IMPROVING QoS IN DELAY TOLERANT MOBILE AD HOC NETWORK USING MULTIPLE MESSAGE FERRIES
Most ad hoc network routing algorithms are designed primarily for networks that are always connected. While it is certainly desirable to maintain a connected network, various conditions may cause a mobile ad hoc network to become partitioned. If the partitions last for a long duration of time, then it is not possible to deliver a packet from source to destination. To deliver messages in a partitioned network, new routing approaches were proposed for delivering data using message ferries and/or gateways. This paper analyzes various parameters of the routing scheme called Routing with Multiple Message Ferries and Gateways (MMFGW) which eliminates online collaboration between all the communication entities in the network. This paper also investigates the results of simulations, by comparing the performance of our protocols which uses message ferries proposed previously with epidemic routing protocol. The simulation analysis shows that, delivery ratio of MMFGW improves from 35% to 50% with optimal latency and overhead ratio.
