LBCP：一种负载均衡的蓝牙无线传感网数据汇聚传输协议

在蓝牙分散网中，桥节点的数量和每个桥节点的度是影响数据汇聚传输协议性能的重要因素。在新的分散网结构基础上提出一种新的负载均衡汇聚传输协议-LBCP。该结构利用生长树主干节点间剩余的连接将树改造成网，在桥节点数量不变的情况下提高了桥节点的度，该协议根据一跳范围内的信息交换对数据流进行分流，实现了动态的负载均衡。仿真试验的结果表明，该协议在主干节点数量、数据到达率和数据传输速率等方面具有优势。

Bluetooth-Based Load-Balancing Convergecast Protocol for Wireless Sensor Networks

In a Bluetooth scatternet, the number of bridges and the degree of each bridge are significant factors that determine the performance of convergecast. In this paper, we propose a new load balance convergecast protocol (LBCP) based on a new scatternet structure, which is derived from the tree structure by adding spare links among its branch nodes. The new structure increases the degree of but without changing the number of bridges. The new protocol realizes dynamic load balance through diverting network traffic according to one hop info exchange. Simulation results show that the proposed protocol has prominent predominance on aspects of the number of bridge nodes, data arrival ratio and transmission band rate.
