Wireless sensor network is a collection of homogeneous/heterogeneous wireless devices used to monitor the changes in the surrounding of the wireless device. Each wireless device present in the network has the capability of sensing the changes in the surrounding environment. Homogeneous sensors are those which have same computational power, energy, etc. Each node is battery powered which is used to transmit the sensed data over the network. So efficient transmission of data in wireless sensor network is important and to transmit the data unaltered over the network to the receiver security is important.
