Abstract

A team of robots (also called actors) in Wireless Sensor and Actor Networks (WSANs) may not be able to optimally cover an area so that after an event is reported by a sensor all robots may not be quickly reachable for possible action in time. Furthermore, sensors may not be able to immediately deliver a report to a nearby robot. In this paper, we focus on dynamic location service to deal with sequence of multiple events in WSANs. We propose a novel dynamic mesh-based protocol (DMesh) to boost real-time performance of location service. We investigate new strategies for efficient event coverage, so that the robot team may appropriately partition, visit sensors periodically, and minimize reporting delay while preserving ability to respond possibly with increasing number of robots as event (such as a fire) progresses and more robots arrive near the scene.
基于动态网格的无线局域网机器人团队定位服务
无线传感器和参与者网络(wsan)中的机器人团队(也称为参与者)可能无法以最佳方式覆盖一个区域,因此在传感器报告事件后,所有机器人可能无法快速到达并及时采取可能的行动。此外,传感器可能无法立即将报告传递给附近的机器人。本文主要研究动态位置服务来处理无线局域网中的多个事件序列。为了提高定位服务的实时性,提出了一种新的动态网格协议(DMesh)。我们研究了有效事件覆盖的新策略,以便机器人团队可以适当地划分,定期访问传感器,并最大限度地减少报告延迟,同时随着事件(如火灾)的进展和更多机器人到达现场附近,保留机器人数量增加的可能响应能力。
