Adaptive 3-Dimensional Topology Control for Wireless Ad-Hoc Sensor Networks
Developing an adaptive 3-dimensional (3D) topology control algorithm is important because most wireless nodes are mobile and deployed in buildings. Moreover, in buildings, wireless link qualities and topologies change frequently due to various objects and the interference from other wireless devices. Previous topology control algorithms can suffer significant performance degradation because the...
متن کاملSecure Adaptive Topology Control for Wireless Ad-Hoc Sensor Networks
This paper presents a secure decentralized clustering algorithm for wireless ad-hoc sensor networks. The algorithm operates without a centralized controller, operates asynchronously, and does not require that the location of the sensors be known a priori. Based on the cluster-based topology, secure hierarchical communication protocols and dynamic quarantine strategies are introduced to defend a...
متن کاملEnergy-Efficient Topology Control for Wireless Ad Hoc Sensor Networks
Energy-saving is a critical issue in mobile computing. Given a set of hosts which forms a wireless ad hoc network and an initial energy for each host, this paper considers the topology control problem by tuning the transmission powers of hosts to control the structure of the network. The target topology includes 1-edge-, 1-vertex-, 2-edge-, and 2-vertex-connected graphs. The goal is to maximize...
متن کاملDynamic Energy Efficient Topology for Wireless Ad hoc Sensor Networks
Wireless Sensor Ad hoc Networks (WASNs) are self organizing, self-configuring and multi-hop wireless networks, in which each node communicates with other nodes directly or indirectly through intermediate nodes without any infrastructure. Besides these characteristics challenges like limited energy, dynamic topology, low bandwidth and security exists. The arrangement of nodes in WASN is called t...
متن کاملLow-Interference Topology Control for Wireless Ad Hoc Networks
Topology control has been well studied in wireless ad hoc networks. However, only a few topology control methods take into account the low interference as a goal of the methods. Some researchers tried to reduce the interference by lowering node energy consumption (i.e. by reducing the transmission power) or by devising low degree topology controls, but none of those protocols can guarantee low ...
