An ACO-Based Efficient Stagnation Avoidance Methodology for MANETS

摘要

The efficiency and behavior of a MANET depends on how well information can be passed around and delivered using Ant colony optimization (ACO). ACO algorithm heavily depends on how efficiently the pheromone is handled. Controlling pheromone is a challenging task. In this paper, an efficient pheromone decay technique is adopted which can be achieved by using stability factor '△'. The stability factor is the ratio of number of Hello packets received to the number of Hello packets sent. This dynamic changing ratio will help to decide the extent of pheromone to be decayed. The technique adopted is also termed as altered exponential decay technique (AET).
