Trust based energy efficient detection and avoidance of black hole attack to ensure secure routing in MANET

In this paper, we propose a solution for detecting and avoiding black hole attacks (both single and cooperative) and ensuring secure packet transmission along with efficient resource utilization of mobile hosts at the same time. According to our proposal, evaluation of trust of every node in the network is based on parameters such as stability of a node defined by its mobility and pause time, remaining battery power etc. This trust of a node forms the basis of selection of the most reliable route for transmission. The simulation results show that our solution provides good performance in terms of throughput, secure routing, and efficient resource utilization.
