And Performance

Wireless Sensor Networks are widely used nowadays to support the decision-makers in different applications by monitoring and collecting the environmental parameters in specific areas. Sensors are deployed in such areas either randomly or formally. In a high-density Wireless Sensor Network, several sensors are randomly deployed in a small area. This will make the adjacent sensors collect same data and send them to the sink, which will increase the power consumption in those sensors. Adjacent sensors are considered critical because of their effect on the network performance. In this paper, the effect of the adjacent sensors is minimized because of the above-mentioned criticality and performance influence of these sensors. The proposed mechanism is evaluated by using MATLAB simulator and is then compared with the low-energy adaptive clustering hierarchy (LEACH) protocol. Results prove that the proposed mechanism outperforms the LEACH protocol by 21% in terms of the network lifetime and by 18% in terms of the number of the transmitted packets to the cluster heads and reduces the number of the transmitted packets to the base station by approximately 3% by avoiding the duplicated packets.

Network layer functionalists are of core importance in the communication process and so the routing with energy aware trait is indispensable for improved network performance and increased network lifetime. Designing of protocol at this under discussion layer must consider the aforementioned factors especially for energy aware routing process. In wireless sensor networks there may be hundreds or thousands of sensor nodes communicating with each other and with the base station, which consumes more energy in exchanging data and information with the additive issues of unbalanced load and intolerable faults. Two main types of network architectures for sensed data dissemination from source to destination exist in the literature; Flat network architecture, clustered network architecture. In flat architecture based networks, uniformity can be seen since all the network nodes work in a same mode and generally do not have any distinguished role.

Wireless sensor networks consist of hundreds or thousands of sensor nodes that involve numerous restrictions including computation capability and battery capacity. In this paper we propose an optimal algorithm with genetic algorithm taken into consideration, and compare it with three well known and widely used approaches, i.e., LEACH and LEACH-C, in performance evaluation. Experimental results show that the proposed approach increases the overall network lifetime, and data delivery at the base station than the other routing protocols.

The zone of wireless sensor networks (WSNs) is one of the developing and quickly developing fields in the logical world. This has realized growing ease, low-control and multiwork sensor hubs. Nonetheless, the real certainty that sensor hubs come up short on vitality rapidly has been an issue and numerous vitality effective directing conventions have been proposed to take care of this issue and safeguard the life span of the network. The proposed EEDBLEACH chooses bunch head with most elevated leftover vitality in every communication round of transmission and furthermore considers, the briefest good ways from the base station to the hubs in the group. By accepting the separation as a parameter which diminishes the vitality utilization. The EEDBLEACH Protocol is correlation with the current LEACH convention.

Encryption Method

In this paper, elliptic curves Diffie Hellman-Rivest Shamir Adleman algorithm (ECDH-RSA) is a novel encryption method was proposed, which based on ECDH and RSA algorithm to secure transmitted data in heterogeneous wireless sensor networks (HWSNs). The proposed encryption is built under cheesboard clustering routing method (CCRM). The CCRM used to regulate energy consumption of the nodes. To achieve good scalability and performance by using limited powerful max-end sensors besides a large powerful of min-end sensors. ECDH is used for the sharing of public and private keys because of its ability to provide small key size high protection. The proposed authentication key is generated by merging it with the reference number of the node, and distance to its cluster head (CH). Decreasing the energy intake of CHs, RSA encryption allows CH to compile the tha data which encrypted with no need to decrypt it. The results of the simulation show that the approach could maximize the life of the network by nearly (47%, and 35.7%) compare by secure low-energy adaptive clustering hierarchy (Sec-LEACH and SL-LEACH) approches respectively.

Selfish Herd

Clustering achieves energy efficiency and scalable performance in wireless sensor networks (WSNs). A cluster is formed of several sensor nodes, one of them selected as the cluster head (CH). A CH collects information from the cluster members and sends aggregated data to the base station or another CH. In such a hierarchical WSN, some nodes are possibly moveable or nomadic (relocated periodically), while others are static. The mobility of sensor nodes can improve network performance and prolong network lifetime. This paper presents the idea of mobile, solar-powered CHs that relocate themselves inside clusters in such a way that the total energy consumption in the network is reduced and the network lifetime is extended. The positioning of CHs is made in each round based on a selfish herd hypothesis, where the leader retreats to the center of gravity. Based on this idea, the CH-active algorithm is proposed in this study. Simulation results show that this algorithm has benefits in terms of network lifetime and in the prolongation of the duration of network stability period.

The technology revolution in wireless communications and micro-electro-mechanical systems (MEMS) directly affects the development of wireless sensor networks (WSNs), which are used in several application areas, including the military, home, and environment. One of the best categories of routing networks in WSNs are hierarchical protocols (cluster-based). The wellknown protocols in this category include the Low Energy Adaptive Clustering Hierarchy (LEACH). However, the LEACH is vulnerable to many attacks. To provide cryptographic protection against outsider attacks, a modified version of LEACH, called Enhancing Secure LEACH (MS-LEACH) protocol, is used. MS-LEACH enhances security but increases power consumption. To maintain an acceptable level of security and decrease the power consumption of secure LEACH protocols, the present research proposes a Secure Lightweight LEACH (SLWLEACH) scheme. The simulation results show that this proposed SLW-LEACH protocol outperforms the MS-LEACH in terms of ne

<span>Recent days witnessed considerable developments in the field of wireless sensor networks (WSNs). The applications of these networks can be seen in the simple consumer electronic devices as well as in the advanced space technology. The communication protocols are of prior importance and interest; the low-energy adaptive clustering hierarchy (LEACH) protocol is used to enhance the performance of power consumption for the WSNs nodes. The efficiency of a wireless network can be affected by different factors, such as the size of the WSN and the initial energy of the sensor node. This can inspire the researchers to develop the optimum structure of the WSNs to get its desired functionality. In this paper, the performance of the low-energy adaptive clustering hierarchy (LEACH) protocol is investigated using MATLAB to study the effect of the initial energy of the sensor node and the WSN size on the number of the running nodes. It is found that increasing the initial energy of a sensor node increases the life time of the node and hence the number of the running nodes. It has been also approved that the WSN size has an inverse proportion with the number of running sensor nodes during the use of LEACH protocol.</span>

Wireless Sensor Networks is a novel technology of information acquisition and processing. It integrates the technologies of sensor, wireless communication, and microelectronics. It can sense and collect environmental parameters in the range of the network, and then process the parameters cooperatively in real time. We discuss the design principle and performance evaluation method of the data fusion algorithm for wireless sensor networks in detail. We introduce the concept of fusion cost, and emphasize that the data fusion algorithm in wireless sensor networks must be combined with specific application background. Finally, we emphasize the proposed algorithm which combined reduced-rank filtering with adaptive weighted. The fact that it can effectively eliminate the effect of abnormal noise on fusion performance is illustrated through examples. The results showed that this algorithm occupies obviously the advantage in the aspect of fault-tolerant ability.
