This paper presents the porting activities related to a famous agent-based middleware (MW) for Wireless Sensor Networks (WSN), i.e. Agilla. After discussing main WSN-MW features, the paper describes in detail the procedure used to port such a MW from TinyOS 1.x to TinyOS 2.x. The porting has been successfully completed and then validated by means of several Agilla applications. The new code, called...
Wireless sensor networks (WSN) are used in many applications like environmental monitoring, infrastructure security, healthcare applications, and traffic control. The design issue of such applications must address related to challenges around WSN Characteristics on one hand and the applications on the other. Middleware is a software that provides a common platform for the heterogeneity in WSN, enabling...
Wireless Sensor and Actuator Networks (WSANs) are highly heterogeneous regarding hardware, software, and application requirements. Developing WSAN applications is a hard task, as it requires domain and network knowledge and there is a lack of methodologies, architectures, and patterns to help software developers with such task. Moreover, non-functional requirements play an essential role to ensure...
A Wireless Sensor Network (WSN) is typically deployed on a place in which no electric source is provided, meaning that its battery consumption is crucial. Applications for WSNs require implementations of complex operations like network administration. To simplify the development of these applications, several mobile agent middleware solutions have been proposed (e.g., Agilla). Applications for these...
Electronic devices and sensor networks have witnessed great advancements. Consequently, their limited resources (CPU, memory, bandwidth, and power) are becoming suitable to accommodate some of the enterprise networks solutions. One possible and effective solution is Middleware technology that is able to provide several advantages such as simplifying applications development, portability, scalability,...
RFID and WSN technologies are widely used in today's pervasive computing. In Wireless Sensor Networks, sensor nodes sense the physical environment and send the sensed data to the sink by multi-hops. WSN are used in many applications such as military and environment monitoring. In Radio Frequency Identification, a unique ID is assigned to a RFID tag which is associated with a real world object. RFID...
WSNs have gained increasing attention for monitoring various parameters of interest for a wide variety of applications, ranging from environmental conditions to healthcare. WSNs aimed at medical and healthcare applications are known as Wireless Body Area Network or WBANs. WSNs are very resource-constraint and mostly deployed in environments where physical access is difficult or impossible. WBANs however...
Wireless Sensor Networks are becoming one of the most successful choices for the development and deployment of a wide range of applications, from intelligent homes to environment monitoring. Nowadays, there is a growing demand for fast development of WSN applications that adapt at run-time to changes in the context, in the available resources, and also in user requirements. In this paper we present...
In this paper we describe the design and implementation of Sensomax, a novel agent-based middleware for wireless sensor networks (WSNs), which is written in Java and runs on networks of various Java-enabled embedded systems ranging from resource-constrained Sun Spot nodes to resource-rich Raspberry Pi boards. Programming WSNs tends to be a complex task for developers, as it requires detailed knowledge...
Wireless Sensor Networks are becoming one of the most successful choices for the development and deployment of applications in a range of scenarios, from intelligent homes to environment monitoring. Nowadays, there is a growing demand for programming large-scale wireless sensor networks. New programming paradigms should ease the task of building WSN applications that adapt at run-time to changes in...
Component Based Software Engineering has achieved notable success in supporting the development of wireless sensor network applications. However, contemporary component models provide poor support for modeling distributed interactions: either relying on inappropriate communication primitives or providing no support for distribution. This paper argues that providing support for distribution is a critical...
Human civilisation continues to be plagued by problems of crime and is often left defenceless and ill-equipped each time a natural disaster occurs. A Wireless Sensor Network (WSN) can be used to keep track of the ground situation in a crime scene or when a natural calamity occurs. Cloud computing can be utilised to enhance the capabilities of the sensors. We propose a system called Rescue and Crime...
Recently, various IT technologies are utilized to support crop growth management. In farming field, dynamic data analysis while moving is cost efficient tool to farmer. Unlike previous works that not support dynamic analysis, mobile devices need to acquire the most recent data from nearest sensor for efficient processing in mobile device. In this paper, we designed the dynamic crop field analysis...
Nowadays, Wireless Sensor Networks (WSN) are already a very important data source to obtain data about the environment. Thus, they are key to the creation of Cyber-Physical Systems (CPS). Given the popularity of P2P middle wares as a means to efficiently process information and distribute services, being able to integrate them to WSN's is an interesting proposal. JXTA is a widely used P2P middleware...
Wireless sensor network (WSN) consists of distributed sensor nodes in the remote locations and are used to measure the sensor data in remote locations.

Heterogeneity of nodes in Wireless Sensor Networks (WSN) is one of the challenges that can negatively affect the overall network capability due to potential mismatches in the data format and structures exchanged between nodes. All nodes in a network must be able to communicate similar data structures and also confirm to the same data exchanging model. However, WSN nodes have very limited resources...
