In a wireless sensor network, multiple nodes would send sensor readings to a base station for further processing. It is known that such a many-to-one communication is highly vulnerable to a sinkhole attack, where an intruder attracts surrounding nodes with unfaithful routing information, and then performs selective forwarding or alters the data passing through it. A sinkhole attack forms a seri...

Sinkholes are a well-known geologic hazard but their past occurrence, useful for subsidence risk prediction, is difficult to define, especially for ancient historic times. Consequently, our knowledge about Holocene carbonate landscapes is often limited. A multidisciplinary study of Trieste Karst (Italy), close to early Roman military fortifications, led to the identification of possible ancient...

Mobile ad-hoc network abbreviated as MANET is most emerging and highly demanding wireless network technology. Due to the property of self-deliberate, where all point of network behaves like source or router and also all nodes are keeps on moving freely in network area. Mobile ad hoc network perform important role in connectionless environment. Security is the most fundamental requirement in mob...

The wireless sensor networks are subjected to threats and highly vulnerable to various attacks due to the sensor characteristics, such as the openness of wireless communication channels, lack of infrastructure, and physical discloser. Sensor networks are highly susceptible to denial of service (DoS) attacks due to their inherent characteristics. Sinkhole attack is well-known routing attack in w...

Wireless Sensor Networks (WSNs) are used in many applications in military, ecological, and health-related areas. These applications often include the monitoring of sensitive information such as enemy movement on the battlefield or the location of personnel in a building. Security is therefore important in WSNs. However, WSNs suffer from many constraints, including low computation capability, sm...

In this paper, we present an Intrusion Detection System designed for wireless sensor networks and show how it can be configured to detect Sinkhole attacks. A Sinkhole attack forms a serious threat to sensor networks. We study in depth this attack by presenting how it can be launched in realistic networks that use the MintRoute protocol of TinyOS. MintRoute is the most widely used routing protoc...

A new Gammarus species is identified based on the specimens collected from Morca Sinkhole, which was discovered in 2019 Anamur District, South of Türkiye. Eleven individuals belonging to newly were siphon located at end sinkhole (-1260 m). The can be distinguished by following character combinations and morphological features: blind, colorless (unpigmented) completely setae-covered body. Setae ...

The outstanding geosites in Satun UNESCO Global Geopark, Thailand are mainly karst topography. Sinkhole which is originated from the dissolution of rocks by groundwater or acidic rainwater one potential natural disasters these geosites. To gain confident among geotourism, detecting features, cavities and surficial crucial risk assessment sustainable geopark management. As a part geohazard asses...

Physicochemical characterization, automated ribosomal intergenic spacer analysis (ARISA) community profiling, and 16S rRNA gene sequencing approaches were used to study bacterial communities inhabiting submerged Lake Huron sinkholes inundated with hypoxic, sulfate-rich groundwater. Photosynthetic cyanobacterial mats on the sediment surface were dominated by Phormidium autumnale, while deeper, o...
