A new solution based on optimal link-state routing for named data MANET

Abstract

NDN is an important instance of Information-Centric Networking. When integrating NDN into MANET, exploring new routing is a necessary task for this research area. The LSAs flooding is a common method to obtain network topology during route establishment. However, the LSAs flooding often results in a broadcast storm in high-density MANET. Using the MPR set proposed in the OLSR can effectively reduce the number of LSAs in the process of route establishment and can further solve the broadcast storm. In this paper, an enhanced neighbor discovery protocol firstly is designed to establish a MPR set. The new protocol can effectively avoid the problem incurred by unidirectional links that impact the network performance in a wireless environment. And then a new and proactive routing NOLSR based on OLSR for NDN-MANET is proposed to support NDN in MANET. And another important work is that NOLSR is implemented on top of NDN Forwarding Daemon NFD. Finally, we make a comparative analysis between NOLSR and the two most relative schemes such as traditional LSA-flooding and the scheme [1] by emulation experiments in the NDN emulator mini-NDN.
