Intro

This is a brief summary of "Routing Without Routes: The Backpressure Collection Protocol".

Background

Traditional routing protocols, such as link state or distance vector routing protocols work by explicitly calculating a route in the network from one node to another.

While these protocols work very well (as proven by the fact that they are deeply established in today's networks), they are not the "ideal" protocols for all network topologies. Specifically, they do not necessarily provide a globally optimum distribution of congestion in many-to-one transmission topologies, often leading to possible bottlenecks.

BCP is an implementation of Backpressure Routing - a completely different routing mechanism - for wireless sensor networks. BCP implements backpressure routing on wireless sensors to try to achieve the globally optimum distribution of traffic across the sensor network.
