Quality of Service (QoS) guarantees must be supported in a network that intends to carry real-time multimedia traffic effectively. A key problem in providing QoS guarantees is routing which consists of finding a path in a network that satisfies several constraints such as bandwidth, delay, delay jitter, etc. This paper proposes a novel QoS routing scheme called AntNet-QoS which provides QoS by ...

Antnet is a software agent based routing algorithm that is influenced by the unsophisticated and individual ants emergent behaviour. In real life, ants deposit some kind of chemical substance to mark the path that they used. Then on their way back they choose the path with the most pheromones which becomes the shortest path. Ants (nothing but software agents) in antnet are used to collect traff...

Routing algorithm is the key element in networks performance and reliability, therefore, there is a need for an algorithm to manage traffic flows and deliver packets from the source to the destination in a realistic time. A modification algorithm has been presented called Subset Nodes Based AntNet. In the Subset Nodes Based AntNet, a routing tables maintained at each node is used to get a subse...

Antnet is a software agent based routing algorithm that is influenced by the unsophisticated and individual ants emergent behaviour. Ants (nothing but software agents) in antnet are used to collect traffic information and to update the probabilistic distance vector routing table entries. One of the major problems with antnet is called stagnation and adaptability. This occurs, when the network f...

Antnet is an agent based routing algorithm based on real ants' behavior. Ants are able to find shortest path to food source .In real life, ants drop some kind of chemical substances to mark the path that they used. Then on their way back they choose the path with the highest pheromones which becomes the shortest path. But Antnet Algorithms may cause the network congestion and stagnation. Here, ...

A distributed GA (Genetic Algorithm) is designed for the packet switched network routing problem under minimal information, i.e., without information exchange, every node only knows the existence of its neighboring nodes. The requirements of such a problem mean that intelligent packets are required to possess more intelligence than was the norm. To this end a distributed GA approach is develope...

A number of routing algorithms based on the ant-colony metaphor have been proposed for communication networks. However, there has been little work on the performance analysis of ant-routing algorithms. In this paper, we compare the performance of AntNet, an ant-routing algorithm, with Dijkstra’s shortest path algorithm. Our simulations show that the performance of AntNet is comparable to Dijkst...

In this paper we present AntNet, a novel adaptive approach to routing tables learning in packet-switched communications networks. AntNet is inspired by the stigmergy model of communication observed in ant colonies. We present compelling evidence that AntNet, when measuring performance by standard measures such as network throughput and average packet delay, outperforms the current Internet rout...

Antnet is a software agent-based routing algorithm that is influenced by the unsophisticated and individual ant’s emergent behaviour. The aim of this chapter is twofold, firstly to introduce improvements to the antnet routing algorithm and then to critically review the work that is done around antnet and reinforcement learning in routing applications. In this chapter a modified antnet algorithm...
