Effective Transmission of Messages in WANETs Adopting Node Stamping Technique

Abstract

A Wireless Ad hoc Network (WANET) is a form of Local Area Network (LAN). In WANET, all nodes can typically construct a network by connecting two or more wireless networks without the need of a fixed infrastructure, which instead require either a Router or an Access Point. Since the devices can establish a connection in an ad hoc network and use other’s resources apparently through P2P (peer–to–peer) or point–to–multipoint means, there is no need for a base station for establishing a topology. Broadcasting is the technique used in WANETs for communication between the nodes. Because of the absence of fixed infrastructure the basic problem faced by this technique is broadcast storm. This broadcast storm is caused because of the flooding of messages in the nodes. Node stamping technique is proposed and the objective to enhance the performance of the broadcast method. This technique uses the stamp list, which records the updated information of about all the nodes that have been visited and the neighboring nodes to eliminate the unnecessary messages. Another work proposed is to minimize the node stamping cost. For reducing the cost, reducing the count of stamps and various techniques for compression are proposed. The results of the proposal have been compared with existing algorithms Blind Folding (BF), Self–Pruning (SP) and Scalable Broadcast Algorithm (SBA). It is observed that proposal node stamping has shown enhancement in performance and efficiency in the broadcast methods. This proposal also achieved in minimizing the cost of node stamping.
