Tenet An Architecture for Tiered Embedded Networks Ramesh Govindan Eddie Kohler Deborah Estrin Krishna Chintalapudi Om Gnawali Ramakrishna Gummadi Thanos Stathopoulos Fang Bian Sumit Rangwala Abstract ity arguments state where functionality should reside in a network Our arguments are modeled after the end toFuture large scale sensor network deployments will be end principle 15 which states how functionality should tiered with the motes providing dense sensing and a be placed in data communication networks We call our higher tier of 32 bit master nodes with more powerful principle radios providing increased overall network capacity In The Tenet Multi node data fusion functionthis paper we describe a functional architecture for wireality and complex application logic should be less sensor networks that leverages this structure to simimplemented only in a tier of relatively highplify the overall system Our Tenet architecture has the powered Stargate class nodes which we call nice property that the mote layer software is generic and masters The cost and complexity of implereusable and all application functionality resides in masmenting this functionality in motes outweighs ters the performance benefits of doing so 1 Introduction The tiered embedded networks built on this principle which we also call Tenets contain both small form factor motes and Stargate class masters Tiered organizations have been discussed before 20 our contribution is to simplify the architecture by explicitly limiting mote functionality Motes contain sensing and actuation functionality and enable infrastructure less instrumentation of physical spaces and artifacts while masters are free of energy constraints and provide increased network and computational capacity enabling large scale deployments All mote sensor data is routed to computational elements running on masters or users and databases attached to masters Motes are tasked by applications running on masters and can implement simple logical
