Offload Computation in Cloud Assisted Wireless Sensor Networks

Wireless Sensor Network consists of large number sensors used in the monitoring of physical and environmental condition. These sensors have low computing capability and limited storage. This limits its use in medical health applications. Additional Storage capacity can be provided by cloud computing. Cloud computing is a new paradigm in which computing resources such as processing servers, more memory, and large storage can be provided virtually. These resources are not physically present at the user’s location but appear to be present at current physical location. Cloud computing provides many advantages for businesses including low initial capital investment for new services and low maintenance and operation cost. The main objective of work is to provide authorized access to sensor information stored on cloud. Computation to validate authorized user is offloaded on remote server to increase life of sensor battery and sensor node. Computation offloading helps to transfer heavy computation to resourceful server outside the computing environment of user enhancing the performance of application using sensors.
