A new weather routing method is proposed that accounts for ship maneuvering motions, ocean currents, wind, and waves through a time domain computer simulation. The maneuvering motions are solved by differential equations of motion for every moment throughout the voyage. Moreover, the navigation route, expressed in terms of a Bézier curve, is optimized for minimum fuel consumption by the Powell ...

Ad hoc mobile networks have dynamic topology with no central management. Because of the high mobility of nodes, the network topology may change constantly, so creating a routing with high reliability is one of the major challenges of these networks .In the proposed framework first, by finding directions to the destination and calculating the value of the rout the combination of this value with ...

An on-demand routing protocol for Mobile Ad hoc Network (MANET) is one that searches for and tries to discover a route to some destination node only when a sending node generates a data packet addressed to that node. In order to avoid the need for such a route discovery to be performed before each data packet is sent, such routing protocols must cache previously discovered routes. But the cache...

Routing of information is one of the most challenging issues in the field of Wireless Sensor Networks. In this paper we tried to show how implementing AI techniques specially reinforcement learning algorithms can be efficient in finding the optimal route and maximizing network life time; data packets in a wireless sensor network can be transmitted from every node as a source to the sink via the...

In this paper we have proposed a secure routing protocol based on AODV for multihop ad hoc networks. Our protocol is unique in the sense that it is capable of finding a secure end-to-end route free of any malicious entity, thus resisting an internal attack within the network either in the form of compromised or disloyal nodes. We propose to find a secure and efficient route to a destination bas...
