我们提出了几何广播传感器和演员网络（GBSA），异构无线传感器和演员网络的一种新的广播协议。虽然广播是一种非常耗能的协议，但它也被广泛用作各种其他网络层协议的构建块。因此，通过优化广播来降低能耗是异构传感器网络的一个重大改进。GBSA是一种分布式算法，其中节点基于几何方法对是否发送进行本地决策。GBSA不需要任何邻域信息，并且施加非常低的通信开销。GBSA是可扩展的网络规模，节点类型，节点密度和拓扑结构的变化。GBSA无缝地适应这样的网络变化，包括在异构传感器网络中的演员的存在。实际上，GBSA利用了参与者节点，并在可能的情况下使用它们的资源，从而减少了传感器节点的能量消耗。通过模拟评估，我们表明，GBSA是非常可扩展的，其性能得到改善的演员的存在。据我们所知，GBSA是第一个专门为异构传感器和演员网络设计的广播协议。
We present geometric broadcast for sensor and actor networks (GBSA), a novel broadcasting protocol for heterogeneous wireless sensor and actor networks. While broadcasting is a very energy-expensive protocol, it is also widely used as a building block for a variety of other network layer protocols. Therefore, reducing the energy consumption by optimizing broadcasting is a major improvement in heterogenous sensor networking. GBSA is a distributed algorithm where nodes make local decisions on whether to transmit based on a geometric approach. GBSA does not need any neighborhood information and imposes very low communication overhead. GBSA is scalable to the change in network size, node type, node density and topology. GBSA accommodates seamlessly such network changes, including the presence of actors in heterogeneous sensor networks. Indeed GBSA takes advantage of actor nodes, and uses their resources when possible, thus reducing the energy consumption by sensor nodes. Through simulation evaluations, we show that GBSA is very scalable and its performance is improved by the presence of actors. At best of our knowledge, GBSA is the first broadcast protocol designed specifically for heterogeneous sensor and actor networks.
