The intra-chip communication latency and power consumption become the main bottleneck of the development of multi-core processors. network-on-Chip(No C) paradigm is proposed to meet these stringent requirements. Since the wireless network interconnection can achieve high speed data transmission with low power consumption, this paper proposes a cellular NoC architecture based on multiple butterfly network coding clusters with low latency. Data packets and control packets are transmitted on the wireless channel and the wired channel, separately. We also design a Z-X-Y path routing algorithm to achieve the shortest routing. Experiment results prove that, compared with Mesh, the proposed architecture can achieve at least 8% average latency reduction with slight resource increment.

network coding is a technique used to improve both wired and wireless networks' throughput and provide reliable transmission. In network coding, original data packets can be encoded to an infinite number of coded packets. A subset of these coded packets is sufficient to decode the coded packets and retrieve the original data. In addition to providing reliable data transmission, network coding can be used as a lightweight security mechanism to protect data against eavesdroppers. An eavesdropper is not able to decode coded packets and retrieve original data unless it has access to a sufficient number of coded packets. In a data transmission application, transmitting more redundant packets increases the chance of delivering a sufficient number of coded packets to the destination. As a result, this increases the reliability of the data transmission. However, more redundant transmissions make the system more vulnerable to eavesdropper attacks because there is a higher chance that an eavesdropper will receive enough coded packets. In this work, we study network coding to provide reliable and secure data transmission schemes by performing a trade-off between the security and reliability of the data transmission. We formulate the problem as a mixed integer and linear programming problem, and we propose a linear programming approximation to solve it. We study the performance of our proposed methods through extensive simulations.

network coding can improve the information transmission rate, which is an effective technology to improve the performance of wireless relay network. Based on cooperative diversity and network coding, the paper propose a two-way communication system model of vehicle and study the three-slot amplification and forwarding network coding scheme with direct link. The optimal power allocation scheme is obtained by analyzing the optimal power allocation based on the system outage probability. We analyze the influence of distance, speed and time on the probability of interruption. Simulation results show that the power optimization scheme proposed in this paper can obtain a lower outage probability than the equal power allocation scheme.

This paper presents an energy-efficient solution to overcome packet loss in Wireless Sensor networks (WSNs) by adding seed-based Random Linear network coding to MQTT for Sensor networks (MQTT-SN). Whereas most sensors integrated in common WSN devices consume little energy, using the radio is costly. To increase battery lifetime, devices try to minimize their radio uptime, while still satisfy timeliness and reliability of delivered data. The proposed approach uses an optimized seed-based intrasession network coding scheme for Forward Error Correction to shorten the sensor node's radio uptime, reducing its power consumption. The presented approach is conform to the MQTT-SN specification and, thus, interoperable with existing systems. Since the implementation is based on the application layer, it is seamlessly deployable via Over-The-Air-Programming. The presented evaluation is based on collected traces from a real-world WSN deployment in the context of Precision Agriculture. Radio uptime and power consumption measurements in an experimental testbed confirm the achieved benefits.
