Abstract

Objectives: This paper presents Secure Authentication Framework Design and Routing Metric based Communication in Multi-hop WMNs (SAF&RM). Methods/Statistical Analysis: In this paper, we use the PKC based pseudonyms that builds secure authentication framework with conditional privacy and Probabilistic Transmission Count (PTC) routing metric for improving reliable communications in WMN. Findings: The combination of MAC-layer retransmission-based reliability and link quality awareness effects are captured for designing the PTC. Applications/Improvements: This approach aims to diminish the sum of overall forwarding nodes in the routing and reduce the bandwidth consumption of the network which ensure high end-to-end packet delivery rate and improve the secure transmission in WMN.

Abstract

Objectives: Wireless Sensor Network (WSN) contains several distributed sensor nodes. Those nodes are limited in power. Recharging the battery of the sensor node is considered to be a difficult task. The key intent of this paper is to achieve better energy efficiency in WSNs. Methods/Analysis: In this paper, an Energy Efficient Cluster Head selection and Data Convening (EECHDC) is proposed in WSNs. Cluster Head (CH) selection is based on residual energy, connection density, capability of the node and degree of the node. Findings: The EECHDC scheme has proved better performance in terms of packet delivery rate, packet loss rate, delay, throughput and residual energy during data transmission. Application/Improvements: Simulation results show that the EECHDC achieves higher energy efficiency compared to the existing schemes.

Abstract

Objectives: Due to restricted computational power and energy resources, aggregation of data from multiple Sensor Nodes (SNs) secure routing is a significant problem because of highly susceptible in WSNs (Wireless Sensor Networks). Hence ascertaining trustworthiness of data is vital for WSNs. Group-based Trust Management Scheme (GTMS) introduced the trust that depends on direct and indirect monitoring. However, it consumes more energy to communicate the data transmission in WSNs. The main objective of this paper is to transmit the data through the trust node and secure data transmission in WSNs. Methods: The cluster head plays an important role in the cluster-based network. In this paper, we propose Design of Hierarchical Trust based Efficient Cluster Head Selection in WSN (HTECH) which demonstrates the Cluster Head (CH) selection process based on Trust based routing in WSN. This trust is evaluated based on node cooperativeness, Unselfishness, honest and data transmission rate. Findings: The trust evaluation is used to avoid the malicious and selfish node present in the routing path. Thus, this method provides a realistic and secure approach to choose a shortest path in all trusted path. The simulation results shows that the HTECH scheme reduce both packet loss rate, delay, and improve the throughput in WSNs. Improvements: The HTECH trust routing remove the untrustworthy nodes in order to obtain a reliable passage delivery route also reduce the energy consumption when compared to the existing method.
