Energy Efficiency in Wireless Sensor Networks: A Utility-Based Architecture

Category: Software and Web Development, Networking and Communications

Overview Wireless Sensor Networks (WSN) comprises a fast-developing research area with a vast spectrum of applications. A WSN design is influenced by many factors such as transmission errors, network topology and power consumption. Consequently, developing a WSN application introduces several implementation challenges. This paper describes a multi-criteria architecture in order to achieve energy-aware and consistent message forwarding over a WSN. Using the proposed architecture a Directed Acyclic Graph (DAG) is formed throughout the WSN. Such DAG is used for multi-source data aggregation to a single sink. Intermediate nodes evaluate their energy reserve and induced error and decide whether message retransmission is needed.
