Survey of Selfish Node Detection in Wireless Sensor Networks Using Watchdog Method

Zigbee protocol is used to send the packet from source to destination. It does not have any routing table and route discovery method. Tree topology method followed by ZigBee Tree Routing (ZTR). But it will not be provided the best routing path from source to destination. Shortcut Tree Routing (STR) can be used to provide best optimal path. STR will calculate the hop count from source to destination with help of Zigbee protocol. Zigbee protocol having the hierarchical addressing format. Shortcut Tree Routing method does not have security procedure option. Because of this our technique will be protected in safe manner. Most of the sensor networks are having self centered node. Due this there is a possible to get performance degradation between source and destination. These selfish node should be identified to get make better formance for sensor networks. Main theme of our paper is to find selfish node from the networks and providing best route between source to destination. Our aim is to get efficient data delivery using Watchdog method.
