Adaptive ant colony network coding to neighbour topology based broadcasting techniques in MANETs

In Mobile Ad-Hoc networks, broadcasting is most frequently used operation in the network layer to forward the control packets to all its neighbour nodes. Source or Intermediate node transmits a rebroadcast packet to any or all other nodes whenever it receives, which could generate duplicate transmissions and it ends up in a significant downside `Broadcast Storm problem´. The researchers have been proposed 2-Hop Neighbour based protocol like DP, TDP, PDP and APDP to reduce broadcast storm in MANETs by choosing the minimum number of forwarding nodes using self pruning and dominant pruning. Nowadays, the researchers have been adapting Network coding idea (COPE) to neighbour topology based protocols which overcome the number of transmission by victimisation the using arithmetic operation i.e. XOR of packets. In this paper, we have made an effort to introduce Ant colony optimization to the COPE protocol with Pruning Algorithm. In this approach, we are using pheromone value to decide the packet combination. The pheromone value is evaluated based on the intersection of the sender packet list and Pruning algorithm forward node packet list. We have made an attempt to seek out the network coding gain in the high and low load situations and also in delay tolerant applications. We´ve shown simulation details in result section.
