With fully directional communications, nodes must track the positions of their neighbors so that communication with these neighbors is feasible when needed. Tracking process introduces an overhead, which increases with the number of discovered neighbors. The overhead can be reduced if nodes maintain only a subset of their neighbors; however, this may increase the length of paths between node pairs in the network. In this work, we study the tradeoffs between node degree and path stretch. We first design a topology control algorithm to optimize t ....etc

XTC: A Practical Topology Control Algorithm for Ad-Hoc Networks
Abstract: The XTC AD-HOC network topology control algorithm introduced shows three main advantages over previously proposed algorithms. First, it is extremely simple and strictly local. Second, it does not assume the network graph to be a unit disk graph; XTC proves correct also on general weighted network graphs. Third, the algorithm does not require availability of node position information. Instead, XTC operates with a general notion of order over the neighbors' page link quali ....etc

Abstract.
Heterogeneous wireless sensor network (heterogeneous WSN) consists of sensor nodes with different ability, such as different computing power and sensing range. Compared with homogeneous WSN, deployment and topology control are more complex in heterogeneous WSN. In this paper, a deployment and topology control method is presented for heterogeneous sensor nodes with different communication and sensing range. It is based on the irregular sensor model used to approximate the behavior of sensor nodes. Besides, a cost model is proposed t ....etc

topology construction algorithm for Bluetooth devices in which a piconet or a scatternet is assumed to be a dynamic network structure. A new node can join the scatternet or an existing node can shut down at any point of time, without affecting the rest of the topology. The algorithm works bottom up by first combining individual nodes into small piconets, the small piconets then joining to form larger piconets. Finally, the large piconets join to form a scatternet. All these operations are conducted in a way such that none of t ....etc

Bluetrees - Optimizing Topology Of BT-WPANâ„¢s

Abstract :

Bluetooth is an open specification for short-range wireless communication and networking mainly intended to be a cable replacement between portable and/or fixed electronic devices. The problem concerns the assignment of the roles of master and slave to each node so that the resulting MANET is connected. In this Seminar we have introduce two novel protocols for forming connected scatternets. In both cases, the resulting topology is termed a bluetree. We also address the proble ....etc

Mesh Topology

According to the San Francisco-based market research and consulting firm, Internet traffic will have reached 350,000 Terabytes per month as we pass into the new millennium. This is a significant milestone, as it indicates that data has already surpassed the voice network. To keep pace with seemingly insatiable demand for higher-speed access, a huge, complex, network-building process is beginning. Decisions made by network Architects today will have an immense impact on the future profitability, flexibility, and competitiveness ....etc
