Recent advances in the wireless sensor network introduction many protocols specially designed for sensor networks, different traffic models and energy efficiency techniques in Wireless Sensor Networks (WSN) so far. Most of the clustering protocols planned for the nodes are stationary. But, in applications like habitat monitoring those clustering mechanisms are invalid, so the static environment...

Wireless Sensor Network has the potentiality to link the physical world with the virtual world by forming a network of sensor nodes. Energy efficient object tracking is one of the main design issues for wireless sensor networks. Energy efficiency is required as the whole WSN is dependent on the power of batteries and the object tracking is required for checking the varying speed of target, targ...
