Wireless devices such as sensors have increasingly more processing, storage, and networking capabilities, making wireless sensor networks (WSNs) get lots of attentions in recent years. In addition, the cost of sensors is constantly decreasing making it possible to use large quantities of these sensors in a wide variety of important applications in environmental, military, commercial, health care,...
Middleware can provide novel and practical approaches for enhancing Cyber-Physical Systems (CPS) application development processes and operations. This paper discusses the roles and advantages of using middleware to build CPS. In addition, the paper studies the required features needed in such middleware for development and operation of CPS.
A Linear Wireless Sensors Network (LSN) is a sensor network model used for monitoring linear structures such as oil, gas, and water pipelines. This type of network depends on the information sent from one node to another in a sequence. As a result, a failure or attack that occurs at any node may isolate some nodes from the network, which will affect the reliability of the entire network. In this situation,...
Routing protocols in mobile ad hoc and sensor networks discover usable multi-hop routes between source and destination nodes. However, some of the routes found and used may not be as reliable or trustable as expected. Thus, finding a trusted route is an important component for enhancing the security of communication. This paper presents a trust-based routing protocol for enhanced security of communication...

Many environmental, commercial, military, and structural monitoring applications of wireless sensor networks (WSNs) involve lining up the sensors in a linear form, and making a special class of these networks; we defined these in a previous paper as Linear Sensor Networks (LSNs), and provided a classification of the different types of LSNs. A multihop approach to routing the data from the individual...
Linear Wireless Sensor networks (LSN) are used to monitor long linear critical structures such as pipelines, rivers, railroads, international borders, and high power transmission cables. Due to the importance of these structures, the LSN must be designed with high reliability considerations. However, one of the main challenges of LSN design is the connection reliability among the nodes. Unlike in...
One of the main challenges of using Linear Wireless Sensor Networks (LSN) is the reliability of the connections among the nodes. Faults in a few contiguous nodes may cause the creation of holes which will result in dividing the network into multiple disconnected segments. As a result, sensor nodes that are located between holes may not be able to deliver their sensed information which negativity affects...
