FICTC: fault-tolerance-and-interference-aware topology control for wireless multi-hop networks
K-connectivity-based topology control can improve fault-tolerant performance of multi-hop wireless networks. Existing algorithms mainly focused on preserving the same k-connectivity between any two nodes. However, in practical network deployments, the algorithms enforcing k-connectivity degrade network performance, when the topology requires heterogeneous nodal fault-tolerant requirements. In t...
متن کاملTopology control for fault-tolerant communication in wireless ad hoc networks
Fault-tolerant communication and energy efficiency are important requirements for future-generation wireless ad hoc networks, which are increasingly being considered also for critical application domains like embedded systems in automotive and aerospace. Topology control, which enables multi-hop communication between any two network nodes via a suitably constructed overlay network, is the prima...
متن کاملDistributed fault-tolerant topology control in wireless multi-hop networks
In wireless multi-hop and ad-hoc networks, minimizing power consumption and at the same time maintaining desired properties of the network topology is of prime importance. In this work, we present a distributed algorithm for assigning minimum possible power to all the nodes in a static wireless network such that the resultant network topology is k-connected. In this algorithm, a node collects t...
متن کاملPower Efficient Wireless Sensor Networks with Distributed Transmission-Induced Space Spreading
Distributed multi-transmission is proposed for power-efficient and fault-tolerant multi-hop wireless sensor networks where a signal can be received and transmitted by multiple sensors. Multi-transmission with scrambling has advantages of both space-spreading and diversity. Efficient and robust blind equalization algorithms are developed. Network power efficiency can be greatly enhanced. Fault-t...
متن کاملA multi-hop PSO based localization algorithm for wireless sensor networks
A sensor network consists of a large number of sensor nodes that are distributed in a large geographic environment to collect data. Localization is one of the key issues in wireless sensor network researches because it is important to determine the location of an event. On the other side, finding the location of a wireless sensor node by the Global Positioning System (GPS) is not appropriate du...
