LP-ACO Technique for Link Stability in VANETs

The vehicular ad hoc networks consist of vehicles acting as nodes that convey one another to exchange data mostly regarding road and traffic conditions. These vehicles move at higher speeds in contrast to nodes in mobile ad hoc networks. Since information flowing in network is more of sensitive nature, the reliability of the data transmission becomes most important. These nodes use multi-hop communication to forward the traffic among each other. Therefore, stability of the links is of prime importance while data transmission using multi-hop communication. This was achieved by using Leapfrog algorithm, which helps to maintain the links between the intermediate nodes by choosing their common shortest neighbour. The capability of the network was compared depend upon routing overhead, packet delivery ratio and throughput. These parameters have shown to outperform the existing ant colony optimization technique used for routing.
