A New Protocol for Detecting Black Hole Nodes in Ad Hoc Networks

Abstract: An ad hoc network is a collection of infrastructureless nodes, cooperating dynamically to form a temporary network which meets certain immediate needs. The lack of infrastructure implies that the nodes are connected peer-to-peer. Therefore, each node acts as a router beside its main role as a host. With the increased number of mobile devices, the applications of ad hoc network increased dramatically to capture different domains such as: academic communication, and mobile conferencing beside its traditional domains such as: military communication, and emergency communication. Security issues become more challenging in ad hoc network due to its dynamic nature which allows any node to freely join as well as leave the network without having a physical address or getting permission. Ad hoc networks are vulnerable to different kinds of attacks such as: denial of services, impersonation, an
