PROJECT TITLE :

On the Delay Performance in a Large-Scale Wireless Sensor Network: Measurement, Analysis, and Implications

ABSTRACT:

We gift a comprehensive delay performance measurement and analysis in a massive-scale wireless sensor network. We tend to build a light-weight delay measurement system and present a strong method to calculate the per-packet delay. We show that the method can identify incorrect delays and recover them with a bounded error. Through analysis of delay and alternative system metrics, we have a tendency to get to answer the following fundamental queries: What are the spatial and temporal characteristics of delay performance in an exceedingly real network? What are the most vital impacting factors, and is there any sensible model to capture those factors? What are the implications to protocol styles? In this paper, we establish important factors from the data trace and show that the necessary factors don't seem to be essentially the same with those in the Internet. Furthermore, we have a tendency to propose a delay model to capture those factors. We revisit many prevalent protocol styles like Assortment Tree Protocol, opportunistic routing, and Dynamic Switching-based mostly Forwarding and show that our model and analysis are useful to practical protocol designs.
