***, *** radio links empowered by Wi Fi, Wi MAX etc have been recently exploited to build maritime *** mesh networks to provide internet services to *** users. However, because of the mobility of the vessels/ships and the large *** distances, nodes in the maritime network are frequently disconnected, forcing data communication in the maritime mesh networks to be opportunistic and ***. In this paper, we present Lane Post, an optimization approach for maritime *** routing protocol. We exploit the shipping lane information to predict the rendezvous opportunities of the ships to optimize the route selection in *** routing. In particular, we show that when the shipping lane information is available, an opportunistic routing graph(ORG) for each ship can be constructed to predict its *** data routing opportunities to the other ships or to the shore. Based on the ORG, we develop an optimal route protocol(i.e., Lane Post) for each ship to minimize its delay of *** packet delivery via dynamic programming. We discussed the ways of collecting shipping lane information by centralized method or distributed *** proposed Lane Post protocol was evaluated by ONE, an *** *** network simulator, which shows its dramatic performance improvement in terms of delay reduction compared to the *** opportunistic routing protocols.
