An Overview about QoS Improvement by Enhanced ACO in Hybrid and Reactive Routing Protocols in MANET

Abstract: Adhoc networks are networks of wireless connectivity between various hops, frequently changing network topology and the efficient dynamic routing protocols that are needed and plays an important role too. Proactive, Reactive and Hybrid are different classes of routing protocols. An on-demand and Hybrid routing strategy are popular routing category in mobile adhoc networks. On comparing the other protocols the ZRP that is Zonal routing protocols the hybrid which provide best node mobility performances. Here the Ant colony optimization approach is introduced in order to get an optimal path selection in network scenario. It is essential for the tactical communication that needs the essential quality of service. By providing enhanced Ant colony optimization the pheromone value that is the behaviour of ants used here are continously updated that is enhancement by using the parameters like residual signal strength, energy, hop count, etc... to get the optimal results which helps to get a very good performance results while in a highly mobile tactical environment too. In this work an attempt of review has been made to study the behaviour of an enhanced technique combining Hybrid routing protocol and the Ad-hoc On Demand Distance Vector protocol with Ant Colony Optimization (ACO) that can increase various QoS requirements.
