Mobile phone sensing is a new paradigm which takes advantage of the pervasive smartphones to collect and analyze data beyond scale what was previously possible. In mobile system, platform recruits smartphone users provide service. Existing applications systems lack good incentive mechanisms that can attract more user participation. To address this issue, we design for sensing. We consider two system models: platform-centric model where provides reward shared by participating users,...
The throughput of wireless networks can be significantly improved by multi-channel communications compared with single-channel since the use multiple channels reduce interference influence.

Different channel assignments lead to different network topologies. We present a novel definition co-channel interference. Based on...

We present a novel time-based positioning scheme (TPS) for efficient location discovery in outdoor sensor networks. TPS relies on TDoA (time-difference-of-arrival) of RF signals measured locally at to detect range differences from the three base stations. These are averaged over multiple beacon intervals before they combined estimate through trilateration. A nice feature this is that it purely localized: sensors independently compute their positions. statistical analysis performance noisy...
