This paper presents a general view of the target tracking in Wireless Sensor Networks (WSN) with proper deployment of it. Target tracking task in WSN can be more accurately and efficiently accomplished, given the circumstance where the WSN is more proper deployed, for example, the coverage with clearer border and less holes, sensors with less movement, and connectivity well preserved. To prove ...

Wireless sensor network (WSN) has been widely used in industrial technology, national defense, robotic system [1], medical and health field. But it is hedged about in various fields due to its security problem. Through the analysis of the characteristics of Bluetooth WSN and its security architecture, this paper gives out a security scheme for Bluetooth WSN including piconet and scatternet. Thi...

In recent years, Wireless Sensor Network (WSN) is employed in many application areas such as environmental monitoring, and battle field strategy planning. For many applications of WSN, security is an important requirement. However, security solutions in WSN differ from traditional networks due to resource limitation and computational constraints. This paper analyzes & compares five popular WSN ...

Wireless sensor network (WSN) is an infrastructure less, low cost, dynamic topology, appplication oriented, multihoping network design with small, low power, sensing wireless distributed nods. WSN designing become more complex due to characterstics of deploying nodes, security, authentication and its operation scenario. This paper presents an analytical view on WSN architecture design issues, i...

Telemedicine aided by wireless sensor networks (WSN) has recently become a healthcare trend. Many previous studies have adopted the ZigBee-based WSN to implement a platform and/or a telemedicine system. However, the low data rate and bandwidth have limited the maximum number of nodes in a WSN during continuous and simultaneous transmission. The issue of low data throughput has not been addresse...

Here, we present the collision probability of the IEEE 802.15.4 slotted Carrier Sense Multiple Access/Collision Avoidance (CSMA/CA) mechanism over a real-time wireless sensor network (RT-WSN), also called a synchronous network system. The “backoff,” the random delay of CSMA/CA, can be used to create a probability model and to determine the average packet delay over RT-WSN. The proposed theoreti...

Wireless Sensor Networks (WSN) are designed to collect large amounts of heterogeneous data to monitor environmental phenomenon. Our aim is to adapt WSN nodes communication to their context, in order to optimize the lifetime of the network. Our description of context and WSN characteristics are based on ontologies. Based upon a critical analysis of existing ontologies which formalize the WSN dom...

Wireless Sensor Network (WSN) is leading to a new paradigm of Internet of Everything (IoE). WSNs have a wide range of applications but are usually deployed in a particular application. However, the future of WSNs lies in the aggregation and allocation of resources, serving diverse applications. WSN virtualization by the middleware is an emerging concept that enables aggregation of multiple inde...
