SCA - An energy efficient transmission in sensor cloud

Abstract

Sensor cloud is an emerging technology which integrates wireless sensor network with cloud environment. The major issues to be addressed in the sensor cloud are storage and transmission. The existing compression algorithm inappropriate for small size files. The sensor data taken from different sensor are compressed based on their similarity but it is not appropriate when large numbers of sensors in the network. In this paper, we proposed an energy efficient middleware model for sensor cloud named as senud controller which is the combination of sensor gateway and cloud gateway. It can deal with the adverse situation in case of continuous and long duration monitoring of data. Senud Compression Algorithm (SCA) reduces the replication of data and suitable for the numerical data compression. It is basically designed for numerical valued sensor data that supports large voluminous data collection in an efficient manner.
