Energy efficient reputation mechanism for defending different types of flooding attack

Delay tolerant network solves technical challenges in the heterogeneous network that may lack end-to-end connectivity. However, due to the disconnected paths, message delivery is much dependent on the cooperation of intermediate nodes, but malicious nodes may inject other nodes with either bogus messages or copies of good messages. This causes relaying of unwanted packets, which in turn leads to draining the energy of the intermediate nodes....
