The paper addresses the issue of self-adaptation of a multi-modal sensor network with mobile sensors to better observe and track events of interest in a changing urban scenario by presenting a software module (middleware) called Event-driven Network Controller (ENC) that resides at every sensor node in the network and is independent of the sensor type. ENC translates the requirements of the app...

Sybil attacks pose a serious threat for Wireless Sensor Networks (WSN) security. They can create problems in routing, voting schemes, decision making, distributed storage and sensor re-programming. In a Sybil attack, the attacker masquerades as multiple sensor identities that are actually controlled by one or a few existing attacker nodes. Sybil identities are fabricated out of stolen keys, obt...

Three dangerous attacks in wireless sensor network is handled in this proposed security solution. This paper proposes a lightweight and fast mobile agent technology based security solution against cloning attack, sinkhole attack and black hole attack for wireless sensor networks (WSNs).Recently mobile agents have been proposed in wireless sensor networks to reduce the communication cost especia...

In a wireless sensor network (WSN), node localization is key requirement for many applications. The concept of mobile anchor-based not new concept; however, the anchor nodes gains much attention with advancement in Internet Things (IoT) and electronic industry. this paper, we present range-free algorithm sensors three-dimensional (3D) networks based on flying anchors. nature also suitable vehic...

Large-scale mobile Underwater Wireless Sensor Network (UWSN) is a novel networking paradigm to explore aqueous environments. However, the characteristics of mobile UWSNs, such as low communication bandwidth, large propagation delay, floating node mobility, and high error probability, are significantly different from ground-based wireless sensor networks. The novel networking paradigm poses inte...

An architecture for large scale low power sensor network is proposed. Referred to as sensor networh with mobile agents (SENMA). SENMA exploit node redundancies by introducing mobile agents that communicate opportunistically with a largefreld of sensors. The addition of mobile agents shifIs computationally intensive t a s k awayfrom primitive sensors to more powerful mobile agents, which enables...
