The smart grid is a giant "System of systems" which enables bidirectional communication methods and control capabilities
with innovative deployment of cyber systems and power infrastructures with the wireless communication technologies. The constant
interfering nature of jammers in the radio frequency in wireless networks creates jamming havoc in the smart grid communication
system. Hence the spread spectrum techniques that uses orthogonal multiple frequency and pseudo code channels must be used in the
smart grid communication systems to provide secure communication with required timing constraints for control messages. The critical
problem is to minimize the message delay for timely smart grid applications under the influence of vulnerable jamming attacks. For
solving this issue, we provide a reliable technique of transmitting adaptive camouflage traffic (TACT) which provides delay performance
guarantee for timely smart grid applications under any kind of worst case jamming attack. We first define a generic jamming process then
study the worst case methodology of jamming attacks using TACT which shows that the worst case message delay is a U-shaped
function of the network traffic load at the optimum. Further the collisions between the legitimate and camouflage traffic can be avoided
using message concatenation which again reduces the delay performance in the smart grid communication.

In this paper, we illustrated a comprehensive study of
minimizing message invalidation probability i.e. message
delay for the smart grid applications under worst-case
jamming attacks. We observed that the worst-case
message delay is a U-shaped function of the network
traffic load. We proposed a lightweight yet promising
method TACT, to generate the camouflage traffic to
minimize the message delay for smart grid applications
under any potential jamming attack and balance the
network load at the optimum point. Both the legitimate
and the camouflage traffic are unknown to receivers as
well as the attackers, which causes collisions between
legitimate and camouflage traffic transmissions. This can
be avoided using message concatenation technique which
concatenates multiple data into larger packets to reduce
protocol overhead and minimize collisions.
