EN The development of network functionalities in urban environment is accompanied by the emergence of new publicly available data sources. They are the basis of introduced research architecture and environment which was used to investigate new multicast algorithms proposed in this paper. These message-oriented algorithms are primarily intended to meet the needs of opportunistic routing in heterogeneous urban sensor networks. Although, due to their generalized and protocol-agnostic design, they can be of use in other network applications and research areas. Uncontrolled mobile relay devices are the key elements of presented delay tolerant multicast framework. Multicast structures are modeled in four Polish cities based on open data on the location of public transportation vehicles and elements of urban infrastructure. Over 16 thousand graphs were build and analyzed. It has been shown that the use of uncontrolled mobile relay enables the construction of time-spanning time-changing multicast structures. Their features are determined by the topology of given city area, the distribution of destination nodes, as well as, the number and the routes of mobile relay nodes. Efficacy and efficiency of the algorithms depend on radio range of the nodes, maximum time-span of forwarded messages, and network structure knowledge availability.
