This paper proposes a self-contained displacement estimation method based on a human biomechanical model to track the position of walking subjects in the global coordinate system without any additional supporting infrastructures. Expand

Fingerprint-based localization systems mainly utilize the received signal strength (RSS) to estimate the location of a receiver, and the localization accuracy depends largely on the number and placement of access points (APs). Expand

In this paper, we propose a dynamic association mechanism that takes load balancing, link quality and association oscillation avoidance into consideration. Expand

We use a statistical decision-making framework to optimally solve the privacy-preserving routing problem in wireless networks given some utility constraints assuming a powerful global adversary that uses the optimal maximuma-posteriori estimation strategy. Expand

A joint, per-packet admission control and routing algorithm is used to optimize data quality of packets received at the sink, while still respecting delay guarantees. Expand

In this paper, we consider the cooperative spectrum sensing problem for a cognitive radio (CR) mesh network. Expand
