Abstract
Time synchronization is required in wireless sensor networks in order to improve its performance. This improvement could be noticed in terms of energy, storage, computation, shared resources or bandwidth. One of the main applications in WSNs has been to decrease the energy consumption. A wireless network can save energy with this feature, but if this synchronization is corrupted, it could cause a worse behavior. Firstly, we will analyze which are the most important time synchronization issues. Then, a secure time synchronization method will be presented for group-based wireless sensor networks to avoid malicious attacks. The synchronization technique is based on a system model for secure intra-group synchronization. This system will use simple messages, where nodes of each group will exchange several parameters like time stamps, groupID, etc. in order to make a secure system. The system proposed has high scalability, due to group-based feature, while saves energy thanks to the designed synchronization technique. In order to test our proposal we will simulate several situations to show the performance of our synchronization algorithm.
