Directed diffusion: a scalable and robust communication paradigm for sensor networks
TLDR
This paper explores and evaluates the use of directed diffusion for a simple remote-surveillance sensor network and its implications for sensing, communication and computation.

Directed diffusion for wireless sensor networking
TLDR
The use of directed diffusion for a simple remote-surveillance sensor network analytically and experimentally indicates that directed diffusion can achieve significant energy savings and can outperform idealized traditional schemes (e.g., omniscient multicast) under the investigated scenarios.

GHT: a geographic hash table for data-centric storage
TLDR
This paper describes GHT, a Geographic Hash Table system for DCS on sensornets, and demonstrates that GHT is the preferable approach for the application workloads predicted, offers high data availability, and scales to large sensornet deployments, even when nodes fail or are mobile.

Geographical and Energy Aware Routing: a recursive data dissemination protocol for wireless sensor networks
Future sensor networks will be composed of a large number of densely deployed sensors/actuators. A key feature of such networks is that their nodes are untethered and unattended. Consequently, energy…
Next century challenges: scalable coordination in sensor networks
TLDR
This paper believes that localized algorithms (in which simple local node behavior achieves a desired global objective) may be necessary for sensor network coordination.

Understanding packet delivery performance in dense wireless sensor networks
TLDR
This paper reports on a systematic medium-scale measurement of packet delivery in three different environments: an indoor office building, a habitat with moderate foliage, and an open parking lot, which has interesting implications for the design and evaluation of routing and medium-access protocols for sensor networks.

Data-Centric Storage in Sensornets with GHT, a Geographic Hash Table
TLDR
GHT, a Geographic Hash Table system for DCS on sensornets, is described, and it is demonstrated that GHT is the preferable approach for the application workloads, analytically predict, offers high data availability, and scales to large sensornet deployments, even when nodes fail or are mobile.

Heuristics for Internet map discovery
TLDR
The design of these heuristics and the experiences with Mercator are described, some preliminary analysis of the resulting Internet map is presented, and novel mechanisms for resolving aliases are employed.

Diversity in smartphone usage
TLDR
A comprehensive study of smartphone use finds that qualitative similarities exist among users that facilitate the task of learning user behavior and demonstrates the value of adapting to user behavior in the context of a mechanism to predict future energy drain.

Energy-efficient rate-adaptive GPS-based positioning for smartphones
TLDR
RAPS is presented, rate-adaptive positioning system for smartphone applications, based on the observation that GPS is generally less accurate in urban areas, so it suffices to turn on GPS only as often as necessary to achieve this accuracy.
