Abstract:
|
To disseminate content with content-based routing (CBR), the routing paths of subscription and publication cannot be determined a prior and have to be computed hop-by-hop, which brings in scalability and robustness challenges in large scale mobile ad hoc networks (MANETs). In this paper, we propose a novel two-tier content-based routing protocol called CLONE (Community and Location aware cONtEnt based routing). In CLONE, we map the human community structure of social networks to MANETs. The whole network can be self-organized into communities based on the interest locality, so that most subscriptions inside a community can be served in an intra-community fashion, reducing the communication overhead and the response delay. Community construction is self-organized and completely distributed. Analytical and simulation results demonstrate the effectiveness of CLONE in large-scale MANETs.
