Wireless Sensor Network (WSN) localization is an important and fundamental problem that has received a lot of attention from the WSN research community. Determining the absolute and relative coordinate of sensor nodes in the network adds much more meaning to sense data. The research community is very rich in proposals to address this challenge in WSN. This paper, explores the various techniques...

Online monitoring and water quality analysis of lakes are urgently needed. A feasible and effective approach is to use a Wireless Sensor Network (WSN). Lake water environments, like other real world environments, present many changing and unpredictable situations. To ensure flexibility in such an environment, the WSN node has to be prepared to deal with varying situations. This paper presents a...

Majority of potential wireless sensor network (WSN) users have no formal education in computer science. To make WSN application development more feasible and attractive to this target audience, we have designed and implemented SEAL, a domain-specific language for WSN application description. Our idea is based on the observation that even though the lowlevel details of WSN are swarming with comp...

Research in Wireless Sensor Networks (WSN) necessarily touches on many research topics of Computer Science, Electronic Engineering and Telecommunication, basing on the existing work in related fields. However, the peculiarity of the WSN field is the interplay and integration of these foundation subjects, yielding a distinct topic worthy of further study in its own right. One of the main open is...

This paper describes an autonomous deployment and restoration of a Wireless Sensor Network (WSN) using mobile robots. The authors have been developing an information-gathering system using mobile robots and WSNs in underground spaces in post-disaster environments. In our system, mobile robots carry wireless sensor nodes (SN) and deploy them into the environment while measuring Received Signal S...

Optimal sensor deployment is necessary condition in homogeneous and heterogeneous wireless sensor network. Effective deployment of sensor nodes is a major point of concern as performance and lifetime of any WSN. Proposed sensor deployment in WSN explore every sensor node sends its data to the nearest sink node of the WSN. In addition to that system proposes a hexagonal cell based sensor deploym...

CoojaTrace extends the Cooja WSN-Simulator by offering extensive logging capabilities for debugging and analyses of multi-node WSN deployments. This is implemented using Scala-based Functional Reactive Programming (FRP)-techniques, enabling flexible and easily programmable in-depth access to the internal node, as well as simulator execution state. CoojaTrace is part of the DryRun framework; a s...

Wireless Sensor Networks (WSN) are worthy to use in ubiquitous healthcare environments. They provide comfort to patients and make patient monitoring systems more efficient. WSN, when applied in ubiquitous healthcare environments, have different characteristics and security requirements. Number of sensors is very small as compared to other WSN applications and all nodes are close to each other i...

The nature of Wireless Sensor Networks (WSN) and the widespread using WSN introduce many security threats attacks. An effective Intrusion Detection System (IDS) should be used to detect Detecting such an attack is challenging, especially detection Denial Service (DoS) Machine learning classification techniques have been as approach for DoS detection. This paper conducted experiment Waikato Envi...

This paper presents a survey on the current state-of-the-art in Wireless Sensor Network (WSN) Operating Systems (OSs). In recent years, WSNs have received tremendous attention in the research community, with applications in battlefields, industrial process monitoring, home automation, and environmental monitoring, to name but a few. A WSN is a highly dynamic network because nodes die due to sev...
