This paper presents a Broadcast and Reliable Coverage based Efficient Recursive Routing (BRCER) in Large-Scale Wireless Sensor Networks for Event-Driven Applications with Mobile Sinks (MSs). For data routing in the network, the proposed protocol updates the connectivity list by using local broadcast and multicast announcement. Instead of broadcasting in the whole network, the local broadcasting is used to save sensor node energy which maximizes the battery lifetime of sensors. However, the multicast announcement provides the appropriate path whenever the event activities are performed by MSs. In addition, reliable communication connectivity among sensor nodes, which depends on the surrounding and the deployment of sensor nodes, is also our prime concern for better quality of service (QoS). The main focus of BRCER protocol is to timely route the data with proper load distribution in the network with reliable connectivity. Theoretical concept and simulation results further validate that BRCER protocol can withstand in worse environmental conditions with effective network performance.

本文提出了在大型无线传感器网络中基于广播和可靠覆盖的高效递归路由（BRCER），用于带有移动接收器（MS）的事件驱动应用。对于网络中的数据路由，建议的协议通过使用本地广播和多播公告来更新连接性列表。本地广播不是在整个网络中广播，而是用来节省传感器节点的能量，从而最大化传感器的电池寿命。但是，每当事件活动由MS执行时，多播通知就会提供适当的路径。另外，取决于传感器节点的周围和部署的传感器节点之间的可靠通信连接性也是我们对更好的服务质量（QoS）的主要关注。BRCER协议的主要重点是通过可靠的连接在网络中以适当的负载分布及时路由数据。理论概念和仿真结果进一步验证了BRCER协议可以在较差的环境条件下承受有效的网络性能。
