This represents a serious problem for many routing protocols, which often depend on bidirectional links. Routing protocols that can use unidirectional links often induce a high overhead. To overcome this problem we introduced Unidirectional Link Triangle Routing, a routing protocol, which uses neighborhood information, gathered actively or passively, to route around unidirectional links. In this paper, we describe Unidirectional Link Triangle Routing in further detail and present additional evaluation results from different application scenarios.}, language = {en} } @inproceedings{SieberKarnapkeNolte, author = {Sieber, Andr{\´e} and Karnapke, Reinhardt and Nolte, J{\"o}rg}, title = {From Energy Accounting to Energy Management}, series = {13.

Mostly batteries are used, which are vulnerable to temperature and non-linear effects. Additionally, variations within the hardware or induced by the software make the prediction of the available and consumed energy a complicated task. To reach certain lifetime goals under these influences, online energy management is necessary. For a fine-grained management on the level of individual sub-tasks, it is necessary to know where in the system the energy is consumed. In this work, we extend our online energy accounting approach to enable online energy management. We present ways to control application and device behavior, and, thus, energy using energy budgets. First experiments yield promising results, reaching their lifetime goals while maintaining a high application quality.}, language = {en} } @inproceedings{BeyerLohsKarnapkeetal., author = {Beyer, Sandra and Lohs, Stefan and Karnapke, Reinhardt and Nolte, J{\"o}rg}, title = {Self-Stabilizing Aggregation- and Reduction-Structures for Wireless Sensor Networks}, series = {13.

Also, links are not stable over time, and routes become unusable often, resulting in a need for new routing protocols that can handle highly dynamic links and use unidirectional links to their advantage. In this paper, we present BuckshotDV, a routing protocol which is resilient against link fluctuations and uses the longer reach of unidirectional links to increase its performance.
