D0S-Resilient Data Aggregation protocol for wireless sensor network

This project is about handling DoS (Denial of Service) that may appear in wireless sensor network especially during aggregation process due to a compromised node. The network will be built into a tree topology and some cryptographic techniques need to be used such as Digital signatures, secret shares, Hash-based Message Authentication code (HMAC) to detect the compromised node (or the malicious node) and make it inactive for some time T=10min in order to maintain the proper functionality of the network. This T will be subtracted from 1 for each query iteration and the compromised node that has been assigned to a time T can only rejoin the network when T becomes 0.
