Energy is an important consideration in the design and deployment of wireless sensor networks (WSNs) since sensor nodes are typically powered by batteries with limited capacity. Since the communication unit on a wireless sensor node is the major power consumer, data compression is one of possible techniques that can help reduce the amount of data exchanged between wireless sensor nodes resultin...

Wireless Sensor Networks (WSNs) offer inherent packet redundancy since each point within the network area is covered by more than one sensor node. This phenomenon, which is known as sensors co-coverage, is used in this paper to detect unauthenticated events. Unauthenticated event broadcasting in a WSN imposes network congestion, worsens the packet loss rate, and increases the network energy con...

Increased demand for Wireless Sensor Networks(WSNs) in fields such as the military, ecological survey and health related areas which deals with sensitive information has imposed the overhead of security in such networks. Attacks on wireless sensor networks have justified the importance of security in this field. Constraints on memory, computation, energy and transmission range associated with W...

In wireless sensor networks (WSNs), energy source is usually battery cell, which is impossible to recharge while WSNs are working. Therefore, one of the main issues in wireless sensor networks is how to prolong the network lifetime of WSNs with certain energy source as well as how to maintain coverage and connectivity. In this paper, we consider the wireless sensor networks satisfying that each...

Wireless sensor nodes are small, embedded computing devices that interface with sensors/ actuators and communicate using short-range wireless transmitters. Such nodes act autonomously, but cooperatively to form a logical network, in which data packets are routed hop-by-hop towards management nodes, typically called sinks or base stations. A Wireless Sensor Network (WSN) comprises of a potential...

Intermittently Connected Delay-TolerantWireless Sensor Networks (ICDT-WSNs), a branch of Wireless Sensor Networks (WSNs), have features of WSNs and the intermittent connectivity of Delay-Tolerant Networks (DTNs). The applications of ICDT-WSNs are increasing in recent years, however, the communication protocols suitable for this category of networks often fall short. Most of the existing communi...

The rapid advancement of digital electronics and wireless communications has resulted in more rapid development of Wireless Sensor Networks (WSN) technology. In the recent years, WSNs have seen great development in design and applications. WSNs involve deployment of huge number of wireless sensor nodes essentially for monitoring certain area and collecting data and sent collecting data to the b...

Wireless Sensor Networks (WSNs) are used in many application areas including smart homes, military security applications, tracking applications and monitoring applications (oceans, animals, habitats). The number of these usage areas are increasing by day by. Currently, cyber attacks are a new battlefield and threat WSNs certainly. Protecting WSNs against attacks is an important topic and WSN ha...

Wireless sensors are currently widely applied in various industries. Wireless sensor networks (WSNs) are a type of infrastructure for smart factories in the Industry 4.0 era. Indoor deployment planning for WSNs is vital in three-dimensional (3D) plant spaces. Planning for WSN installation requires considering the following factors: (a) fault tolerance, (b) scalability, (c) cost, (d) hardware co...
