Abstract
An ad hoc network is a temporary network for a specified work. Even after ensuring security, there are many other security threats that resist its growth and uses. Modern mobile gadgets are capable of creating economical, reliable, dynamic and self configuring networks but their main capabilities SAAS, PAAS, IAAS and wireless communication are being exploited and resisted by Ad Hoc Networks. The major issue with these networks is the security and that is what is exploited by the modern industry and determines its level of security and makes it easier to attack. The main aim of this research is to understand the core elements of Ad Hoc Networks and its routing protocols before, during and after network attacks. Black hole is one of the most serious issue with this network as well and in this research article we will discuss how to make it more reliable and more attack resistant network.
