An ad-hoc network is a multi-hop wireless network where all nodes cooperatively maintain network connectivity without a centralized infrastructure. If these nodes change their positions dynamically, it is called a Mobile Ad-hoc NETwork (MANET). The security of ad hoc networks is becoming an increasingly complex issue. Security requirements such as authentication, non-repudiation, data integrity and confidentiality, which would otherwise be provided by a central server, must be enabled and provided by all nodes. In this paper, the authors proposed enhance based direction routing protocol. The zone direction is reduced until the node can select the strongest and most stable link and so increase availability in the network.
