Supporting mobility in wireless sensor networks is one of the major requirements for future Internet of Things (IoT) applications. This work focuses on optimizing the objective function of Routing Protocol for Low-power and Lossy Networks (RPL) in mobile applications. RPL routing is the most common standard routing protocol designed for IoT applications. We optimized RPL objective function by combining...
When two nodes in an opportunistic network meet, a utility function is generally employed to select the data that have to be exchanged between them, in order to maximize the chance of message delivery and to minimize congestion. The utility function computes weighted sums of various parameters, such as node centrality, similarity, trust, etc. Most of the existing solutions pre-compute the weights...
Mobile multimedia has today become a promising application for end users and service providers. With reference to the existing systems for mobile communications, this application further demands for solving several technical problems, especially regarding video streaming over wireless networks. An interesting approach is in form ofWireless Mesh Network (WMN) based networks, where the individual video...
This work describes a clean-slate inter-domain routing protocol designed to meet the needs of the future mobile Internet. In particular, we describe the edge-aware inter-domain routing (EIR) protocol which provides new abstractions of aggregated-nodes (aNodes) and virtual-links (vLinks) for expressing network topologies and edge network properties necessary to address next-generation mobility related...
Because of the feature of hybrid wireless mesh network, hybrid routing protocol is the most proper routing protocol for this kind of network. Hybrid routing protocol is composed of proactive routing protocol and reactive routing protocol. The proactive one is adaptive for static mesh routers, and the reactive one is suitable for mobile mesh clients. Existing hybrid routing protocols all neglect the...
The article aimed at offering new ways of routing in networks with the DTN architecture, which allows using the most optimal routes for determining the routes depending on various conditions. To achieve these goals, it is necessary to analyze the available developments in this field with the subsequent identification of advantages and disadvantages. An attempt to realize advantages with a minimum...
An examination of existing studies in the area of Routing Protocol for Low-Power and Lossy Networks (RPL) implementation in wireless sensor networks (WSNs) reveals a consistent approach taken of optimal node distribution. This in order to best evaluate networking metrics such as Packet Delivery Ratio (PDR), latency and energy consumption. The tests detailed in this paper differ from previous work,...
RPL is the routing protocol for low-power and lossy networks and has recently been considered as the standard routing protocol for IPv6 based wireless sensor networks using the IEEE 802.15.4 protocol. RPL is oriented towards supporting multi-point to point communications in which multiple points typically communicate with one sink node that considered the root of the RPL tree. RPL aims to minimize...
Mobile Opportunistic Network (MON) is a kind of Delay Tolerant Network (DTN) in which nodes are mobile with social characteristics. Users in such network carry data, move and forward it to others for information dissemination. There are already much work done on the routing problem in MON to achieve higher performance, they usually just focus on the physical contact among nodes and their social attributes,...
One of the main considerations in designing routing protocols for Mobile Ad-Hoc Network (MANET) is to increase network lifetime by minimizing nodes' energy consumption, since nodes are typically battery powered. Many proposals have been addressed to this problem; however, few papers consider a proactive protocol like Optimized Link State Routing Protocol (OLSR) to better manage the energy consumption...
Mobility is the most issues for the majority ofprotocols including the RPL (IPv6 Routing Protocol for LowPower and Lossy Networks). RPL a routing protocolstandardized by IETF is usually used in Internet of ThingsTechnology. It is proposed to support communications in Lowpower and Lossy Networks (LLNs). However, mobility limitsthe use of RPL protocol in realistic study. In this paper wehave classify...
Heterogeneous Wireless Mesh Networks (HetMesh) is a promising high throughput technology for multi-hop data forwarding by mobile clients and backbone routers in a dynamic environment. HetMesh supports Wifi-Direct facility and other separate access technologies in its mobile clients, which makes the selection of a suitable next hop forwarder for data transmission challenging. This paper proposes a...
With the increasing number of wireless mobile devices, the possibility of mobile communications without network infrastructure is becoming a reality. The decentralized mobile social network (MSN) is a paradigm where nodes can move freely and organize themselves arbitrarily. Therefore, the key challenge is to find routes that can provide satisfactory delivery performance and low average end-to-end...
Previously dominating research on the Internet Quality of Service (QoS), focused on network performance, has now been shifted towards the customer experience. This paper addresses Quality of Experience (QoE) management issues in the future Internet. We provide a brief overview of QoE metrics and assessment methodologies, and discuss potential relationships between the QoE and network performance parameters...
In MANETs, link failures are caused frequently due to node's mobility and use of unreliable wireless channels for data transmission. Multipath routing strategy can cope with the problem of the traffic overloads while balancing the network resource consumption. This article proposes an improved approach named DNDR (Dual Node-Disjoint Paths Routing) to enhance the network reliability and robustness...
Ad hoc communications are attracting more and more attention in today's research and technology, because of low cost implementation, and simple initialization procedures. They are being projected to be used in several fields such as collaborative computing and disaster recovery environments. However, route instabilities and scalability are issues that still need to be addressed. In this paper we implement...
Since traffic load in mobile networks typically changes significantly over time, time-varying routing, where routing changes in certain time intervals, seems an obvious solution. Yet multiple researchers have claimed independently in the past, that time-varying routing does not lead to worthwhile benefits given its overhead. In this paper, we study this issue in a systematic way. We argue that previous...
Social wireless and mobile networks have received more attentions over the recent years. Previously, we proposed the Social Relation Opportunistic Routing (SROR) algorithm for mobile social networks, and introduced the social relations and profiles among nodes as the key metrics to compute the optimal forwarding node in routing such that the packet delivery probability is maximized. In this paper,...
In mobile Multi-hop Cognitive radio network (CRN) routing is a challenging issue since Secondary users (SU) mobility and Primary user (PU) activity may cause radio links to break frequently. The stability and reliability of a route depends on the availability of the links constituting the route. In this paper, we propose a mobility aware stable routing scheme that considers the SUs mobility and the...
In this paper we examine mobile routing path stability performance when constrained to use a distributed connected dominating set (CDS) control plane induced sub graph. Weighted, degree-based Essential CDS (ECDS) results are presented alongside those obtained using a CDS temporal stabilization algorithm. Full topology shortest path forwarding (SPF) results are also presented as a comparison baseline...
