Re-Routing Strategy for Wireless Virtual Private Networks with CDMA Nodes

摘要

This paper attempts to develop a pioneering mechanism to re-route the data through an alternate path on the occurrence of an exigency in a Wireless Virtual Private Network (WVPN). The fact that Code Division Multiple Access (CDMA) technology facilitates large scale data transmission and is relatively free from interference augur the choice of CDMA nodes to examine the feasibility of a re-routing concept. It is designed to assuage a restricted usage of bandwidth to serve the elaborate needs of the growing traffic. The proposed Cluster based Adhoc On-demand Distance Vector (CAODV) methodology allows the Cluster Head (CH) to perceive a viable swap of the packets in the next possible minimum bandwidth path. The Network Simulator-2 (NS-2) simulation results are compared in terms of its performance metrics with that obtained in a normal environment to highlight the applicability of the projected strategy in the utility world.
