Topology Control (TC) is one of the most important techniques used in wireless ad hoc and sensor networks to reduce energy consumption and radio interference, The goal of this technique is to control the topology of the graph representing the communication links between network nodes with the purpose of maintaining some global graph property (e.g., connectivity), while reducing energy consumption...
In this paper, a new distributed clustering algorithm for mobile ad hoc networks, named as DCCS (Distributed Clustering Algorithm Based on delta- Cluster Stability) is proposed. The cluster stability of node, which is defined in this paper, is applied to clustering for mobile ad hoc networks. This algorithm is implemented on the ns2 environment, and compared with classical Lowest-ID clustering algorithm...
In two recent contributions, we have provided a comparative analysis of various optimization algorithms, which can be used for atomic location estimation, and suggested an enhanced version of the Steepest Descent (ESD) algorithm, which we have shown to be competitive with other distributed localization algorithms in terms of estimation accuracy and numerical complexity. Moreover, therein we have conducted...
Collaborative working manner of individual satellite nodes demand totally distributed algorithms and protocols. The mobile nature of these nodes requires that these algorithms and protocols must be adaptive to the ceaseless topology changes. This paper proposes an adaptive decision making function and weight factor in a highly efficient algorithm for the distributed nodes, which helps solving the...
The goal of the sensor network localization problem is to determine positions of all sensor nodes in a network given certain pairwise noisy distance measurements and some anchor node positions. This paper describes a distributed localization algorithm based on second-order cone programming relaxation. We show that the sensor nodes can estimate their positions based on local information. Unlike previous...
