EMCA: Efficient multicasting and collision avoidance in CC-MANETs

Content centric network (CCN) totally transform the host centric network architecture to content centric network architecture. Different researchers studied CCN for Mobile ad hoc networks (MANETs) for efficient communication. MANET in CCN faces various issues of flooding of interest packet and data packets, broadcasting on broken edges, power consumption, and reestablishment of the connection with mobile nodes. In this paper, we proposed an efficient multicasting and collision avoidance (EMCA) protocol in content centric MANETs (CC-MANETs). It minimizes the interest packet and data packet flooding in the network by applying check on the content store (CS) and pending interest table (PIT). EMCA also maintains the unique routing table (RT) at each node. RT extracts information from interest packets. If the path breaks during the data packet unicasting then data packet custodian node uses RT entries to select the second best path for unicasting. The simulation results of EMCA shows better results than AIRDrop because AIRDrop uses broadcasting on broken edges. EMCA achieves high throughput with less network load and minimum battery consumption. It also minimizes packet flooding in the network to ensure less packet collision rate. EMCA provides better content based communication protocol and ensures more successful communication in dynamic topology.
