Wireless Sensor Network (WSN) is an infrastructureless network with large number of sensing nodes that can monitor areas such as physical or environmental conditions (i.e., temperature, sound, pressure) to collect and report data to the Base Station (BS). Networks face several challenges like energy, and power. Since the sensor nodes are not battery replaceable, the limited energy resource is a main challenge in facing security for WSNs. Hence, network lifetime becomes a major criteria and can be improved by energy efficient routing and secure energy efficient routing for WSN. Routing protocols that provides an effective design in data gathering are energy efficient cluster-based routing protocols. The existing approach (EE-LEACH) provides a WSN with less energy consumption. However, it concentrates mainly in energy resource, but lacks in providing security resources to the network. This paper presents a proposed Energy Efficient LEACH protocol using lightweight secure LEACH (LS_LEACH), where a broadcast authentication algorithm is integrated to produce authenticity. Moreover, the experimental results show the development of proposed EE_LEACH protocol and existing protocol in terms of system throughput, energy consumption and network lifetime. It is obviously shown that the proposed method will provide better network performance and improves the network lifetime.
Wireless Sensor Network is one of the vast areas of research for scholars. In this, energy consumption is a major problem and various protocols are applied till date to reduce it. The main purpose of this paper is to study some of the protocols such as direct transmission, MTE and LEACH. Nowadays, LEACH is a focused area to gain better results. So much research has already been done in this field, but still a lot more can be done to improve the overall performance. After analyzing all these, the authors have tried to decrease the power consumption of WSN using LEACH protocol. The experimental results show that there is an improvement in all parameter terms and more rounds have been energized when compared to basic LEACH. Simulation of the improved LEACH has been carried out on MATLAB and results have been verified and compared with parameters such as dead nodes, alive nodes, sending packets to Cluster Head or base station, etc.
Wireless Sensor Network is a self configurable network with densely deployed sensor nodes. These sensor nodes cooperatively communicate each other and monitor the conditions of the physical environment and is restricted to bandwidth, memory, energy, etc. In Wireless Sensor Network, when an event is detected, the node senses and become active in gathering and data transmission, which cause congestion and results in a large number of packet drops, low throughputs, high energy consumption with a significant amount of wasted energy due to retransmission and increased delay. This paper presents the congestion prediction using probabilistic methods and congestion control using rate control. The rate controlling methods uses the allocation of rate mechanisms are namely rate regulation, rate reduction and split protocol to minimize packet drops, energy consumption of nodes and improve queue utilization, throughput. Each and every method has its own advantages and disadvantages. The SP has a limitation of packet delay while considering the neighbor nodes. To overcome the limitation, a route weight assignment method is proposed. The proposed method is implementing by using Ns2.
Wireless Sensor Network is the application of ad-hoc network. Wireless Sensor Network has several nodes which consists of mobility and more than one base stations. Wireless Sensor Network having a dynamic nature. Mobility of sensor nodes is a challenging task in the networks. Data distribution to a mobile sink is more difficult than to rest of the nodes in the sensor network. If the path is failed, then another route should be selected which is the shortest and best route for efficient data delivery. In the existing work, virtual grid dynamic route adjustment scheme deals with the selection of best path whenever the path fails. It reduces the cost of the selected path by selecting the required hops. In the proposed work, Distance enhanced grid routing algorithm is used to select the new path by selecting the limited number of hops than the existing method. Here, the authors have been providing security from attacker by using asymmetric cryptographic algorithm for efficient data delivery in a shortest distance.
Wireless Sensor Networks are composed of innumerable little accuse, low control devices with sense, local processing and wireless communication capabilities. Minimizing energy expenditure and maximizing the networks natural life are considerable issues in the devise of routing protocol for sensor networks. In this paper, the author has analyzed the competence of LEACH protocol in extending the subsistence for energy-constrained Wireless Sensor Networks. Based on LEACH protocol, a new text of LEACH protocol distance based leach protocol that is to be energy consumption protocol in Wireless Sensor Network is surveyed.
