Joint Routing, MAC, and Link layer Optimization in Sensor Networks with Energy Constraints
Joint Routing MAC Link layer
2015/6/19
We consider sensor networks where energy is a limited resource so that energy consumption must be minimized while satisfying given throughput requirements. Moreover, energy consumption must take into ...

We consider sensor networks where energy is a limited resource so that energy consumption must be minimized while satisfying given throughput requirements. Moreover, energy consumption must take into ...
Cross-layer Energy and Delay Optimization in Small-scale Sensor Networks
Small-scale Sensor Networks Optimization
2015/6/19
The general joint design of the physical, MAC, and routing layers to minimize network energy consumption is complex and hard to solve. Heuristics to compute approximate solutions and high-complexity a...
Spectrum Leasing via Cooperation for Enhanced Physical-Layer Secrecy
Physical layer security secrecy capacity spectrum leasing Pareto boundary power gain region
2012/5/9
Spectrum leasing via cooperation refers to the possibility of primary users leasing a portion of the spectral resources to secondary users in exchange for cooperation. In the presence of an eavesdropp...
BOUNDARY LAYER ESTIMATION OF NONLINEAR ELLIPTIC EQUATION
Nonlinear singular perturbation boundar
2007/8/7
In this paper, we consider the nonlinear elliptic equation... The limit problem is |u|^s=f on \Omega, where 00, for n\leq 4. Let d(x,\Gamma) be the distance from x to \Omega, let |\Omega| denote the m...
Using the interpolation theory of a family of linear operators and the Sobolev spaces, we introduce a quantity J_∈~4(λ) which depicts the shape of the boundary layer, andthen analyze the boundary sing...
