Roads, streets and the heavy traffic emerged in metropolises are places where people spend a considerable amount of time. These are locations where lack of presence of the social‐inspired networks and services and also the presence of new opportunities that could be offered to the people are clearly evident. Undoubtedly, the absence of a proper infrastructure is one of the major barriers to create and deliver social application for vehicular scenarios. In this study, we focus on the idea of establishing a dynamic vehicular network to manage the social groups and the information of social applications. In order to achieve this goal, this paper presents a three‐layered network architecture with a middleware at its core. The middleware manages social groups and handles pivotal functions of information management and dissemination. The design principles and patterns used enable our strategy to disseminate the information quickly and extensively using different communication schemes. Through this approach, we evaluate this infrastructure based on groups with common spatio‐temporal properties and analysing the constant speed mobility in our data dissemination scheme.

“…If errors occur, this packet will be dropped by the receiver. A fountain code decoder tries to recover the source packets from the received encoded packets after accumulating a sufficient number of correct encoded packets, usually this sufficient number is slightly higher than K, an additional overhead of about 5 − 10% of K is typically required [11]. As users with different conditions have different packet loss rate, they need different transmission time to receive a sufficient number of packets and decode the message.…”

Multicast is an efficient way to support emerging multimedia services over wireless network. Fountain codes are used in multicast systems to enable a robust transmission without CSI feedback and ARQ. We propose a cooperative multicast scheme based on fountain code to improve the performance of multicast. The users are coordinated with each other to decode the message at different time slots within the data transmission of a multicast session. Specifically, we take the local channel state information (CSI) and the local residual energy information (REI) into consideration, and apply a relay-selection and power-allocation strategy in our cooperative multicast scheme to prolong the network lifetime, while keeping the transmission delay as low as possible. The simulation results show that the proposed scheme can achieve a good tradeoff between transmission delay and network lifetime.

Digital Fountain, which is widely used as practical forward error correction (FEC) solution, has been applied in many single-way broadcast communication systems. In this paper, we propose a novel feedback scheme for Luby Transform (LT) codes. The proposed modified LT coding scheme significantly reduces the number of encoded symbols, which are needed at the decoder to recover all input symbols. It is proved that the suggested scheme is very well suited to broadcast systems. Then we propose two algorithms which are named All Random (AR) and Levelly Search (LS) algorithms which can be properly used in broadcast models. Simulation results show that the proposed scheme outperforms the traditional LT in both unicast and broadcast systems with limited feedback. And both the AR and LS algorithms are effective in reducing the total amount of encoded symbols.
