Constructing minimum-interference networks
A wireless ad-hoc network can be represented as a graph in which the nodes represent wireless devices, and the links represent pairs of nodes that communicate directly by means of radio signals. The interference caused by a link between two nodes u and v can be defined as the number of other nodes that may be disturbed by the signals exchanged by u and v. Given the position of the nodes in the ...
متن کاملConstructing interference-minimal networks
We consider the problem of producing interferenceminimal graphs with additional properties such as connectivity, bounded stretch factor or bounded link diameter. We compute exact interference-minimal graphs and estimated interference-minimal graphs. The latter can be computed faster.
متن کاملConstructing Minimum Connected Dominating Set in Mobile Ad Hoc Networks
One of the most important challenges of a Mobile Ad Hoc Network (MANET) is to ensure efficient routing among its nodes. A Connected Dominating Set (CDS) is a widely used concept by many protocols for broadcasting and routing in MANETs. Those existing protocols require significant message overhead in construction of CDS. In this paper, we propose a simple, inexpensive and novel algorithm of comp...
متن کاملInterference in Cellular Networks: The Minimum Membership Set Cover Problem
The infrastructure for mobile distributed tasks is often formed by cellular networks. One of the major issues in such networks is interference. In this paper we tackle interference reduction by suitable assignment of transmission power levels to base stations. This task is formalized introducing the Minimum Membership Set Cover combinatorial optimization problem. On the one hand we prove that i...
متن کاملMinimum Total Node Interference in Wireless Sensor Networks
The approach of using topology control to reduce interference in wireless sensor networks has attracted attention of many researchers. There are several definitions of interference in the literature. In a wireless sensor network, the interference at a node may be caused by an edge that is transmitting data [16], or it occurs because the node itself is within the transmission range of another [2...
