Prolonging the network lifetime depends on efficient management of sensing node energy resource. Energy consumption is therefore one of the most crucial design issues in WSN. Hierarchical routing protocols are best known in regard to energy efficiency. By using a clustering technique hierarchical routing protocols greatly minimize energy consumed in(More)
Many applications that use sensor data from a wireless sensor network (WSN) require corresponding node position information as well. Additionally, some routing protocols use position to determine viable routes. Several localization algorithms have been proposed which can be categorized as: range-based and range-free algorithms. In this paper, we propose a(More)
A clustering algorithm is a key technique used to increase the scalability and lifetime of the Wireless Sensor Networks (WSNs). In this paper, we propose and evaluate a distributed energy-efficient clustering algorithm for heterogeneous WSNs, which is called Position-Based Clustering (PBC). This protocol is an improvement of LEACH-E. In PBC, the(More)
With the emergence of cloud computing, the concept of information security has become a major issue. Indeed, the security of such a system is the greatest concern of computer scientists, providers of cloud and organizations who want to adopt and benefit from these services. Cloud computing providers must implement concepts ensuring network security,(More)
With the emergence of cloud computing, the concept of trust has become a major issue. Indeed, the key challenge is to ensure to customers that the selected cloud provider may store and process the raw data safely. If this is a storage service, data can be encrypted before sending them to the cloud server; in this case, data confidentiality is assured.(More)
