Increasing transmission power is an effective way to improve real-time data delivery in wireless sensor networks. On the other hand, increased power will also incur more interference though it can improve the link quality to increase real-time communication. So there is a tradeoff between interference and delay. In this paper, we consider a joint power control, scheduling and real-time routing problem,...
Wireless sensor networks (WSNs) usually work under harsh environment, so high packet loss rate is induced by the unreliable and error-prone wireless links. To cope with the problem, a competition and cooperation based reliable forwarding protocol (CCRF) is proposed. In CCRF, the characteristic of dense deployment of sensor nodes and broadcast feature of the wireless channel in WSN are utilized. Specifically,...
In this paper, we propose an energy-balanced cross-layer multi-path routing algorithm for wireless Ad hoc networks. This algorithm utilizes cross-layer information of the network nodes and can balance the energy consumption of the network nodes in flow distribution under the situation that the network topology is maintained unchanged; moreover, the transmission power can be adjusted in routing process...
