Routing is one of the most important operations in wireless sensor networks (WSNs) as it
deals with data delivery to base stations. Routing attacks can cripple it easily and degrade …

Wireless sensor networks are vulnerable to a wide set of security attacks, including those
targeting the routing protocol functionality. The applicability of legacy security solutions is …

In this paper we propose redundancy management of heterogeneous wireless sensor
networks (HWSNs), utilizing multipath routing to answer user queries in the presence of …

Conventional cryptography methods alone are not adequate for secure routing in Wireless
Sensor Networks (WSNs). These networks are more vulnerable to security attacks due to …

In WSNs, failures are unavoidable due to the inhospitable environment and unattended
deployment. The node failure leads to disconnection from the network and causes network …

As the applications of wireless sensor networks proliferate, the efficiency in supporting large
sensor networks and offering security guarantees becomes an important requirement in the …

Abstract Secured Two Phase geographic Greedy Forwarding (SecuTPGF) is a greedy
geographic forwarding protocol. It is used for transmitting multimedia data streams in …

Conventional target tracking systems are based on powerful sensor nodes, capable of
detecting and locating a target in a large deployment area but most systems require high …

In WSN Sensor node closer to the sink will exhaust their limited energy more rapidly than
other sensor nodes, since they will have to forward huge data during multi hop transmission …

Security in sensor networks is one of the most relevant research topics in resource
constrained wireless devices and networks. Several attacks can be suffered in ad hoc and …
