Enhancement of Power Efficient Gathering Model for Wireless Sensor Networks

Wireless Sensor network set new horizon for current research community. As we know it has large number of applications in almost every field of life. A Wireless Sensor-Actuator Network (WSAN) is composed of sensor and actuator nodes interconnected in a wireless channel. Sensor nodes can deliver messages to only nearer nodes due to weak radio and messages are forwarded by sensor nodes to an actuator node. Messages sent by nodes might be lost due to collision and noise. In current scenario wireless sensor network is widely popular for forming a connection between physical world and the virtual world. To avoid tedious tasks found in   the technical process, it is important to focus on the energy levels associated with the network system as well as data. As we know these sensor devices rely on battery power and may be placed in hostile environments replacing them becomes a tedious task. Thus improving the energy and data transmission rate of these networks becomes important. We work on data gathering technique because data security is very important in wireless field. Here we enhance the Power efficient gathering model for wireless sensor network by reducing the delay and energy consumption. Here we improve the speed of data transmission and ensure secure delivery of data to the desired receiver.
