Even though there is a increasing number of algorithmic methods for WSNs, the vast majority has never been tried in practice; conversely, many practical challenges are still awaiting efficient algorithmic solutions. The main cause for this discrepancy is the fact that programming

Selective Reprogramming of Mobile Sensor Networks through Social Community Detectionces is updated frequently, as scientists acquire in-field data and refine their hypotheses. Wireless reprogramming is therefore fundamental to avoid the (expensive) re-collection of the devices. Moreover, the code carried by the monitored individuals often depends on their characteristics, e.g., the

Improving Sensornet Performance by Separating System Configuration from System Logic present Chi, a full-system configuration architecture that separates system logic from system configuration. Drawing from concepts in artificial intelligence, Chi allows full-system configuration that meets both changing application demands and changing environmental conditions. We show that config

Virtualising Testbeds to Support Large-Scale Reconfigurable Experimental Facilitiestool in support of this is a testbed composed of real hardware devices which increases the realism of evaluation. However, due to hardware costs the size and heterogeneity of these testbeds is usually limited. In addition, a testbed typically has a relatively static configuration in terms of its net

Mitigating the Effects of RF Interference through RSSI-Based Error Recoverymeasurable, temporal increase in RSSI. We investigate how the receiver can use this information to detect interference and, through temporal correlation, estimate the bit error positions in a corrupted packet. In an experimental study in two testbeds and several realistic BAN scenarios we show that

On the Mechanisms and Effects of Calibrating RSSI Measurements for 802.15.4 Radiosion, make extensive use of Received Signal Strength Indication (RSSI) measurements. In this paper we show that inaccuracies in the RSSI values reported by widely used 802.15.4 radios, such as the CC2420 and the AT86RF230, have profound impact on these protocols and applications. Furthermore, we expe
