The deployment of Wireless Sensor Network(WSN) must be done with some kind of advanced techniques so that it can mitigate the energy constraints. An existing, clustered-based routing protocol known as Low-Energy Adaptive Clustering Hierarchy (LEACH) was studied, the outcome is an improved algorithm based on LEACH. The performance of these algorithms was studied through simulations using OMNeT++. In...
Wireless sensor networks (WSNs) have appealed to researchers due to their wide range of application areas such as target detection and tracking, environment monitoring, and tactical systems. For WSNs, various medium access control (MAC) protocols with different objectives have been proposed. Designing energy-efficient MAC protocols has a significant influence on the network lifetime in WSNs. However,...
Energy efficient transmission and bit allocation schemes are investigated in multi-source single-sink wireless sensor networks (WSN). For transmission in AWGN channels with path loss, this work shows that the overall energy consumption can be saved if each source transmits using its minimum power and cooperates with other sources in TDMA mode. From the source coding perspective, the Slepian-Wolf coding...
