Intermittently Connected Wireless Networks (ICWN) or Delay/Disruption Tolerant Networks (DTN), have attracted attention from researchers because of their inherent characteristics, including long latency, low data rate, and intermittent connectivity. Extensive research has been conducted on ICWN, including the architecture, and routing. However, few researchers have investigated the performance of...
In recent years, along with the increasing popularity of multi-hop wireless networks, there has been a growing demand in the coupling of these networks to external ones such as the Internet. As traffic destined for external networks increases, special attention is required not only in gateway selection, but also in optimized routing and scheduling in order to maximize the network performance. In this...
This paper is focused on the analysis of energy-aware multi hop routing metrics for wireless environments which integrate heterogeneous devices that are carried or owned by Internet end-users. The paper gives our own (initial) perspective on how network energy-savings may be improved by considering not only a single (sender) node perspective, but also the perspective of its potential successors when...
Delay tolerant networks (DTNs) are a special type of wireless mobile networks which may lack continuous network connectivity. Multicast is an important routing function that supports the distribution of data to a group of users, a service needed for many potential DTNs applications. While multicasting in the Internet and mobile ad hoc networks has been studied extensively, efficient multicasting in...
Wireless internet has become popular in recent years due to the tremendous growth in the number of mobile computing devices and high demand for continuous network connectivity regardless of physical locations. In this paper, we investigate the effects of routing protocols on the performance of Transmission Control Protocol (TCP) variants in multi-hop wireless networks. Through simulations we study...
Delay-Tolerant Networks(DTN) are wireless networks where disconnections may occur frequently due to node mobility, power outages and propagation phenomena. In order to achieve data delivery, store-and-forward protocols are used in DTN and routing protocols based on epidemic message dissemination has been proposed, such as Epidemic routing. Under Epidemic routing, packets can be completely delivered...
We model the multi-path routing with selfish nodes as an auction and provide a novel solution from the game-theoretical perspective. By adapting the idea of generalized second price (GSP) payment originating from Internet advertising business and developing pertinent policies for multi-hop networks, we design a mechanism that results in Nash equilibria rather than the traditional strategyproofness,...
In recent years wireless mesh networks have been deployed and grown in popularity in many metropolitan areas. The deployment of such networks has allowed clients to gain access to publicly available broadband networks. The lack of standards and support for multicasting over wireless mesh networks makes this area very challenging as well as providing much scope for improvement. For first time in this...
In the tactical Internet, inter-domain links consist mostly of unreliable and low bandwidth wireless links. To enable seamless routing across different Autonomous Systems (ASes), we propose an inter-domain Traffic Engineering (TE) scheme to reroute traffic when congestion occurs. There are two components for the TE scheme. First, a Traffic Splitting (TS) scheme is used for load balancing among parallel...
To avoid congestion caused by some nodes overloaded and mesh points (MPs) becoming bottleneck in wireless mesh networks (WMNs), this paper proposed a new routing protocol called CLDSR-LB (cross-layer dynamic source routing protocol with load balancing). In order to avoid nodes overloaded, CLDSR-LB utilizes the idea of multi-metric and cross-layer and selects an optimal route by estimating the residual...
Multi-radio wireless mesh networks (MR-WMNs) are being increasingly deployed to provide affordable Internet access on large residential areas. MR-WMNs allow the supported mesh clients (MCs) to access the Internet gateway by multi-hop packet forwarding over the mesh routers (MRs), which can be equipped with multiple radio interfaces. In such a scenario, the routing protocol should (i) decide the address...
A wireless mesh network (WMN) is expected to be a key enabler for next generation networking due to its infrastructure-less strengths such as scalability, costefficient rapid deployment, and long distance communications. To boost the strength of WMNs, it is required to balance loads among multiple gateways as well as mesh nodes. However, there have been only few practical and easily-implementable...
This paper evaluates our work of Scalable Proxy Mobile IPv6 (SPMIPv6) in a Wireless Mesh Network (WMN), which is a promising solution for ubiquitous Internet access and a wide range of applications. The aspects of scalability and signaling cost are evaluated respectively: the scalability is evaluated by numerical analysis while the signaling cost with respect to delay is evaluated by a virtualization-based...
Due to its wireless multi-hop feature, wireless mesh network (WMN)is prone to suffer from many attacks, such as denial of service attack(DoS). In the DoS attack, when extortionate high-load flows flood to individual mesh routers (MR), they can no longer provide normal services to innocent flows. An active cache based defense solution can detect the existence of attacking flows based on the frequency...
In a wireless mesh network, the traffic is aggregated at mesh router and most of them forwarded towards the Internet through GW (Internet gateway). Thus easily leads to a bottleneck for network performance at GW. Aimed to this problem ,we firstly treated the GW and mesh router as the alike node equivalently. Then used the logarithm-normal distribution model of shadow affect in wireless communication...
Wireless Mesh Network (WMN) is an emerging technology that has developed a lot these years. WMN has the feather of self-organization, distributed structure. The main topological characteristic of WMN is that there are only one or several node connecting to the infrastructure network as gateway and all other nodes connect to the gateway through the relay of the neighboring nodes, and then connect with...
Wireless mesh networks have been attracting many users in recent years to achieve a wide-area wireless environment with flexible-configuration and low-cost properties by connecting base stations (mesh nodes) with each other via wireless connections. When the wireless mesh networks are used as an infrastructure for Internet access, all network traffic from mobile nodes go through a gateway node which...
In this paper we consider multi-hop wireless mesh networks intended to provide Internet connectivity to both end users and hotspots. In such networks mechanisms for provisioning QoS for delay sensitive flows arise as an important topic. In this context, we focus on the non-bifurcated (single path) routing of such flows as a means of allowing all packets in any flow to receive uniformly controlled...
This paper addresses the problem of routing packets between any nodes in a wireless mesh network (WMN) equipped with a set of reference landmarks. These reference landmarks are pre-selected Internet gateways or special nodes that broadcast beacon messages periodically. WMN nodes are then assigned multiple gradient-based coordinates, which are heights relative to the landmarks. These multiple heights...
