Determining End-to-End Delay Bounds in Heterogeneous Networks

We define a class of Guaranteed Rate (GR) scheduling algorithms. The GR class includes Virtual Clock, Packet-by-Packet Generalized Processor Sharing and Self-Clocked Fair Queuing. For networks that employ scheduling algorithms belonging to GR, we ...

To achieve better performance, we adopt a Heterogeneous Sensor Network (HSN) model. In many applications, the locations of some sensor nodes are controllable. In this paper, first we propose a novel density-varying deployment scheme for high-end sensors ...

Wireless sensor networks (WSNs) are receiving more popularity in mission critical and delay sensitive industrial applications because they offer low latency and reliable message transmission. In applications like gas leakage detection, monitoring of ...
