Message Dissemination Technologies with Spatial and Temporal Periodicity in Mobile Opportunistic Networks(1/3)

Project Details


Sustainable resource provision amongst upgraded mobile nodes in a network enables mobile nodes for collaborating in network construction, message delivery and resource sharing, definitely introducing a non-classical mobile opportunistic network. Mobile opportunistic networking is a modern distributed network architecture: particularly, a system is based on unstructured organizations and supports transient communications without resorting to traditional connection-oriented routing paradigms. Mobile opportunistic networking technologies are believed to be suitable in use for many pragmatic application domains, e.g., battlefield communications, disaster response networks, delay/disruptive networks, vehicular ad hoc networks, and underwater acoustic networks. This sort of practical networks is characterized by fragile network topologies, uncertainty of node presence, high node mobility, and sporadic connections. Message dissemination in a network must depend on relay nodes that repeatedly forward messages to neighbor nodes that are encountered during their movements. Owing to the aspects of environmental affects in reality and network dynamics, however, it is difficult to guarantee the applicability and performance of message dissemination mechanisms. In response to critical circumstances above, a promising solution is essential for the design and development of mobile opportunistic message dissemination technologies, thereby being a vital research dimension.Our study in the literature and many practical traces finds that node mobility patterns impose a significant effect on message dissemination in mobile opportunistic networks. The behavior of node mobility, empirically, involves flash crowding, clustering and periodicity properties at spatial and/or temporal standpoints, as well as implicit symmetry between spatial and temporal relationships. Prospectively integrating appropriate node mobility models with temporal and spatial periodicities in mobile opportunistic networks would be much beneficial for message dissemination and service designs in highly dynamic and unreliable network environments. Therefore, this research project aims to develop new message dissemination and management techniques for mobile opportunistic networking. This project proposal comprises five parts, as follows. First, we will analyze the variance of temporal periodicity and then design a dynamic periodicity-aware message delivery scheme. Second, we will use a probabilistic space-time graph model to develop a periodic message delivery scheme. Third, we will design a message delivery scheme based on spatial-temporal periodic symmetry. Fourth, we will account for the ferry-aided effects and then design a cooperative-ferry-based delivery scheme. Finally, we will adopt the game theory for performance optimization on storage utilization among all nodes in a network system. In accordance with all above, our study will achieve a new node mobility reference with spatial and temporal periodicity, and a dedicated suite of message dissemination and management mechanisms in mobile opportunistic network environments.
