This paper proposes a topology control algorithm for wireless sensor networks which have a large scale structure and densely distributed nodes. One of the main problems in topology control is power efficiency with consideration of connectivity. The proposed algorithm is aimed to find a topology with near optimum power consumption within reasonable(More)
This paper proposes a topology control algorithm for Ad-Hoc networks which have a large scale structure and widely distributed nodes. One of the main problems in topology control is power efficiency with consideration of connectivity. The proposed algorithm is aimed to find a topology with near optimum power consumption within reasonable convergence time.(More)
In this article, the concept of linearity number (LN) is introduced to measure the “linearity” of the equations of motion of a serial manipulator. This number is computable in closed-form and is an average quantitative index of the degree of linearity of the robot over a specified region in the joint space. The definition is flexible, allowing the user to(More)
