Routing in cognitive networks is a challenging problem due to the primary users' (PU) activities and mobility. Multipath routing is a general solution to improve reliability of connections. Existing multipath routing metrics for traditional wireless networks do not take into account PUs' activities. This work introduces a new routes selection metric for multipath routing in cognitive networks. Routes...
The selection of routes is an important issue in wireless networks when network coding is used. Existing research formulate network-coding-aware routing as a linear optimization program. However, deploying such method in real wireless networks is impractical. To solve this issue, in this paper, a practical network-coding aware routing protocol is proposed for unicast sessions in wireless networks...
In this paper, we propose a new quality link metric, interference and bandwidth adjusted ETX (IBETX) for wireless multi-hop networks. As MAC layer affects the link performance and consequently the route quality, the metric therefore, tackles the issue by achieving twofold MAC-awareness. Firstly, interference is calculated using cross-layered approach by sending probes to MAC layer. Secondly, the nominal...
We propose a novel routing protocol, RMR, for wireless tactical, high-mobility military networks that finds reliable routes through difficult terrains with possibly compromised regions. RMR uses an end-to-end reliability measure that includes both end-to-end connectivity as well as trustworthiness, and reactively discovers routes over spatial cells whose local reliability is proactively maintained...
Wireless protocols, for IEEE802.11a, provide multiple none-overlapping channels. In this paper, we present an integrated metric routing protocol for multi-channel network, called IMR. The metric of this protocol composes the channel status and node status. Simulation results show that this protocol improves network average throughput and decrease end to end delay efficiently.
In order to improve delivery ratio and reduce average delay and network cost in Delay and disruption Tolerant Network (DTN), This paper puts forward a domain based single copy routing algorithm (DBR) for BirdNet, which is a special DTN based on mobile sensor nodes installed on birds with GPS function enabled. In this algorithm, the GPS position information from the bird is used, to assign the mobile...
Recently, hybrid wireless self-organizing (HWSO) networks by spatial and ground communication devices has become the focus in future information networks. Due to the characteristics including open medium, dynamic topology, redundancy structure and distributed collaboration, traditional routing protocols in fixed and ad hoc networks cannot be directly used in HWSO network, so that the design of special...
Energy problem is very important for routing protocol in WIA-PA Networks since these nodes only rely on their limited battery supply in bad environment. It is not possible for people to replace batteries. So how to make well use of the limited power and delay the lifetime of the WIA-PA networks became the focus of the people. This paper introduces the WIA-PA criterion from the Wireless Industrial...
Most of the existing routing schemes for opportunistic forwarding either rely on a priori known topology information, or provide explicit protocol information in the data packet header. In this paper, we present a routing protocol for opportunistic forwarding that dynamically create candidate priority forwarding lists without the need for any explicit control information in data packet headers, and...
Efficient routing is a fundamental issue in multi-hop wireless ad hoc networks. In this paper, we study the limitation of traditional routing structure in multi-hop wireless ad hoc networks due to (a) the layered structure of a wireless protocol stack and (b) the lack of coordination between medium access control (MAC) and routing protocols. These limitations result in long processing delays in a...
On the basis of analyzing the principle and performance of routing protocol in intermittently connected wireless networks, an enhanced protocol, which was named Probabilistic Sequence Routing (PSR) was proposed. PSR chooses the next-hop node to forward packets according to the forward-probability, which was calculated by contact-frequency and contact-duration. Simulation results indicate that PSR...
The cognitive radio (CR) technology was proposed as a solution for the lack of wireless resources in an environment with a rapidly growing number of users. The CR advances the dynamic utilization of the licensed users' unused spectrum channels by secondary users. The paper looks into large CR networks by proposing two improved variants of IPSAG (IP Spectrum Aware Geographic routing algorithm). The...
Routing algorithm mainly focuses on routing method to ensure the connection between the sender and the receiver during each session is optimal and effective. It is very useful in packet transmission, especially in meeting the quality of service. Some traditional shortest path search algorithm (Width preferred search algorithm, Dijkstra algorithm) can solve the shortest path problem well within polynomial...
Wireless ad hoc networks are a type of wireless network that can be easily created without the need of network infrastructure or central administration. Unfortunately, wireless ad hoc networks suffer from some limitations related to the bandwidth leakage. So a proper data flow mechanism should be used to save the bandwidth consumption. So we proposed an XCAST based routing protocol (P-XCAST) to be...
In multi-hop wireless networks, we often encounter a situation where there are some candidate paths between source node S and destination node D, and have to choose a path from the candidates. Although ordinary routing protocols select paths with minimum hops, QoS (quality of service) routing protocols evaluate paths using measures of QoS, such as expected transmission count (ETX). In multi-hop wireless...
Multihop wireless mesh networks have emerged as the next generation in wireless network technology. This is due to the advantages provided by the mesh network technology. WMNs provides ease of installation, cost effective deployments, high level of scalability, wide coverage area and capacity, network flexibility and self-configuration capabilities. However, despite these advantages, many research...
Multi-hop wireless network MAC protocols typically sacrifice packet latency to achieve energy efficiency. Such delays may well increase due to routing protocol operation. For this reason it is imperative that we attempt to quantify the end-to-end delay and energy consumption when jointly using MAC and routing protocols. In order to coordinate the subproblems, cross-layer feedback mechanism is established...
Multi-radio multi-channel technology is a viable solution to increase the capacity of wireless mesh networks (WMNs). On the one hand, the interference can be reduced by tuning neighbouring nodes on different channels. On the other hand, multi-hop coordination schemes that exploit the presence of multiple radios can be deployed at the MAC layer. In this paper, we propose a novel cross-layer architecture...
Because of the instability of link quality, traditional network routing protocols, which are mainly based on the condition of "Best Path", can not work very well over wireless mesh networks. Forwarding packets along the "Best Path" may also induce load imbalance among nodes. This paper presents a novel routing protocol named HPRP (Hierarchical Probabilistic Routing Protocol) for...
