An Enhance Approach to Mitigate the Impact of Black Hole and Gray Hole Attacks in AODV Routing Protocol
Abstract: Wireless network has become more and more popular during the past decades. A mobile ad hoc network (MANET) is integrating of mobile nodes, in which the packets are forwarded without any centralized network authority. The devices are connected via wireless medium. Due to this, characteristic security is high risk because packets are easily trapped in the network. There is no pledge of attack free communication due to heterogeneity in the …

Improved Performance by Using k-means Clustering in Vehicular Ad Hoc Network
Abstract: AbstractVANETs are formed by applying the principles of MANETs, in which all node, i.e., vehicles can pursue traffic law with high speed. VANETs support two types of communication: vehicle - to- vehicle (V2V) and vehicle to-infrastructure (V2I). Vehicles communicate to RSU for the exchange of keys for the security purpose and RSU communicate to Authentication Server (AS) for the formation of secret keys. But in existing work they perform nonsymmetric …

Power and Congestion Control for M.A.N.E.T using Cross-Layer Design for Future Technology
Abstract: AbstractRouting in M.A.N.E.T is challenging due to its navigation feature. The main causes of link failure are mobility, interference, and congestion. Mobility means that each node is free to move within its transport range. Interference occurs due to collision and hidden node. A hidden node means two nodes outside the radio range of each, simultaneously try to transfer data to an intermediate node, which lies in the radio range of …
