protocol (NOLSR) for NDN-MANET. In NOLSR, a new neighbor discovery protocol to establish the MPR set is proposed. Only nodes in the MPR set will forward LSAs so that other nodes can obtain a network topolo-gy and further establish the routing table. The neighbor discovery protocol can also avoid the problem of unidirectional links which impacts the performance of a network. Finally, we make a comparative analysis between classic flooding and NOLSR by simulation experi-ment in an NDN emulator mini-NDN.
