DEAD NODE DETECTION IN TEEN PROTOCOL: SURVEY

Avani Patel .
2014 International Journal of Research in Engineering and Technology  
Now a day's wireless sensor network has become an interesting research field. Network life time and energy efficiency are one of the main concerns for wireless sensor networks. Sensors are constrained in terms of battery power, storage, limited processing capacity etc. Because of these reasons new protocols are proposed for wireless sensor network. This paper only deals with cluster based hierarchical protocol TEEN (Threshold Sensitive Energy Efficient Sensor Network Protocol). The sensor

It transmits data based on hard threshold and soft threshold values. If the thresholds are not reached, then nodes will never communicate. The user will not get any data from network and will not come to know if all the nodes die. So, user will not be able to distinguish between how many nodes are alive or dead in network and will not be able to know about network lifetime. This paper deals with that node will be able to tell base station or sink before leaving network and base station will be aware of alive and dead nodes in the network.
