“…A main architecture of WSN has a multilevel network topology with a large number of sensor nodes deployed within a geographic area, and often communicating to the external network through a gateway node. The information communication between the sensor nodes and the gateway node is a multihop architecture since the transmission range of Bluetooth devices is only 10 m. Typical WSN applications with such topology include: habitat monitoring [15], health monitoring [16], data collection [17] etc. In these applications, data transfers occur infrequently, with a few unpredictable bursts.…”

This study presents the enhanced Bluetree, a mesh topology scheme for Bluetooth scatternet formation. The scatternet formation algorithm includes two phases. In the first phase, a root node begins to create a conventional tree-shaped topology. To improve the network reliability of tree topology, a return connection mechanism is introduced in the second phase to generate more connection paths and to convert the tree-shape into a mesh-shaped topology. The mechanism contains two connection models including the 'slave/slave mesh' (SSM) and the 'master/slave mesh' (MSM) models. The SSM model builds a meshshaped topology by interconnecting more leaf nodes, whereas the MSM model connects additional intermediate nodes to establish the backbone connection in a mesh-shaped topology. Simulation results show that the enhanced Bluetree effectively improves the performance metrics, including the piconet efficiency, path length and end-to-end delay, beyond the Bluetree with more formation packets. As a result, the enhanced Bluetree not only builds a mesh-shaped topology that improves the network reliability but also generates an efficient network with less packet delay performance than a conventional Bluetree network.

Blueweb is a self-organizing Bluetooth-based multihop network equipped with a scatternet formation algorithm and a hybrid routing protocol. Blueweb uses a designated root node to initiate scatternet formation and two mechanisms are introduced. One is the role exchange mechanism in which only slave nodes serve as the role of relay through the whole scatternet. The other one is the return connection mechanism in which we convert the scatternet from a tree-shaped to a web-shaped topology. In this paper, a variant-hop algorithm in forming Bluetooth sensor scatternet is proposed. Based on the design of Blueweb, this algorithm is a tier-based method to determine new roots and each new root spontaneously generates their individual web-shaped subnets. The heuristic method describes the variant-hop algorithms. With a constant k, a counter variable v, and return variable r as parameters, the variant-hop algorithm generates appropriate roots locally and evenly configures the subnet size. Computer simulation shows that this method achieves good network scalability and generates an efficient scatternet configuration for Bluetooth-based multihop sensor networks.

Blueweb is a self-organizing Bluetooth-based multihop network equipped with a scatternet formation algorithm and a hybrid routing protocol. The routing protocol combines the reactive method globally and the proactive method locally to discover the optimal path for packet transmission. In Blueweb, the route master maintains the global topology information and each master maintains its own N-tier routing information. In this paper, a tier number decision algorithm is used in Blueweb to determine the optimal number of tiers for all the other masters. Our computer simulation results show that this algorithm can efficiently improve the routing performance and reduce the routing maintenance cost for Blueweb routing protocol.
