Wireless sensor networks (WSN) have become an integral part of our daily lives due to their small size, smart technology, lower cost, and wireless communication capabilities. In this paper, we propose a new WSN topology based on a hierarchical routing protocol. Additionally, we propose an enhancement to the DV-hop algorithm. Our proposed topology differs from existing approaches, and our enhanced algorithm improves upon the original DV-hop algorithm. The performance evaluations are globally satisfactory.

\ In this work, we propose a new hierarchical routing protocol called LCHREP (Layer and Cluster based Hierarchical Routing and Energy Optimization Protocol) that aims to minimizing energy consumption for wireless sensors network. LCHREP uses clusters formed on a layers and also uses multihop between these different layers. Results of simulations indicate that the proposed protocol allows better remaining energy after clusters heads selection, less amount of energy consumed in terms of sending packets. It allows also to reduce the number of nodes failed, and therefore to keep more nodes alive after sending packets.

Decentralized Social Networks are proposed to provide more privacy guarantee\  to the users. They avoid storing data in central servers. The profiles are important and critical objects of this type of network. They are stored in the user{\textquoteright}s devices. In order to ensure more availability, every profile is replicated in several devices. The different copies of any given profile stored in different devices are correctly updated with all the writes that happened in any single copy. Since the profiles undergo frequent writes, an important network load is generated during the update process. In this paper, we propose an update model based on the use of a log file to store the writ s. This reduces the size of the data exchanged between the devices storing the same profiles. Simulation results show that the proposed model is globally satisfactory.
