Minimizing Energy Consumption in Wireless Sensor Networks Using Multi-hop Relay Stations
Sensor nodes usually operate by using limited energy sources. In order to achieve efficient energy utilization in Wireless Sensor Networks (WSNs), we need an effective network design approach. This paper presents a study of the optimal network design for minimizing energy consumption in continuous datagathering WSNs. We model the network design problem as an integer linear programming. Our key ...
متن کاملRateless Coding over Wireless Relay Networks Using Amplify/Decode and Forward Relays
In this paper two different rateless transmissionschemes are developed. In the proposed scheme, relay node candecode and forward the message to the destination if they areable to decode it, or amplify and forward the message to thedestination. Based on the analysis and simulation resultsprovided in this paper, the proposed method has bettertransmission time than the scheme which only the relay ...
متن کاملRelay Selection Based Space-Time Coding for Two-Way Wireless Relay Networks Using Digital Network Coding
In this paper, we propose a novel decode-and-forward dual-relay selection technique based on Alamouti space time coding for twoway wireless relay networks (TWRNs). The twoand the threephase TWRN protocol are used in the first and second version of the proposed technique, respectively, to exchange the information symbols of the communicating terminals. In order not to waste any power for transmi...
متن کاملCross-layer network lifetime optimisation considering transmit and signal processing power in wireless sensor networks
Abstract: Maintaining high energy efficiency is essential for increasing the lifetime of wireless sensor networks (WSNs), where the battery of the sensor nodes cannot be routinely replaced. Nevertheless, the energy budget of the WSN strictly relies on the communication parameters, where the choice of both the transmit power as well as of the modulation and coding schemes (MCSs) plays a signific...
متن کاملCapacity Bounds and Power Allocation for the Wireless Relay Channel
This paper studies upper bounds and lower bounds on the outage capacity and ergodic capacity of a three-node wireless relay channel in a Rayleigh fading environment. We also take into account practical constraints on the transmission duplexing at the relay node and on the synchronization between the source node and the relay node. We find that the gap between the upper bounds and lower bounds i...
