WISER/s: Policy-based Session Contorol Protocol in Multi-Robot Sensor Networks

of Master’s Thesis WISER/s: Policy-based Session Contorol Protocol in Multi-Robot Sensor Networks Recently there has been a great deal of research on using mobility in sensor networks to assist their sensing tasks. In this paper, we propose a modeling of policy-based session control for sparse multi-robot sensor networks (MRSNs) called WISER/s. In an MRSN, when a large volume of data or continuous data is required to be transferred, there exists a problem how the mobile robots are formed for carrying the data to the destination. To overcome this issue, we propose a suitable method of session control which is determined based on a state of surrounding mobile nodes such as number, maximum-velocity and buffer-size. WISER/s also takes a system policy of either delay minimization or energy efficiency into consideration. In this thesis, we describe the model and protocol of WISER/s. We also evaluate WISER/s by using mobile robots. Keyword: 1. Multi-Robot Sensor Networks, 2. Mobile Sensor Networks, 3. Session Protocol, 4. Networked Robots.
