Offload computation in cloud assisted Wireless Sensor Networks

摘要

Wireless Sensor Network formed by huge number sensors, used to detect the physical conditions and environmental conditions. These sensors have very small computing capability and less storage. This limits its use in medical health applications. Additional Storage capacity can be achieved by cloud computing. Cloud computing is one of the innovative paradigm which provides computing resources such as processing servers, more memory, and large storage, that can be provided virtually. These all resources are not present at the user's location but appear to be at current physical location. The objective of this work is to provide access to authorized user for retrieval of sensor information stored on cloud. Computation to validate authorized user is offloaded on remote server to increase lifetime 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.
