Networking together hundreds or thousands of small and cheap wireless sensor nodes requires highly energy-aware communication protocols at each layer, and much research work has been done to address this issue. However, the time-varying nature of the wireless channel also has a significant influence on the communication energy consumption, and this has long been ignored in most existing state-of-the-art...
The single-source and single-sink (SSSS) topology, in wireless sensor networks, is defined as the network topology, where every node behaves as a relaying node except the single source and the single sink. We consider the problem of finding a joint optimal scheme with consideration of physical, medium access control (MAC), and network layers to maximize the network lifetime (NL) for the SSSS topology...
The multi-source and single-sink (MSSS) topology, in wireless sensor networks, is defined as the network topology, where all of nodes can gather, receive and transmit data to the sink. We consider the problem of finding the joint optimal scheme with consideration of physical, medium access control (MAC), and network layers to maximize the network lifetime (NL) for the MSSS topology in the energy-constrained...
