Simulation of Replica Allocation Algorithm in Adhoc Networks with Timestamping Method

Mobile Ad Hoc Network (MANET) is a self-organizing, rapidly deployable network of wireless nodes without infrastructure. Mobile nodes of a MANET also function as routers. Disconnection often occurs due to mobility and causes frequent network division. Disconnected partitions decrease data accessibility. In replica allocation, the data items will be copied or replicated and will be stored in more than one machines so that even if a machine cannot access the owner of a data, it can access the data from some other machines which have the replica. In this paper we have simulated a replica allocation algorithms using OMNeT++ and also used the time stamping property to avoid inconsistancies of data in the network.
