Virtual Node based Optimal Route Selection using Modified ACO for Wireless Sensor Network

Abstract

As result of the various exclusive features, the Ad-Hoc network routing protocols not suitable to sensor networks. The energy efficiency requirement is an essential feature which differentiates the sensor network by others. The limited energy is reserved because of most of the battery operated sensors. A significant role is played by the radio communication as it is observed by analyzing the consumption of energy for node. Therefore, network lifespan enhanced an essential characteristic of the overall layers of the network protocol. As a result of limited scalability as well as dependency upon the repeated flooding, the optimum outcomes are not yielded by the conventional methods in which routing is established between the sensed data as well as sinks using the flat topology i.e., through the shortest routes of the additional data-centric methods like directed diffusion. Creating a classified network infrastructure within an essentially flat structure of MANET as well as the sensor network is the main objective of Virtual Backbone. A novel distribution heuristic procedure in which the Energy-Aware Ant colony Optimization based Virtual Backbone nodes (EA-ACO-VBN) is proposed in this method and it is used as communication infrastructure on behalf of WSN (wireless sensor network). An approach of threshold energy level as well as RSSI towards the participants of the virtual backbone is introduced in this paper. The responsibility of the backbone node in order to forward packets of additional nodes within network and the respective packets is the motive for this method.
