摘要
提出了在具有移动基站的无线传感器网络中的一种新的路由协议,该协议在基站移动时只需要在一个小的区域内更新基站的位置信息,因此既节省了传感器节点的能量,又使基站在移动过程中仍可保持与传感器节点的持续通信。理论分析和模拟研究表明,与全局更新基站位置信息的路由协议相比,该协议降低了基站位置信息更新的代价,减少了无线信道的冲突概率,减少了延迟,可适用于对延迟要求较高的大规模无线传感器网络。
This paper proposed a novel routing protocol in WSNs with mobile sinks-＂a local location update-based routing protocol （ALLUP）＂, ALLUP for short. When the sink node moves, it only needs to broadcast its location information within a local area rather than among the entire network. Both theoretical analysis and simulation studies showed that compared with existing protocols that need to update the sinks location information among the entire network, the proposed protocal consumed less energy and decreased the collisions in wireless transmissions, which can be used in large-scale WSNs.
