Wireless sensor network comprises of scattered sensors to sense, monitor and aggregate the sensed information. The major issue in a wireless sensor network is to balance network load and to maintain less energy consumption where multi parent crossover method is considered. Multiparent cross over method will generate offspring from parent and aims at managing the load. In this paper a comparative study of different algorithms is done where the load balancing and energy consumption issue has been resolved.

Recently, heterogeneous wireless sensor network (HWSN) routing protocols have drawn more and more attention. Various HWSN routing protocols have been proposed to improve the performance of HWSNs. Among these protocols, hierarchical HWSN routing protocols can improve the performance of the network significantly. In this paper, we will evaluate three hierarchical HWSN protocols proposed recently—EDFCM, MCR, and EEPCA—together with two previous classical routing protocols—LEACH and SEP. We mainly focus on the round of the first node dies (also called the stable period) and the number of packets sent to sink, which is an important aspect to evaluate the monitoring ability of a protocol. We conduct a lot of experiments and simulations on Matlab to analyze the performance of the five routing protocols.

With the increasing number of vehicles, the management of parking spaces in cities is becoming increasingly important in improving the quality of life and combating air pollution. Indeed, finding a parking space at peak times and in congested areas of the population becomes a huge challenge for drivers. To remedy this problem, most modern cities have smart parking. The equipment of these smart parking is mainly based on the implementation of wireless sensor networks (WSN) to monitor, track, and collect real-time information on the occupancy status of each parking space. This information is then made available to drivers who are looking for an available parking space. However, sensor nodes have limitations in terms of energy and communication that affect the performance and quality of the wireless sensor network. Therefore, the design of a self-organization protocol for WSN that minimizes power consumption and maximizes the longevity of the WSN network must be taken into account when implementing and developing a sustainable and viable intelligent parking system. In this paper, we propose a protocol for self-organization of wireless sensor networks (WSN) for the management of parking spaces in outdoor and urban car parks. This protocol is based on building clusters using ZigBee transmission technology for multihop communication. Each sensor node will be installed in the ground of each parking space to monitor its availability by sending the empty or busy state of that space to the gateway using cluster head nodes (CHs). This approach has a robust and efficient self-organizing algorithm that minimizes energy dissipation and increases the lifetime of sensor nodes and the WSN network. The simulation results show that parking management systems in outdoor and urban car parks using the self-organization protocol presented are efficient and sustainable in terms of energy consumption, reliability of data transmission, and the longevity of the WSN network compared to other existing parking systems that use different self-organizing protocols for wireless sensor networks.

