Throughput analysis of single gateway association in wireless mesh network with multiple gateways

This scenario of multiple gateways leads to improvement in throughput of overall network. But some criteria is required based on which the nodes are to be associated to a gateway. Associating to the nearest gateway may not be always the best choice. We present here an algorithm for associating a node to one of several available gateways. | International Journal of Computer Networks and Communications Security VOL. 3, NO. 12, DECEMBER 2015, 447–450 Available online at: www.ijcncs.org E-ISSN 2308-9830 (Online) / ISSN 2410-0595 (Print) Throughput Analysis of Single Gateway Association in Wireless Mesh Network with Multiple Gateways GEETA J.

E-mail: 1tripathi.geetaj@gmail.com, 2armahajan@rediffmail.com ABSTRACT Wireless mesh network (WMN) has become widely accepted technology in recent decade [1]. Low cost, simplicity and availability of the Internet without actually getting directly connected to the broadband services, are few of the advantages that can be counted on for popularity of WMN. Mesh nodes get access to the Internet through a special device called Gateway. Even one gateway may be sufficient to provide broadband facility to a number of nodes in its range. With addition of more gateways, the range of covering more nodes is increased. This scenario of multiple gateways leads to improvement in throughput of overall network. But some criteria is required based on which the nodes are to be associated to a gateway. Associating to the nearest gateway may not be always the best choice. We present here an algorithm for associating a node to one of several available gateways. Throughput is one of the key performance metrics for many applications. In this paper we have analyzed the network on this performance metric for nearest gateway scheme and for proposed scheme. The proposed scheme has shown better performance especially for densely populated mesh nodes near gateway.
