Singhal's daughter Kajal, is the wife of corrupt lawyer Ravi, who can win almost any case. During a court case, he falsely accuses and gets a righteous man convicted of corruption, and he commits suicide out of disgrace. His son Major Karan swears revenge and one day after a party that Kajal and Ravi attend, he fires a pistol directly at Ravi, but his wife Kajal (Mahima Chaudhry) comes in to save her husband using her body as a shield. Karan fires a second time, and Ravi is shot in the spinal cord and loses part of his memory, and the doctors diagnose him with 'retrograde amnesia".
Chaudhary, last seen in a fracas with Subhash Ghai, gives a performance to make her mentor proud. Much of the fire in Daag comes from her. Dutt's finely chiselled body is put to good use but his role is confined to glowering and shooting. Singh, a bland hero, makes a surprisingly good villain. Every Bollywood director insists that his film is hat ke (different). Daag re-jigs the formula just enough to be middling entertainment.
where θi is the environment variable, such as loudness, temperature, light intensity and humidity. αi is its weight value. For example, in the case of a wildfire detection system, the weight of temperature and light intensity would be higher than that of loudness.
Furthermore, light intensity and temperature are usually low in normal situations. In this case, the system does not need to send data continuously. Therefore, using the data ferry method to deliver the data reduces the energy consumption with no setbacks. However, if a wildfire occurs, the light intensity and temperature of the surveillance area will be increasing, and an immediate and continuous data report is required to understand the situation with accuracy. In this case, continuous data transmission with a multi-hop network is required.
