An exact algorithm for the min-power symmetric connectivity problem in wireless networks

چکیده
In this paper we consider the problem of assigning transmission powers to the nodes of a wireless network in such a way that all the nodes of the network are connected and the total power consumption is minimized. The problem, which in the literature is referred to as the minimum-power symmetric connectivity problem, can be used to implement the broadcasting structure with minimum power consumption. A mixed integer programming formulation is presented together with some new valid reinforcing inequalities. Computational results show the effectiveness of the novel solving approach we propose. More complex methods recently appeared in the literature are outperformed by our technique.

Representing a Model for Improving Connectivity and Power Dissipation in Wireless Networks Using Mobile Sensors
Wireless sensor networks are often located in areas where access to them is difficult or dangerous. Today, in wireless sensor networks, cluster-based routing protocols by dividing sensor nodes into distinct clusters and selecting local head-clusters to combine and send information of each cluster to the base station and balanced energy consumption by network nodes, get the best performance ...

Mobile sensor networks rely heavily on inter-sensor connectivity for collection of data. Nodes in these networks monitor different regions of an area of interest and collectively present a global overview of some monitored activities or phenomena. A failure of a sensor leads to loss of connectivity and may cause partitioning of the network into disjoint segments. A number of approaches have be...
متن کاملAn efficient symmetric polynomial-based key establishment protocol for wireless sensor networks
An essential requirement for providing secure services in wireless sensor networks is the ability to establish pairwise keys among sensors. Due to resource constraints on the sensors, the key establishment scheme should not create significant overhead. To date, several key establishment schemes have been proposed. Some of these have appropriate connectivity and resistance against key exposure, ...
متن کاملHybrid Key pre-distribution scheme for wireless sensor network based on combinatorial design
Key distribution is an important problem in wireless sensor networks where sensor nodesare randomly scattered in adversarial environments.Due to the random deployment of sensors, a list of keys must be pre-distributed to each sensor node before deployment. To establish a secure communication, two nodes must share common key from their key-rings. Otherwise, they can find a key- path in which ens...
