In this paper we study the application of Diversity Coding to enable near-instantaneous recovery from link failures in 5G Centralized Radio Access Network (C-RAN) networks. We focus on networks where remote radio heads in a C-RAN are connected to the baseband unit with wireless fronthaul links. In order to avoid retransmissions and rerouting delays due to link failures, we investigate use Diversity...
On — chip communication suffer from bit error especially at highly dense implemented system on chip. Reducing the rate of bit error in On-chip communication is carried out by error detection and correction codes. But it has its own limitation. So reconfigurable multiple code based system is suitable for heterogeneous system design. But selecting correct code for the correct subsystem or for current...
With the further development and utilization of space resource, space communications nowadays are increasingly becoming irreplaceable networking technologies for highresolution earth observation, satellite navigation and deep space exploration where big data is produced. This has created great challenges in ensuring the security and reliability of some sensitive data. In order to solve some problems...
In this paper, we propose a Fragmentation-based Multipath Routing (FMR) model for Software Defined Networks (SDNs) to enable attack-resilient data transfer. With the use of erasure encoding to fragment a message, the fragments are routed along multiple paths such that no intermediate node receives enough fragments required for message decoding. This ensures that, any intruder on a compromised node...
This paper proposes KAR (Key-for-Any-Route), a new intra-domain resilient routing system in which edge-nodes set a route ID to select any existing route as an alternative to safely forward packets to their destination. In KAR routing system, a route is defined as the remainder of the division between a route ID and a set of switch IDs along the path(s) between a pair of nodes. KAR-enabled switches...
Wireless sensor networks are very much concerned on conserving power and error control coding is a considerable burden on this power conservation. Thus, this paper proposes a diversity based routing algorithm to achieve the reliability in the absence of error control coding. Two diversity combining techniques are also proposed. The simulation results demonstrate that the proposed routing algorithm...
Security issue occupies an important part in all communication system and especially for new generation networks. Among these networks, we find Delay Tolerant Mobile Networks (DTMNs) which are a class of useful but challenging networks. Combining Network Coding (NC) and clustering for routing in such networks gives more efficiency and copes with routing reliability problem among large scale networks...
The Wireless Sensor Converge-cast Networks (WSCNs) are widely applied in many fields such as medical applications and environmental monitoring. The monitoring data are collected from the sensors and gathering toward the sink node. A coding aware routing scheme based on Connected Dominating Set is provided. Based on CDS, a coding condition, named Improved Coding Conditions (ICC), is defined with an...
Two of the design criteria in wireless sensor networks (WSNs) are the security and reliability of information flow, especially in critical applications. In this research, we propose combining a Crypto-System with Embedded Error Control (CSEEC) with multi-path routing for secure and reliable communication in WSNs. CSEEC is a joint encryption and error correction scheme based on erasure coding. When...
In this paper we address the issues of timeliness and transmission reliability of existing industrial communication standards. We combine a Forward Error Correction coding scheme on the Medium Access Control layer with a lightweight routing protocol to form an IEEE 802.15.4-conformable solution, which can be implemented into already existing hardware without violating the standard. After laying the...
A Mobile Ad Hoc Network (MANET) is a dynamic wireless network that can be formed without the need for any pre-existing infrastructure in which each node can act as a router. Due to bandwidth constraint and dynamic topology of mobile ad hoc networks, multipath supported routing is a very important research issue. This paper proposes a Network Coding-based AOMDV routing algorithm in MANET (NC-AOMDV)...
Multicast is an important mechanism in modern wireless networks and has attracted significant efforts to improve its performance with different metrics including throughput, delay, energy efficiency, etc. Traditionally, an ideal loss-free channel model is widely used to facilitate routing protocol design. However, the quality of wireless links would be affected or even jeopardized by many factors...
Many routing protocols have been proposed for wireless sensor networks (WSNs). However, only few of them addressed secure routing. This work contributes in solving secure and reliable routing problems by presenting a secure and reliable multipath routing protocol (MSR) for WSNs. MSR consists of three key components: on-demand multipath routing, enhanced passive acknowledgment, and erasure coding....
The smart grid applications requires real time analysis, response within the order of milliseconds and high-reliability because of the mission critical structure of the power grid system. The only way to satisfy these requirements is in-network data analysis and built-in redundancy routing for failures. To achieve this, we propose a data dissemination system that builds routes using network flow algorithms,...
In order to improve the throughput and transmission reliability in wireless sensor network with limited resources, multicast network coding technology is imported in. On this basis, through random linear network coding by nodes' cooperation to make improvement in delayed and expense. The simulation results show that the transmission, to the opportunity routing, by cooperation network coding strategies...
The energy costs of transferring data from sources in Wireless Sensor Networks (WSNs) to sinks at the edge of the network are high. These high costs have generated much interest in data storage strategies within the WSN. The frequently dangerous and power limited conditions in which nodes are required to operate can however result in the loss of nodes that are vital data storage points. We extend...
Network coding scheme improves throughput and reliability in a Wireless Sensor Network. A straight forward broadcasting by flooding in a wireless sensor network is very costly and reduce the network coding benefit. The packet loss probability increases due to contention and collision which is referred as broadcast storm problem. In this paper, we have proposed a Network Coding based Probabilistic...
Network coding (NC) and erasure coding (EC) share a common principle of encoding incoming data packets at network intermediate nodes so that destination nodes can reconstruct the original data packets using a sufficient number of encoded data packets collected at the destinations. While NC in general reduces the number of packets sent through the network, EC introduces redundancy into the packet streams...
Routing is one of the most challenging open problems in Vehicular Ad hoc NETworks (VANETs) because of the short-lived wireless connectivity environment. Store-carry-and-forward approach using buses on regular routes is considered as one of the most promising emerging routing policy that can significantly improve delivery performance and reliability in VANETs. While none of existing solutions considers...
