Secured anonymous data transmission using parser and bi-variate pascal value for wireless sensor networks [articol]

Abstract

A large scale Wireless Sensor Network (WSN) consists of numerous sensor nodes that may disperse over a wide-ranging zone. Sensor nodes are deployed for various applications. However, it is difficult to protect and monitor the nodes continuously for large scale sensor networks. Also providing security measures for each and every individual node in the network is a critical task. Anonymous Secured Data Transmission (ASDT) scheme is proposed here to hide the identities of nodes and to isolate the malicious node from the network. The main objective of the work is to detect the malicious node and to protect the data from the attackers. To identify the adversary nodes and to isolate them from the data transmission route Bottom-up parser approach is used. For secured transmission of data Bi-varitae Pascal value (BPV) method is considered. This generates a duplication route in which the source node, destination node, and intermediate nodes does not reveal their original node ID’s and data ID’s. Therefore secured and confidential information’s can be passed over the nodes even in the presence of adversary nodes during routing. The simulation is carried out using NS2 simulator tool. The simulation parameters such as packet delivery ratio, lost ratio, throughput, delay and false node detection ratio are evaluated.
