Spontaneous progress in the field of wireless sensor networks (WSN) have led to development of various protocols for reliable communication and increasing longevity of the network. While designing the protocols for WSNs, designers come across the issues like limited energy per node, limited bandwidth for communication, security, minimum communication and computational cost. This paper focuses on energy...
Wireless sensor network (WSN) comprises of several nodes usually called motes or sensors. These motes gathered together and collect data by observing the surroundings and reported the information to one or more reliable links. This valuable data only be accessible between two communicating parties. To secure the data that delivers between the two parties, we require a secure node authentication scheme...
Wireless Sensor Networks (WSNs) is the most developing areas in many factors like environment & wildlife monitoring, security & military surveillance, healthcare and many more. Also, routing protocols play a very important part in terms of efficiency in WSNs. Due to limitations of unreliable low power links and resources between the sensor nodes; design of an efficient routing protocol is...
Wireless Sensor Networks (WSNs) is collection of large number of sensor nodes which are of limited capabilities, to collect sensitive information. With the advancement of this technology, one of the major concerns these days is of security. There are so many attacks possible on WSN, in Distributed-Denial of Service (DDOS) attacks, malicious nodes adapts many attacks such as flooding attack, black...
Wireless sensor networks are principally categorized by insufficient energy resource. Naturally, communication between the nodes is the utmost energy consuming act that they perform. Hence, development of a well-organized clustering algorithm can play a vital part in enhancing the lifetime of network. Currently, nature inspired methodologies are very common in dealing with it. This work presents a...
A Wireless Sensor and Robot Network (WSRN) is composed of a set of sensors and robots. Compared with the traditional Wireless Sensor Network (WSN), the WSRN has added characteristics, such as the mobility of robots. The mobility of robots has been proven to be quite useful in prolonging the network lifetime of the monitoring environment. However, mobility is a major part of the energy consumption...
To perform some operation there is a need of some amount of energy over the node is same to the sending the single bit of data in the network. Data transportation reduces the network lifetime when sending data in sensor network. So the need to reduce the energy consumption for improving the network lifetime. As cluster head is aggregator node of the cluster it can take part in communication many times...
Wireless sensor network will become isolated in various associated segments because of the disappointment of some of its hubs, which is known as a “cut”. In this paper, authors acknowledge the issue of distinguishing cuts by the remaining hubs of a wireless sensor network. System proposes an estimation which grants every hub to identify at the time of accessibility to an extremely assigned hub has...
Compressive sensing (CS) is a promising data acquisition and compression technology that can be used to reduce and balance the transmission cost in wireless sensor networks (WSNs). However, the transmission links are unreliable frequently and data loss is very common in wireless sensor networks. What's more, the reconstruction accuracy is reduced greatly due to unreliable links and data loss. In order...
Sweep coverage is an important problem in wireless sensor networks. With sweep coverage, more Points Of Interests (POIs) can be monitored with fewer mobile sensor nodes thanks to the mobility of the nodes. Most existing studies on sweep coverage focus on the trajectory of the mobile sensor nodes to guarantee the sweep coverage of the POIs. Considering the fact that, in many applications, the collected...
In recent days, wireless sensor networks (WSN) are catching the spotlights in networking and other emerging fields like large data communication, artificial intelligence, automation systems etc. The major constraint wireless sensor networks are struggling with limited energy supply issues for their sensor nodes. This paper is focused to put emphasis on implementing a clustering protocol inspired from...
Wireless Sensor Networks (WSNs) consist of multiple sensors distributed in a certain geographic area. The goal of using WSNs is to monitor certain phenomena such as; environmental or physical. The nodes in WSNs transmit data through a wireless network that lacks infrastructure, which makes those networks exposed to security threats. One of those security threats is the black-hole attack which can...
In wireless sensor networks (WSNs), efficient use of the nodes' available energy is the main goal which most of the routing protocols seek to achieve. In fact, clustering based routing protocols have gained vast approval due to its merit of less energy exhaustion. The expended energy by one cluster is divided into two main terms, namely, the expended energy in intra-cluster communication (Intra-term)...
Wireless sensor network (WSN) is the interconnection of wireless nodes with limited energy and memory. These networks can be deployed for many critical applications like military operations, rescue management, fire detection and so on. In flat routing structure every node plays equal role of sensor and a router. The topology may change very frequently due to the mobile nature of nodes in WSNs. Maintaining...
Speed measurement is an important issue for some types of Wireless Sensor Networks (WSN), especially for Vehicular Ad-hoc Networks (VANETs). However, calculating this value is error-prone and costly. This report intends to demonstrate the calculation of speed of an object without the use of any additional devices or sensor boards, only using Received Signal Strength Indication (RSSI) for localization...
TheStreet lighting systems is one of the greedy consumers of electricity. It represents a financial burden on local authority. Reducing its cost is the purpose of many research projects. The idea presented in this paper, is the development of a street lighting control system based on wireless sensor networks to reduce the power consumption. Our new method is around a control system, where the Street...
Applicability of Wireless Sensor Networks is found in fields manifold. Energy issues proved to be a continuous setback to the performance of these networks.

The local base stations or the cluster heads aggregate data from nearby nodes, process it and...
Wireless Sensor Network (WSN) consisting of a large number of tiny sensor nodes deployed in unattended hostile environment is vulnerable to various attacks including node capture. An attacker may physically capture, reprogram and redeploy a node in the network. A node, that is victim of capture attack, must be revoked from the network to avoid further insider attacks. In this paper, we present a node...
Wireless sensor networks include a set of sensors being network nodes and a base station. The objective of such systems is to monitor changes which might occur at targets' location.
