In several wireless sensor network the energy conservation is a major problem .In this WSN once the energy gets lost the sensor moves to die condition and so it cannot possible to replace the battery in sensor. So energy conservation is difficult in sensor network .The node which is closer to the base station has the responsible for collecting data from the entire node and send it to the base station .such node is called as ischolar_main node or sink node (e.g., tree topology). This paper achieved the fast data collection by keeping the sink node always in the busy state .In this converge cast algorithm is used which contains Aggregated converge cast and Raw-data converge cast algorithm. TDMA (Time Division Multiple Access) are better fit for fast data collection since they can avoid collision and retransmission of data .Fast data collection with the aim of minimize the schedule length for aggregated converge cast.

When target devices are transmitting a reactive jammer jams the wireless channel; Reactive jamming is harder to track and compensate against the constant jamming methods. Frequency Hopping Spread Spectrum (FHSS) and Direct Sequence Spread Spectrum DSSS) have been widely used against Jamming attacks. If high power transmitter or frequency channel is jammed then both these method will fail. We use broad band and high power reactive jammer to avoid jamming attacks. In this proposed method we use bit trickle method to avoid jamming. Bit Trickle is a method which is used to find attackers when using broadband communication between transmitter and receiver. Users having secret key to access the data from anti jammer. Once the security key is correct then only the transmission occurs.
