An ant colony optimization approach for reputation and quality‐of‐service‐based security in wireless sensor networks

Abstract

In wireless sensor networks (WSN), message security is an important concern. The protection of integrity and confidentiality of information and the protection from unauthorized access are important issues. However, due to factors such as resource limitations, absence of centralized access points, open wireless medium and small size of the sensor nodes, the implementation of security in WSN is a challenging task.In this paper, we propose a protocol, quality-based distance vector routing (QDV), for securing WSN using concepts based on Ant colony optimization ACO [1]. Two fundamental parameters---quality-of-service (QoS) and reputation [2]---are used. The high value of reputation of a node signifies that the node is trusted and is more reliable for data communication purposes. As a node shows signs of misbehavior, its reputation decreases, which, in turn, affects its quality-of-security QSec [2], thereby disabling the malicious nodes from gaining access to the network. By incorporating these two factors, we are able to distinguish the nodes present in the network. We, then, present a method to achieve "equilibrium" where the node is able to guarantee that its neighbors are secure. related to resource limitations, computation power, mobility and scalability, which need to be considered for secure message communication.There are many pieces of recent literature that discuss and propose different security solutions/protocols for use in WSN.

Providing trust in wireless sensor networks using a bio-inspired technique

“…As far as we know our model is on of the first ones (together with [10]) in applying a bio-inspired technique such as ant colony system (ACS) to develop a trust and reputation model for WSN.…”

“…Authors of [10] present an Ant Colony Optimization approach for reputation and quality-of-service-based security in WSNs. They specifically propose a quality-based distance vector protocol known as QDV, where the more reputation a node has, the more reliable it is for communication purposes.…”

Genetically optimized ACO inspired PSO algorithm for DTNs

“…Numerous research in the past has been devoted at achieving so [1] [11]. In the real scenario, ants travel vast areas without global view of the ground.…”

Reputation-based role assignment for role-based access control in wireless sensor networks

“…In previous years, a number of research works have been done and a number of others are also in progress both on access control models [1,4,5,7] and reputation-based systems [13][14][15][16]26,29] for wireless networks. Before we proceed towards describing our work, let us provide a brief review of some of the existing and popular access control and reputation based schemes that motivated our work.…”
