Modeling the Behavior of Wireless Linear Sensor Networks

Prof. Dr. Saad Talib Hasson Aljebori


Wireless sensor networks (WSNs) have been widely recognized as a promising technology that can enhance various aspects of infrastructure monitoring. WSNs are widely used in monitoring and tracking systems. Wireless sensor nodes are a key technology that is commonly applied in many useful real-world applications. WSN applications can be created by distributing a number of sensors in different deployment approaches. Most applications of wireless sensor networks require reliable and timely data communication with a maximum possible network lifetime under a low traffic regime. These requirements are very critical, especially for the stability of wireless sensor and actuator networks.

There are special environments that require specific network structures. In monitoring pipelines, bridges, tunnels, railways, border lines, and highways, a special class of WSN in which nodes are deployed in linear structures can be proposed to form a linear wireless sensor network (LWSN) that extends to a long distance area. In wireless sensor networks, node placement plays a significant role in terms of meeting design goals, such as cost effectiveness, connectivity, lifetime, and data latency. For example, in tunnel environments, the energy consumption of sensor nodes and relay nodes is imbalanced because of the long and narrow shape of tunnels.

WSNs can be deployed in different fields in order to provide online insights into the surroundings of the observed infrastructure. In some critical applications, WSN can form a linear or semi-linear network topology, which is called a Linear Wireless Sensor Network (LWSN). LWSN is one of the special classes of the network topology for WSNs. In addition, LWSNs have unique features such as long distance and narrow networks compared to other network topologies. In LWSN, sensor nodes are distributed in a linear structure with a narrow region along the network with a distance that reaches hundreds of kilometers. Therefore, it’s not possible to communicate with the sink in single hop form. Moreover, traffic generated by sensors far from the sink will have to use other nodes to transfer their generated traffic.

Therefore, data traffic will be delivered with a significant delay. The schemes for balancing energy in WSNS are not suitable for LWSN as nodes in LWSN have unique characteristics. Nodes near the sink deplete their energy quickly as they deal with heavy traffic compared with other nodes in the network. Load balancing between sensor nodes in LWSN is a challenge.

Engineering Application of Bioenergy Systems, Developments, and Challenges

Assoc. Prof. Dr. Obed Majeed Ali

Bioenergy is one of the most important research fields in meeting global future energy demands. This contribution can be extended significantly in the near future by reducing greenhouse gas emissions and saving the environment, as well as improving trade balances, contributing to energy security, and providing opportunities for the economic development of society in rural areas. Bioenergy is the only renewable source that can replace fossil fuels in all energy markets in the production of heat, electricity, and fuels for transport. Many bioenergy principles can be used to convert biomass feedstock into final bioenergy products. A wide variety of conversion technologies are under construction, with improved competence, lower costs, and improved environmental protection. However, the possible competition between raw materials for bioenergy and other biomass applications must be carefully considered. Logistics and infrastructure issues should be spoken off, and there is a need for further scientific innovations leading to more competent and cleaner conversion of more assorted feedstock.
