Secure Data Transmission

This paper proposes energy efficient LEACH protocol for secure data transmission for wireless networks. The proposed work uses Networks Simulator – NS2.27 for the simulation of cluster based routing protocol LEACH in wireless sensor network. The work is to enhance the performance of LEACH in terms of energy saving and secure data transmission. Instead of random selection of Cluster Head (CH) the selection method is based on residual energy and vicinity of the node. With this hybrid approach, the node, which is eligible for the CH, will become cluster head and it enhances the performance of traditional LEACH. Traditional LAECH does not support secure data transmission and authentication of nodes in the clusters. By adding security between CH and CM using XOR function and key management, secure data transmission and authentication is carried out for selected application where security is the most important aspect. The proposed LEACH enhances lifetime of the wireless sensor network with security.

Fuzzy C Means Clustering

Wireless Sensor Network (WSN) is developed extremely because of their low installation cost and various applications. WSN has compact and inexpensive sensor nodes for monitoring the physical environment. WSNs are susceptible to many attacks (e.g. malicious nodes) because of its distinct characteristics. The performance of node and network is affected by the malicious nodes. Moreover, the communication among the sensor nodes also required to be secured for preventing the data from the hackers. In this paper, the architecture of the WSN is generated by using the Fuzzy-C-Means clustering (FCM). Then the detection of the malicious nodes is performed by using the Acknowledgement Scheme (AS). This AS is integrated in the Ant Colony Optimization (ACO) based routing for avoiding the malicious nodes while generating the route from the source to the Base Station (BS). Then the Hybrid Encryption Algorithm (HEA) is used for performing the secure data transmission through the network and this proposed method is named as HEA-AS. The performance of the HEA-AS method is evaluated in terms of End to End Delay (EED), network lifetime, throughput, Packet Delivery Ratio (PDR) and Packet Loss Ratio (PLR). The proposed HEA-AS method is compared with the existing method called as CTCM to evaluate the effectiveness of the HEA-AS method.

Secure Data Transmission

The wireless sensor network is a type of ad hoc network which is vulnerable to security attacks, specifically insider attacks. In spite of the fact that confidentiality, integrity and authentication helps in forestalling the particular sort of attacks, but they come at an expense. A traditional and evergreen concept of the trust evaluation and management, among the nodes of a network, for communication is a good and effective security measure. Overseeing trust in a distributed wireless sensor network is a challenging task when coordinated effort or participation is must in accomplishing mission and framework objectives. The paper represents a survey of various trust applications which are very helpful for carrying out a secure data transmission in a sensor network. The analysed trust applications malicious attack detection, secure data aggregation, secure node selection and secure routing.
