Improving the robustness and security in a real time and scale free wireless sensor network

Abstract

The development of the Wireless sensor networks (WSNs) in the newlinerecent years is mainly due to the readily obtainable low cost and short-range newlinesensors. The objective of the WSN system is to both sense and transmit the newlinereal-time sense contents belonging to a particular monitoring environment for newlinethe back-end system for performing the necessary processing and analysis newlinetasks. One of the most significant tasks of prime consideration is to ensure the newlinesafety and privacy aspects of the WSN in a wireless channel. The ultimate newlineidea of the Wireless Sensor Network is to preserve the limited node energy newlineand thereby process the huge volume of data without affecting the robustness. newlineThe main objective of this work is to strengthen the robustness of newlinethe Wireless Sensor Network that particularly relies on a scale-free type of newlinenetwork. The ability of the Scale-free WSNs in tolerating the random attacks newlineefficiently have made them appear significant; on the other hand, they may be newlinevulnerable to certain malicious attacks, that specifically targets the significant newlinenodes in the system. This limitation has been addressed in this work by means newlineof introducing a new modelling strategy called SPRT (Sequential Probability newlineRatio Test) that assists in the generation of scale-free network topologies. newlineSPRT, a unique robustness improvising algorithm for the scale free type of newlineWSNs, has been designed in this work and also the proposed SPRT is newlinecompared with the existing EROSE technique. newlineWireless Sensor Networks (WSN) has been applied for collecting newlinedata regarding the physical parameters in diverse application areas. As a newlinepromising technology it brings about a faster development in the area of newlineadvanced wireless telecommunication. newline
