Under the condition of a single link failure, a routing algorithm with differentiated reliability requirements based on hierarchy model (DRRH) is proposed by analyzing the optimal routing mechanism which satisfies the reliability requirements. Simulation results and analysis show that the DRRH algorithm is able to solve the routing problem based on the reliability constraint and has a lower average...
Wireless sensors have started being utilized for industrial application which is typical harsh environment due to complicated layout and plentiful stationary/moving obstacles. As two hot standards for wireless industrial, WiHART and ISA100.11a, both adopt the centralized wireless sensor network with mesh topology to enable the reliable monitoring of a variety of environments. This kind of network...
We study the problem of communication reliability of wireless networks in a fading environment based on the outage probability formulation. The exact expression for the disconnect probability, the probability that a transmission by a node is not received correctly by any other node in the network, is obtained for one and two dimensional random networks. We obtain the end-to-end reliability of multi-hop...
As communication networks play an important role in today's life, network reliability becomes more critical than ever. Traditionally, network reliability is measured by connectivity or traffic volume. However, most of performance degradation problems are correlated with routing dynamic and congestion. It is necessary to include the both routing dynamics and congestion into network reliability computation...
Probabilistic forwarding is one of the routing methods that neighbors are selected as the next hop according to probability. The probability calculation method is different for different forwarding methods. Our work is based on selective forwarding and the selective forwarding probability based on the node degree and link loss is presented to increase the reliability of selective forwarding. The effect...
