Even if the hype is discounted, it is generally agreed that wireless sensor networks have tremendous growth potential. By its very nature, a wireless link is susceptible to interference that can disrupt normal operation. There are different grades of service disruption from minor annoyance to total breakdown, none of which is an acceptable option for critical applications. There are many techniques to counter RF interference: direct blocking techniques like shielding, grounding and bypassing form the first line of defense. Active counter measures include channel surfing, whereby the sensor nodes adapt their channel assignments to restore network connectivity in the presence of interference. It is important to consider all possible techniques and the type of sensors being used before designing a system for deployment.
