Wireless Sensor networks are dense wireless networks of small sensors, which collect and disseminate environmental data. The collected data or information is processed, interpreted and accordingly actions are performed. Wireless sensor networks facilitate monitoring and controlling of physical environments from remote locations with better accuracy. One of the major issues in wireless sensor network is to maximize the lifetime of the network by minimizing the energy consumption by the node. In this paper the authors have proposed a technique CTT (Cooperative Threshold Transition) this process take care of energy consumption into the network and because of this power management can be utilize in an efficient manner so that life time of a network is increases.
