Wireless sensor networks (WSNs) are receiving significant attention. In which, there is a large number of studies are being done to address the problem of clock synchronization; where an adversary attacks a node and it can prevent the network from running certain clock-based applications. Due to the low capacity of wireless sensors, we propose in this article a new technique to synchronize the nodes of a system, through the random selection of a subset of neighbors instead of taking into account all the neighbors. Thanks to the proposed technique, we reduce the influence of malicious nodes, reduce the storage space, computation time, and energy consumption.

“…Security is an important part of many areas [7][8][9][10]. The data security process goes through many steps, starting from access control (Authentication, Authorization, and Audit) by using different mechanisms (LDAP, PKI, and roles management) and ending with our main interest which is data encryption in storage.…”

In recent years, Cloud Computing and Big Data have been considered the most attractive areas that are revolutionizing the IT world. Cloud Computing paradigm has recently appeared that allows running proprietary or difficult portable applications outside their original software environment on one or more virtual hardware platforms. Therefore, we are to developing such techniques which make it possible to secure communication between the communicating Cloud entities. These techniques must take into account several factors due to the data transmitted in this type of environment is proprietary and of significant size. Conventional data security techniques are not suitable for today's cloud usage. Hence, the main research of this thesis is to define an adaptable architecture with the aim to propose a scalable system that supports cloud services. We will define feasible security solutions dedicated to the Cloud computing context in order to robustly protect data stored in the Cloud. We are more precisely looking for working on NoSQL databases. We also intend to propose a secure solution based on the blockchain that has powerful features like decentralization, autonomy, security, reliability, and transparency.

“…It is a hard issue in distributed systems since the data are distributed among the various devices, which are geographically isolated as is the case for the IoT environments. All solutions require the use of a low-energy routing scheme [10,11,12,13].…”

IoT devices in a distributed environment that work on shared data still have a necessity for a locking mechanism to safely take turns while updating shared data. However, we no longer have the notion of mutexes when working in a distributed system. That is where distributed locks and leader elections mechanisms come into the picture. In addition to its low power consumption, BROGO (Branch Optima to Global Optimum) Leader Election Algorithm offers a lot of powerful features so it is well suited for the IoT environment. This algorithm decreases energy consumption by 95\% compared with basic techniques. In this paper, we employ BROGO as a use case in the cloud storage domain.
