Lower Bounds from Tile Covers for the Channel Assignment Problem
نویسندگان
چکیده
A method to generate lower bounds for the channel assignment problem is given. The method is based on the reduction of the channel assignment problem to a problem of covering the demand in a cellular network by pre-assigned blocks of cells, called tiles. This tile cover approach is applied to networks with a cosite constraint and two different constraints between cells. New bounds are derived using this method, which lead to improved results when applied to an example from the literature.

Robust Quadratic Assignment Problem with Uncertain Locations
We consider a generalization of the classical quadratic assignment problem, where coordinates of locations are uncertain and only upper and lower bounds are known for each coordinate. We develop a mixed integer linear programming model as a robust counterpart of the proposed uncertain model. A key challenge is that, since the uncertain model involves nonlinear objective function of the ...
متن کاملAn Interval Assignment Problem with Multiple Attributes: A DEA-Based Approach
One of the basic combinatorial optimization problems is the assignment problem that deals with assigning jobs to individuals. In traditional assignment problems, n jobs usually assign to n individuals such that the total cost is minimized or the total profit is maximized. However, in numerous real-life applications, various attributes could be considered in assignment problems while data (obj...
متن کاملUpper and Lower Bounds of a Class of Channel Assignment Problems in Cellular Networks
A cellular network is often modelled as a graph and the channel assignment problem is formulated as a coloring problem of the graph. In this pape< we introduce the notion of cellular graphs that models the hexagonal cell structures of a cellular network. Exploiting the regular structure of the cellular graphs we compute the upper and the lower bounds for a class of channel assignment problems. ...

In recent years a new type of wireless networks named wireless mesh networks has drawn the attention of researchers. In order to increase the capacity of mesh network, nodes are equipped with multiple radios tuned on multiple channels emerging multi radio multi channel wireless mesh networks. Therefore, the main challenge of these networks is how to properly assign the channels to the radios. O...
متن کاملCapacity Bounds and High-SNR Capacity of the Additive Exponential Noise Channel With Additive Exponential Interference
Communication in the presence of a priori known interference at the encoder has gained great interest because of its many practical applications. In this paper, additive exponential noise channel with additive exponential interference (AENC-AEI) known non-causally at the transmitter is introduced as a new variant of such communication scenarios. First, it is shown that the additive Gaussian ch...
