Traffic Based Dynamic Routing for Wireless Sensor Networks

Free registration required

Executive Summary

Numerous routing protocols have been proposed for wireless sensor networks, each of which is highly optimized for a certain class of traffic, like real time, reliable sense and disseminate, network reprogramming, energy efficiency and so on. However, a typical deployment demands an arbitrary communication pattern that generates multiple traffic types simultaneously. Arguably, no single routing protocol can completely cater to a deployment's various flavors. In this paper, the authors propose a dynamic routing framework that can replace the traditional routing layer with a collection of routing decisions. They allow application packets to carry a two-bit preamble that uniquely describes the nature of communication sought for.
