A key updating model in DTMSN with variable contact rate
Rao Jia · Journal of Sichuan University · 2013
The key updating ensures the safety of data transmission in Delay Tolerant Mobile Sensor Networks.Existing key updating models in DTMSN are based on the assumption that node contact rates are equal.By analyzing the characteristics of the key updating module based on forwarding nodes,this paper proposes a key updating model in DTMSN with variable contact rate and validates it by simulation.
