In many applications of wireless sensor networks, certain quality of end-to-end parameters is needed. Due to this requirement, supporting quality of service (QoS) in this kind of networks is of great importance. In recent years, multi-path routing technique is proposed as an effective approach to provide QoS. Utilizing multiple paths between senders and receivers, multi-path […]
Recent advances in the field of electronics and wireless telecommunications have created the capability and potential for designing and manufacturing sensors which have low power consumption, small size, reasonable price and various applications. These small sensors, which based on their type, can perform different tasks such as receiving environmental information, processing it and then sending […]
Security is considered to be one of the most important challenges in wireless sensor networks (WSNs). Due to inherent resource constraints in WSNs, traditional security mechanisms may not be used in these networks. In recent years, trust and reputation management in distributed systems has been proposed as a novel and accurate way for handling security […]
The concentration of data transfer towards the sink in a wireless sensor network causes the nearby nodes to exhaust their batteries faster than other nodes, which leaves the sink trapped and disrupts the data reporting by sensor nodes to each other. To avoid such scenarios, protocols with mobile sinks was proposed. It helped in achieving […]
In recent years, Network Coding (NC) has been used to increase performance and efficiency in Wireless Sensor Networks (WSNs). In NC, Sensor Nodes (SNs) of network first store the received data as a packet, then process and combine them and eventually send them. Since the bandwidth of edges between SNs is limited, management and balancing […]
Underwater wireless sensor networks have attracted much attention in various applications such as natural disasters monitoring, defense, industries, etc. A new routing algorithm for underwater wireless sensor networks is developed and tested. The algorithm shows a better end-to-end delay yet less energy consumption. This was achieved by limiting the data transmission to a number of […]
The focus is on the longevity and energy efficiency of wireless sensor networks (WSN). WSNs face many obstacles in terms of data transmission. WSNs face difficulties in reducing energy output and shortening life cycles, including node configuration, leader selection, and optimal routing selection. The provisioning of nodes, selection of cluster leaders, and optimal paths have […]
The research focuses on the foundational elements of the Internet of Things (IoT) infrastructure and its applications in smart buildings, smart parking, and smart cities. Wireless Sensor Networks (WSNs) play a critical role in enabling these applications. However, due to their low battery energy, WSN nodes are severely constrained, limiting their operation to a few […]
