Abstract
With the advances in wireless communication technology and artificial intelligence, robots are gradually being introduced as a part of our life. Similarly to most mobile devices, mobile robots suffer from handoff latency. This paper proposes TASPR, a Topology-Aware Surveillance Patrol Robot, which can integrate the robotic status and topology information to assist handoff between access points (APs). TASPR uses Topology-Aware Hand-Off Scheme (TAHOS) to find the most promising AP from a list of candidate APs. When TASPR decides to initiate a handoff procedure, it analyzes moving direction, received signal strength and topology information to filter out unnecessary scannings. Thus, TAHOS has less handoff latency compared to conventional handoff procedure and neighbor graph algorithm (NGA).
