| dc.description.abstract | An ad hoc network is a collection of wireless mobile nodes dynamically forming a temporary network without any fixed infrastructure like access points or base stations. Each node in ad hoc network is willing to forward data for other nodes, and the determination of which nodes forward data is made dynamically based on the network connectivity. Mobile ad hoc networking can offer multiple advantages in various environments through its flexibility and its special nature. One such environment is maritime communications. The MARCOM Project currently has shown that a definite protocol simulation of maritime ad hoc network is needed, which focus on the hand-over problems, as well as the mixture of fixed and mobile nodes interconnected via wireless links to form a multi-hop ad-hoc network, amongst ships, marine beacons and buoys. In this thesis, it is mainly focus on comparing simulation performance between AODV and OLSR. The simulation results have shown that in definite maritime ad hoc networks neither of them suits without modifications. The scenarios are built on maritime which means the protocols have to be workable in the special situation at sea. These simulations in my thesis do not give a general view of the protocols, but instead test certain characteristics of the protocols in maritime scenarios. If time allows, there could be more discussion about enhancements needed for both AODV and OLSR, like position aware and parameter aware. | en |
