Cyber-physical networking for wireless mesh infrastructures

[摘要] This paper presents a novel approach for cyber-physical network control."Cyber-physical" refers to the inclusion of different parameters andinformation sources, ranging from physical sensors (e.g. energy,temperature, light) to conventional network information (bandwidth, delay,jitter, etc.) to logical data providers (inference systems, user profiles,spectrum usage databases). For a consistent processing, collected data isrepresented in a uniform way, analyzed, and provided to dedicated networkmanagement functions and network services, both internally and, through anaccording API, to third party services. Specifically, in this work, weoutline the design of sophisticated energy management functionalities for ahybrid wireless mesh network (WLAN for both backhaul traffic and access, GSMfor access only), disposing of autonomous energy supply, in this case solarpower. Energy consumption is optimized under the presumption of fluctuatingpower availability and considerable storage constraints, thus influencing,among others, handover and routing decisions. Moreover, advancedsituation-aware auto-configuration and self-adaptation mechanisms areintroduced for an autonomous operation of the network. The overall objectiveis to deploy a robust wireless access and backbone infrastructure withminimal operational cost and effective, cyber-physical control mechanisms,especially dedicated for rural or developing regions.
