Energy consumption evaluation in trust and reputation models for Wireless Sensor Networks

In this paper, popular trust and reputation models for Wireless Sensor Networks (WSNs) is studied. Accuracy, scalability and power consumption are the main challenges during the routing of data. High power consumption reduces network lifetime. Due to the lack in researches that compare between trust and reputation models especially in terms of energy efficiency this paper presents comparison between several proposed trust and reputation models in terms of average path length, average accuracy and energy consumption rate.

Improving the Lifetime of Wireless Sensor Networks Based on Routing Power Factors

In this paper the power efficiency of Wireless Sensor Networks (WSNs) Power is studied. Power consumption is the main challenge during the routing of data. The objective of this study is to address three routing parameters that affect the network life time such as initial power of the nodes, the residual power in the nodes and routing period. Simulations of the effects of these parameters are presented in different network sizes. Contribution on how to improve network lifetime through consideration of power consumption factors during routing is added.

Comparison between RSA hardware and software implementation for WSNs security schemes

The need of security to protect the data through networks has become of vital importance and critical for many sensor network applications. There are several security schemes implemented using hardware or software trying to solve the problem of security in WSN by taking into consideration the limitations of sensors (bandwidth and energy), the majority of them are symmetric key encryption schemes and some others are asymmetric encryption schemes is not recommended to be used because of high time complexity and consumption demand. In this study we compare the time complexity and power consumption between software and hardware implementation using RSA algorithm. Our simulation shows that usage of hardware security could improve time efficiency and decrease the power consumption, so the strong cryptography can be implemented in WSNs security.

Energy-Distance Aware Clustering Scheme (E-DACS) for Wireless Sensor Networks

In this paper, popular clustering protocols for Wireless Sensor Networks (WSNs) are investigated. There are many issues and challenges that effect network lifetime. One of these critical issues is high power consumption which reduces network lifetime. The aim of this paper is to propose Energy-Distance Aware Clustering (E-DACS) approach that considers sensor energy level and distance during cluster heads selection to increase the throughput. In this method, cluster head selected among other nodes in the cluster by optimal criteria that calculate the distance to each node, distance to base station, and residual energy. Performance, network efficiency and maximizing network lifetime are measured by simulation, analysis and comparison with other well-known mechanisms.

Residual Energy Effects on Wireless Sensor Networks (REE-WSN)

This study presents the effect of residual energy of nodes in Wireless Sensor Networks (WSNs). There are many issues and challenges that still need to be solved in this area especially for energy contrain. This factor considered during clustering and routing approached to maximize network lifetime. To prolong network lifetime, there is a need for efficient power control mechanisms to reduce power consumption in sensor nodes. At the same time, energy efficient techniques should be employed at all layers of the network. This paper proposed an approach for WSNs energy conservation in order to maximize network lifetime by investigating Residual Energy Effects on Wireless Sensor Networks (REE-WSN). The performance and efficiency of REE-WSA are measured through simulation results and analysis.

Hybrid Solution for Secured and Energy Aware Routing Path in Wireless Sensor Networks

Recently, Wireless Sensor Networks (WSNs) and its applications have obtained considerable momentum due to its growing usage in different applications. However, security and power limits of WSNs are still important matters especially during routing since the early beginning of this research due to few of previous studies take into consideration security threats and energy consumption at the same time. Many existing approaches at most concentrate on cryptography to improve data security but this addresses only a part of the security problem without consideration for high energy consumption. This article presents a hybrid solution that depends on combination between network nodes trustworthiness and energy aware routing mechanism. This solution provides security and minimizes power consumption during routing. Performance and efficiency are measured through simulation results, analysis and comparison with well-known mechanisms.
