Fair Election of Monitoring Nodes in WSNs

Abstract

In this era of big data, of quantified self and of smart cities, wireless sensor networks are meant to be used every day, for all sort of applications. Made of tiny sensors, they collect data and communicate through wireless technologies. Because they may take part in sensitive or military applications, security is an essential matter in such networks. Confidentiality and authenticity can be ensured by the use of dedicated mechanisms. Focusing on availability, we propose here a new practical approach to protect the network against denial of service attacks thanks to the use of traffic monitoring agents called cNodes. The approach uses a fair election process of cNodes in accordance with classical criteria related to residual energies and the presence of compromised nodes which may have greedy or jamming behaviors. Results obtained from simulations show that this method is effective both in terms of detection and of energy conservation.

A New Defensive Technique Against Sleep Deprivation Attacks Driven by Battery Usage

“…Depending on the network's topology, this unplanned shutdown of some sensors can affect the availability of the network. In [Monnet et al 2015], Monnet et al proposed to use traffic monitoring agents in a clustered WSN to detect potential DoS attackers in the network. These agents need to be trusted, and they need to be elected considering the residual energy of all the nodes inside a cluster to prevent the election itself from being responsible for a DoS.…”

“…If the power consumption surpasses a predefined threshold, the device calculates and enters to the sleep mode for the time it needs to rectify its consumption. Compared to related works [Hei et al 2010, Monnet et al 2015, Alampalayam and Kumar 2003, Abdullah et al 2019, Nash et al 2005, Jacoby and Davis 2004, the proposed technique runs directly on low-power sensors, without depending on external agents, regardless a network architecture to prevent a sleep deprivation attack of having effect on the sensor battery lifetime.…”

Dynamic and adaptive detection method for flooding in wireless sensor networks

“…Hammal et al have proposed an iterative mechanism to elect Cnodes by using a democratic process and based on the residual energy nodes. Once clusters are formed, initialization phase starts and each node sends the residual energy value to its CH, and each node acts as a Cnode and starts controlling its neighbors and keeps transmitting data at the same time.…”