Для мониторинга состояния лесов и лесных пожаров принято использовать различные технические наземные, авиационные и космические средства. Однако применение данных средств часто затрудняется отсутствием в лесу доступа к источникам электропитания и информационным сетям. Единственной на сегодняшний день технологией, позволяющей успешно решать задачи мониторинга состояния лесов и лесных пожаров, обеспечивающей длительное использование системы без необходимости замены ее устройств из-за отсутствия энергообеспечения и их технического обслуживания непосредственно в местах развертывания сети, является технология беспроводных сенсорных сетей. Беспроводная сенсорная сеть - это совокупность миниатюрных необслуживаемых распределенных в пространстве вычислительных устройств, которые снабжены сенсорами и приемопередатчиками сигналов, работающих в радиодиапазоне и образующих самоорганизующуюся систему сбора, обработки и передачи информации. Применимо к мониторингу лесов наиболее подходящей топологией беспроводной сенсорной сети является ячеистая топология, в которой все сенсоры обладают функциями маршрутизации. Маршрутизация позволяет обеспечить возможность самовосстановления сетей в случае выхода из строя некоторых сенсоров при лесных пожарах или других негативных воздействиях, что позволяет достаточно быстро переформировать сеть с новой конфигурацией. Информация, собираемая сетью, передается на шлюз, который выполняет координирующие функции по организации работы беспроводной сенсорной сети, и связан с корпоративной сетью с помощью проводной или беспроводной связи. Благодаря способности узлов ретранслировать сообщения, обеспечивается значительная площадь покрытия территории даже при малой мощности передатчиков, поскольку информация передается от одних сенсоров к другим по цепочке, и в итоге ближайшие к узлу сенсоры сбрасывают ему всю аккумулированную информацию. Предлагается использовать геоинформационные технологии, обеспечивающие разработку специализированных решений для визуализации и анализа данных, что позволит пользователю осуществлять оперативный мониторинг лесных территорий и прогнозировать неблагоприятные воздействия, в том числе лесные пожары. Данная информационная система мониторинга лесов и лесных пожаров с использованием беспроводных сенсорных сетей эффективно и с малыми затратами обеспечивает решение задач контроля труднодоступных лесных территорий, устойчива к отказу отдельных узлов по различным причинам, что позволяет использовать и эксплуатировать сеть на лесных территориях с различными ландшафтными, таксационными и антропогенными параметрами. Monitoring of the state of forests and wildfires is common to use a variety of technical ground, air and space assets. However, using these funds is often hampered by lack of access to sources of electricity supply and information networks. The only technology solution of the problem of monitoring forests and wildfires, which provides long-term use of the system without having to change its device due to lack of energy and maintenance directly in the field of network deployment is a wireless sensor networks. Wireless sensor network - a set of miniature independent distributed computing devices, which are equipped with sensors and transceivers operating in the radio range and forming a self-organizing system of collecting, processing and transmitting information. Applicable to the monitoring of forests the most appropriate topology of wireless sensor network is a mesh topology in which all sensors have routing functions. Routing provides the possibility of self-healing network in case of failure of some sensors in case of wildfires or other negative influences that allows one to quickly rebuild the network with the new configuration. The information collected by the network is transmitted to the gateway, which performs coordinating functions related to the organization of a wireless sensor network and is connected to the corporate network via a wired or wireless connection. The ability of nodes to relay messages provides significant area coverage area, even at low power transmitters, because the information is transferred from one sensor to another, and finally coming to a gateway sensor and dump all accumulated information. We suggested to use GIS technology to ensure the development of specialized solutions for the visualization and analysis of data, allowing the user to perform real-time monitoring of forest areas and to predict hazards. The information system of forest and wildfires monitoring with the use of wireless sensor networks efficiently and at low cost provides a solution to control tasks for inaccessible forest areas and can be resistant to failure of individual nodes, for various reasons, so it can be used to operate the network in forest areas with different landscape, biometrical and anthropogenic parameters.

The success of the mission assigned to a Wireless Sensor Network (WSN) depends heavily on the cooperation between the nodes of this network. Indeed, given the vulnerability of wireless sensor networks to attack, some entities may engage in malicious behavior aimed at undermining the proper functioning of the network. As a result, the selection of reliable nodes for task execution becomes a necessity for the network. To improve the cooperation and security of wireless sensor networks, the use of Trust Management Systems (TMS) is increasingly recommended due to their low resource consumption. The various existing trust management systems differ in their methods of estimating trust value. The existing ones are very rigid and not very accurate. In this paper, we propose a robust and accurate method (RATES) to compute direct and indirect trust between the network nodes. In RATES model, to compute the direct trust, we improve the Bayesian formula by applying the chaining of trust values, a local reward, a local penalty and a flexible global penalty based on the variation of successful interactions, failures and misbehaviors frequency. RATES thus manages to obtain a direct trust value that is accurate and representative of the node behavior in the network. In addition, we introduce the establishment of a simple confidence interval to filter out biased recommendations sent by malicious nodes to disrupt the estimation of a node's indirect trust. Mathematical theoretical analysis and evaluation of the simulation results show the best performance of our approach for detecting on-off attacks, bad-mouthing attacks and persistent attacks compared to the other existing approaches.
