A wireless sensor Network consists of a small battery operated sensors. After successful deployment of sensor nodes, it is often unfeasible to re-charge sensor nodes or replace batteries. Another major problem in wireless sensor network is the broken connectivity between sensor nodes due to power sources that drain out of power. To overcome these major drawbacks, optimized power consumption strategies need to be developed either by doing optimization in hardware or by using efficient software techniques. Power consumption constraints in WSNs require efficient task distribution among various...

Anand city is known as the Milk capital of India. The city has grown and urbanized at a rapid pace in past few decades. As a result number of vehicles has increased and industries were established in nearby areas. At this backdrop, the present study aims to find out the heavy metal concentration in the street dust, deposited dust on the leafs of plants growing beside the roadways and in suspended particulate matter of the ambient air.
