Handling inelastic traffic in wireless sensor networks
The capabilities of sensor networking devices are increasing at a rapid pace. It is therefore not impractical to assume that future sensing operations will involve real time (inelastic) traffic, such as audio and video surveillance, which have strict bandwidth constraints. This in turn implies that future sensor networks will have to cater for a mix of elastic (having no bandwidth constraint requirements) and inelastic traffic. Current state of the art rate control protocols for wireless sensor networks, are however designed with focus on elastic traffic. In this work, by adapting a recently developed theory of utilityproportional rate control for wired networks to a wireless setting, we present a mathematical framework that gives us elegant queue backpressure-based algorithms. This allows us to design the firstever rate control protocol that can efficiently handle a mix of elastic and inelastic traffic in a wireless sensor network. The simplicity of our queue backpressure-based algori...
