Redeployment of Randomly Deployed Wireless Mobile Sensor Nodes

Khalil Mougou Saoucène Mahfoudh Pascale Minet Anis Laouiti

Wireless sensor networks (WSN) are generally randomly deployed in a given area. This initial deployment does not achieve neither area coverage, nor network connectivity. Thus, a redeployment algorithm has to be applied in order to achieve these two goals. This algorithm should meet performance criteria like saving energy and achieving stability. Our contribution in this paper is the design of DVFA, a distributed redeployment algorithm based on virtual forces. We simulate its behavior with NS2 and compare its performances with CVFA, a centralized version also based on virtual forces.

Data gathering architecture for temporary worksites based on a uniform deployment of wireless sensors

International Journal of Sensor Networks (2015)

Ines Khoufi Saoucène Mahfoudh Pascale Minet Anis Laouiti

Data management is an important issue in wireless sensor networks. However, the data gathering process may be unsuccessful in disconnected or random networks: some data gathered cannot be delivered to the sink, coverage holes may occur and result in missing data. To cope with this problem, we propose two distributed redeployment algorithms (distributed virtual forces algorithm (DVFA) and adaptive distributed virtual forces algorithm (ADVFA)), based on virtual forces, that provide a uniform deployment of sensor nodes. Both ensure full area coverage and network connectivity.We define a three-tier architecture where after the execution of a redeployment algorithm, sensor nodes are uniformly deployed to monitor a temporary worksite. We compute the optimal number of sensors needed to cover an area. Using this result, we parameterise DVFA and evaluate its performances. We then propose ADVFA to cope with DVFA drawbacks (e.g., node oscillations). ADVFA outperforms DVFA, considerably reducing the distance travelled by nodes and then maximising network lifetime by saving energy.

OCARI for industrial wireless sensor networks

Marc-Henri Bertin Adrien van den Bossche Gérard Chalhoub Tuan Dang Saoucène Mahfoudh

OCARI is a wireless communication technology targeting applications in harsh environments such as power plants and warships. It supports mesh topology and provides a deterministic MAC access for time-constrained communications as well as energy efficient communications for an increased network lifetime. Based on the PHY layer of IEEE 802.15.4, it supports the ZigBee APS and APL primitives and profiles, ensuring compatibility with existing applications.

Node activity scheduling in wireless sensor networks

Saoucène Mahfoudh Pascale Minet

Wireless sensor networks have resources of limited capacity (e.g. bandwidth, processing power, memory and energy). That is why these resources should be efficiently used. Node activity scheduling is a technique that allows nodes to alternate sleep and awake states. This technique spares energy insofar as the sleep state is the state using the smallest power. Moreover, by allowing several nodes to transmit simultaneously without interfering, spatial reuse of the bandwidth is obtained. Furthermore with a smart schedule, data gathering can be done in a single cycle. All these reasons render node activity scheduling very attractive in wireless sensor networks. We propose in this paper a three-hop coloring algorithm for data gathering applications. Simulation results allow us to evaluate the number of colors needed to color all network nodes and hence to determine the reduced size of the activity period in each polling cycle. The complexity of our algorithm is given in terms of number of messages sent per node. We can then determine the network configurations for which coloring brings interesting benefits, namely a more efficient use of the bandwidth and the node energy, as well as a shorter delay to collect data ensuring their time consistency.

An Energy Efficient Routing Based on OLSR in Wireless Ad Hoc and Sensor Networks

Saoucène Mahfoudh Pascale Minet

Energy efficiency is a key issue in wireless ad hoc and sensor networks. Several directions have been explored to maximize network lifetime, among them energy efficient routing. In this paper, we show how to extend the standardized OLSR routing protocol, in order to make it energy efficient. To take into account residual node energy, three new selection algorithms of multipoint relays, based on the minimum residual energy are evaluated, the best one is chosen. This OLSR extension selects the path minimizing the energy consumed in the end-to-end transmission of a flow packet and avoids nodes with low residual energy. We compare this extension with a two-path source routing strategy (with different links or different nodes). An extensive performance evaluation shows that this energy efficient extension maximizes both network lifetime and user data delivered.

Improving Collaborative Intrusion Detection System Using Blockchain and Pluggable Authentication Modules for Sustainable Smart City

Sustainability (2023)

Rajeev Kumar Gupta Vedant Chawla R. K. Pateriya Piyush Kumar Shukla Saoucène Mahfoudh

The threat of cyber-attacks is ever increasing in today’s society. There is a clear need for better and more effective defensive tools. Intrusion detection can be defined as the detection of anomalous behavior either in the host or in the network. An intrusion detection system can be used to identify the anomalous behavior of the system. The two major tasks of intrusion detection are to monitor data and raise an alert to the system administrators when an intrusion takes place. The current intrusion detection system is incapable of tackling sophisticated attacks which take place on the entire network containing large number of nodes while maintaining a low number of login attempts on each node in the system. A collaborative intrusion detection system (CIDS) was designed to remove the inefficiency of the current intrusion detection system which failed to detect coordinated distributed attacks. The main problem in the CIDS is the concept of trust. Hosts in the network need to trust the data sent by other peers in the network. To bring in the concept of trust and implement the proof-of-concept, blockchain was used. Pluggable authentication modules (PAM) were also used to track login activity securely before an intruder could modify the login activity. To implement blockchain, an Ethereum-based private blockchain was used.

Peer to Peer Botnet Detection Based on Network Traffic Analysis

Suzan Almutairi Saoucène Mahfoudh Jalal S. Alowibdi

One of the most serious cyber-security threats is the botnet. The botnet runs in the background of the compromised machine and maintains the communication with the C&C server to receive malicious commands. Botnet master uses botnet to launch dangerous attacks. %such as Distributed Denial of Service (DDoS), data stealing and spamming. This paper addresses the problem of detecting P2P botnet flow records from P2P application within Netflow traces and activities in the network. We propose a technique that is capable of detecting a new P2P botnet in early stage. This technique has been evaluated with a collection of real malicious and legitimate datasets. Our algorithm preprocesses and extracts features to differentiate the botnet behavior from the legitimate behavior. The results of our experiment show a high level of accuracy and a low positive rate.

Energy Efficient Routing and Node Activity Scheduling in the OCARI Wireless Sensor Network

Future Internet (2010)

Saoucène Mahfoudh Pascale Minet Ichrak Amdouni

Sensor nodes are characterized by a small size, a low cost, an advanced communication technology, but also a limited amount of energy. Energy efficient strategies are required in such networks to maximize network lifetime. In this paper, we focus on a solution integrating energy efficient routing and node activity scheduling. The energy efficient routing we propose, called EOLSR, selects the route and minimizes the energy consumed by an end-to-end transmission, while avoiding nodes with low residual energy. Simulation results show that EOLSR outperforms the solution selecting the route of minimum energy as well as the solution based on node residual energy. Cross-layering allows EOLSR to use information from the application layer or the MAC layer to reduce its overhead and increase network lifetime. Node activity scheduling is based on the following observation: the sleep state is the least power consuming state. So, to schedule node active and sleeping periods, we propose SERENA that colors all network nodes using a small number of colors, such that two nodes with the same color can transmit without interfering. The node color is mapped into a time slot during which the node can transmit. Consequently, each node is awake during its slot and the slots of its one-hop neighbors, and sleeps in the remaining time. We evaluate SERENA benefits obtained in terms of bandwidth, delay and energy. We also show how cross-layering with the application layer can improve the end-to-end delays for data gathering applications.
