MANET: Security Aspects and Challenges
There has been a huge advancement in the field of wireless networks in last few decades. It gives new direction in the field of internet with its large number of applications. A mobile ad hoc network or MANET is self-configuring infrastructure less network of mobile device (laptops, Smartphones, sensors, etc.) connects by wireless link. This type of network is standalone network. Security is a primary issue in order to provide secure communication in hostile environment. There are still some challenges associated with MANETS that needs to be overcome. These challenges include routing, short battery life, limited capacity, dynamically change topology, etc.
