In fire fighting having prompt and reliable tracking and communication in case of emergency is of paramount importance. We developed an integrated positioning, sensing and communication platform for tracking first responders in urban fire fighting. A Quality of Service (QoS) enabled TDMA MAC (QT-MAC) was designed to provide a low latency and high reliability service for critical data transfer, as...
In order to improve reliability, feasibility, reducing duration of failure, the key is to improve reliability of system and control the time of Master-standby-switch process. This paper focuses on the two important processes of Cross-unit Master-standby-switch Technology, and Master-standby-switch process under the High-end router, and proposed Cross-unit Master-standby-switch Technology Model Based...
Quality of service support for MANETs is a challenging task due to dynamic topology and limited resources. The main purpose of QoS routing is to find a feasible path that has sufficient resources to satisfy the constraints. In this paper a novel QoS routing algorithm based on ant colony optimization is proposed. The proposed algorithm uses Ant-like agents to discover and maintain paths, that satisfy...
This work investigates a differentiated resilience scheme for anycasting flows in the context of an MPLS network. The proposed resilience scheme allows anycast flows to survive both link and server failures. Three classes of survivability are considered (dedicated protection, shared protection and restoration). The performance of the different traffic classes is examined through simulation. Performance...
Networks need to accommodate diverse applications with different quality-of-service (QoS) requirements. New ideas at the physical layer are being developed for this purpose, such as diversity embedded coding, which is a technique that combines high rates with high reliability. We address the problem of how to fully utilize different rate-reliability characteristics at the physical layer to support...
In this paper, we investigate the effect of different restoration sequence upon multiple failure recovery in multi-wavelength WDM networks. The major difference among these arrangements is on restoration speed and resource utilization. We develop heuristics to find restoration sequence for dynamic traffic demands with different quality of service requirements. Especially, we adopt the aggregate rerouting...
