Secure and Reliable Data Transmission in Wireless Sensor Network: A Survey
Wireless sensor network increases its application in industrial field as well as in consumer application very rapidly. Its growth increases day by day. Sensor node normally senses the physical event from the environment such as temperature, sound, vibration, pressure etc. Sensor nodes are connected with each other through wireless medium such as infrared or radio waves it depends on applications. Each node has its internal memory to store the information regarding the event packets. Basically this whole sensor network called sensor net is working in a distributive manner, sensor nodes are deployed in a huge area and use to send data packet in broadcast manner. This data packet finally reaches to the base station or called sink and vice versa.
