摘要：In Wireless Sensor Network, dynamic cluster based routing protocol is mostly used. It is a network of battery operated, tiny, mostly homogeneous sensor nodes having limited memory, processing power with wide applicability in the area of military, weather forecasting etc. As it is battery operated, it requires energy awareness in all layers of the networking protocol stack to prolong the life time of the network. Protocol designed for such sensor network must efficiently use limited bandwidth and energy of the sensor node. In this paper energy is saved by minimizing no of Communication by lowering the cluster reelection using a Backup node concept and EX-APTEEN is a hybrid protocol like APTEEN (Adaptive Periodic Threshold Energy Efficient Sensor Network Protocol).Our Protocol uses a Enhanced TDMA Schedule to efficiently handle query handling with a queuing mechanism for heavy load. It has the capability of querying the network through base station and through a network nodealso.uteru
