Location service provides location information of robots to sensors, to enable event reporting. Existing protocols apply partial flooding to trace robots, leading to poor scalability. We propose a novel scalable location service, which applies hierarchical rings to update robot location and guide routing toward it. Each mobile robot creates a set of hierarchical update rings of doubling radii. Whenever...
Object tracking is one of the most important applications of WSNs, especially for military usage. Sensor nodes should collect information about intruders and sound alarms to military in good time. Previous protocols suffer from flooding based method or focus on tree-based approaches. We proposed a quorum based protocol that is suitable for multi-sink and multi-object tracking applications. Simulation...
Location service provides position of mobile destination to source node to enable geo-routing. Previous location service protocols suffer from partial flooding overhead, and/or location failures in group movement scenarios. To overcome those deficiencies, we propose a quorum-based location service. The basic idea is that destination node registers its location along a `column' to form an update quorum...
