Wireless ad hoc network is a network where there is no existence of wireless infrastructure for networking. Thus this kind of network have limited homogenous feature. In sensor networks, building efficient and scalable protocols is a very challenging task due to the limited resources and the high scale and dynamics uses the GRA (Geographic Routing Algorithm) to get this location information. With the availability of GRA, the mobile hosts knows there physical location. One main challenge in design of these networks is their vulnerability to security attacks. The authors identify the new challenges and opportunities posed by this new networking environment and explore new approaches to secure its communication.
