Enhanced Quality of Service Based Routing Protocol Using Hybrid Ant Colony Optimization and Particle Swarm Optimization

Abstract

The main problem of QoS routing is to setup a multicast hierarchy that may meet particular QoS constraint. In order to reduce the constraints of the earlier work a new improved technique is proposed in this work. In the proposed technique the issue of multi-cast tree is eliminated using clustering based technique. First of all multi-radio and multichannel based clustering is deployed and these cluster head are responsible for the multicasting. It will diminish the overall energy consumption of nodes and complexity of intelligent algorithms. The path will be evaluated based upon the ant colony optimization. Thus it has produced better results than other techniques.Keywords: QoS, Multicast, Ant colony optimisation, clustering. 1.IntroductionA Mobile Ad-hoc Network is an accumulation of independent mobile nodes that can communicate together via Radio Lake. Your mobile nodes which has been in radio selection of each various other could right communicate, whereas others needs the aid of intermediate nodes to route his or her packets. The entire node carries a radio user interface to connect jointly. These networks usually are fully distributed, and perform at any place without the aid of any fixed infrastructure as gain access to points or base areas. Figure 1 shows a simple ad-hoc network having 3 nodes. Node 1 in addition to node 3 isn't within range of each and every other, however the node 2 enables you to forward packets between node 1and node a couple of. The node 2 will behave as a router in addition to these three nodes in concert form an ad-hoc system.. Fig. 1 Example of mobile ad-hoc network 1.1 MANETs characteristics 1) Dispersed operation: There isn't background network for that central control in the network operations; the control in the network is distributed one of the nodes. The nodes associated with a MANET should cooperate with each other and communicate among themselves and each and every node acts to be a relay as essential, to implement specific functions for example routing and security.2) Multi get routing: When a node endeavours to send facts to other nodes that is out of its communication range, the packet the packet need to be forwarded via one or more intermediate node.3) Autonomous fatal: In MANET, each mobile node is an independent node, which will function as both a host and a router. 4) Vibrant topology:Nodes are unengaged to move arbitrarily using different speeds; so, the network topology might change randomly and also at unpredictable time. The nodes in the MANET dynamically determine routing among themselves since they travel around, establishing their unique network. 5) Light-weight terminals:Within maximum cases, the actual nodes at MANET are generally mobile with much less CPU capability, minimal power storage and also small memory measurement. 6) Shared Physical Medium:The wireless communication medium is obtainable to any entity with all the appropriate equipment and also adequate resources. Keeping that in mind, access to the channel is not restricted. Advantages of M...
