Wireless sensor networks have been identified as one of the most important technologies for the 21st century. They consist of nodes with wireless communication, sensing, and computation capabilities. Earlier paper predicted that the size of sensor will smaller and smaller like a dust and will not use IP protocol due to inefficiency reason. But today, wireless sensor evolution takes different path. The sensor size is become smaller as predicted but it is become dependent devices, the smaller sensor become part of other comprehensive devices like smart phone or special purpose device like spy planes or missiles.
