Publication Date : 08/10/2019
Physical layer security is a justifiable method which is possible with the current cryptographic techniques to battle security assaults in wireless networks. The open communications surroundings make Mobile Ad-hoc Networks transmissions greater susceptible to eavesdropping attack. Therefore, this paper proposes a developed Modified Physical Layer Security Routing protocol, referred to as MPLSR. The Proposed MPLSR contributions are: First of all, MPLSR reflects a cross-layer technique that uses both physical layer and network layer information collectively to support Quality of Service transmissions. While a routing route is set up, both the physical layer data, (distance among intermediate node and eavesdropper node), and the network layer data, (number of multi hops) are the factors used collectively to establish a route. Secondly, MPLSR establish routing routes away from eavesdropper node overhearing range to guide secure transmission. Thirdly, MPLSR protocol gives a better performance in phrases of Security, End to end delay, Packet Delivery Ratio, throughput and overhead in terms of network speed. Simulations results showed that our protocol offers a better delay performance of 59 milliseconds while PLSR exhibited a longest delay of 65.1 milliseconds. Also, the PDR of PLSR deteriorates from about 0.9 to 0.67 representing 25% degradation, our protocols suffers only 12% deterioration. The overall performance assessment of MPLSR using Optimized Network Engineering Tool (OPNET) Software shows that MPLSR provide a solution to cover both the performance and security problem in a multi hop transmission of a MANET.
