Route Optimization using Membrane Computing in Opportunistic Network

The most prominent evolution of Mobile Ad hoc Networks (MANETs) is opportunistic networks. The nodes try to make contact with each other within a network even under the conditions when there exist no any real route for the transference of information. Unlike conventional nodes in MANETs, the nodes in opportunistic networks may or may not be aware to the desired route. The disconnection or reconnection of the connections between the nodes in opportunistic networks is very common, hence for this reason the routes are built dynamically. The contacts between the nodes are discontinuous in nature. Therefore, the nodes which are intermediate in nature can take out the responsibility of transference of data or information during any blackout and again transmits the data after the re-connectivity of connections. Thus, the major concern in opportunistic networks is optimization of route. In this paper, the concept of Membrane Computing is being modeled with opportunistic networks in order to optimize the route between the nodes for the flow of data or information. The simulator used for the process of simulation is Network Simulation NS-2.35. Also, the integration of membrane computing algorithm within DSR protocol provides the better and efficient performance for packet delivery ratio and reduces end to end delay. The simulation results show that the proposed protocol DSR outperforms the performance of AODV protocol when get used in opportunistic networks along with Membrane Computing.
