Secured link quality, delay and energy aware routing protocol (SLQDEARP) for mobile Ad Hoc networks

Routing Optimization in mobile ad hoc networks along with secured transmission is an ever-demanding task. Mobile ad hoc networks are highly dynamic topology natured and hence several routing protocols meet the challenge of link quality, delay and energy conscious routing. This paper proposes a secured link quality, delay and energy conscious routing approach based on ant colony optimization. Based on the estimated link quality, delay and residual energy of the nearby nodes, Adaptive node stability (ANS) mechanism is mathematically modeled to make the routing strategy. SLQDEARP selects the efficient node based on the ANS mechanism and sends the data packets through that node. Ad-hoc security algorithms incorporated for making the transmission more secured. Simulation results show that SLQDEARP increases delay, energy consumption and packet delivery ratio than AODV and DECRP protocol due to security mechanism incorporated.
