The future wireless mobile devices considered in this paper incorporate three key features: (1) Wireless Wide Area Network (WWAN) radios, (2) short-range high-data-rate Wireless Personal Area Network (WPAN) radios, and (3) large (>;100GB) amounts of on-board cache. Approaches for finding and exploiting knowledge of Social Networks to decrease spectrum congestion and network latency in networks...
In recent years, Mobile Ad hoc Networks (MANETs) are continuing to attract the attention for their potential use in several fields. Mobility and the absence of any fixed infrastructure make MANETs very attractive for mobility and rescue operations and time-critical applications. In this paper, we present the implementation and analysis of our implemented MANET testbed considering the Optimized Link...
The conventional Mobile Ad-hoc Network (MANET) is composed of mobile nodes without any infrastructure. But, emergent traffic such as disaster positioning by using wireless infrastructure is indeed required. Therefore, network deployment for ad-hoc would associate WiMax with WiFi which is called 802.16e MANET Environment in this paper. Based on the 802.16e MANET environment, we propose a novel Hierarchical...
Doing research on mobile ad hoc network (MANET) security involves several constraints, some of which are wireless environment's attributes, such as bandwidth and delay, and the correctness of network topology. Testing and evaluating using real wireless devices are costly and somehow impractical, so many tools have been developed in order to create media by which researchers can deeply investigate...
In recent years, wireless multi-hop networks such as ad hoc networks, sensor networks, and vehicular networks have been very important subject for research. Mobile Ad hoc Network (MANET) is a collection of wireless mobile terminals that are able to dynamically form a temporary network without any aid from fixed infrastructure or centralized administration. In this paper, we present the implementation...
In recent years, MANETs are continuing to attract the attention for their potential use in several fields such as military activities, rescue operations and time-critical applications. In this paper, we present the implementation and analysis of our implemented MANET testbed considering AODV and BATMAN protocols for wireless multi-hop networking. We investigate the effect of mobility and topology...
Much work has been done on routing in Ad-Hoc networks, but the proposed routing solutions only deal with the best effort data traffic. Connections with Quality of Service (QoS) requirements, such as voice channels with delay and bandwidth constraints, are not supported. The QoS routing has been receiving increasingly intensive attention, but searching for the shortest path with many metrics is an...
Mobile ad hoc network is an autonomous system of mobile nodes characterized by wireless links. A wireless Ad-hoc network consists of wireless nodes communicating without the need for a centralized administration, in which all nodes potentially contribute to the routing process. In this paper we design a fuzzy-based priority scheduler to determine the priority of the packets. We analyze packet scheduling...
A Mobile Ad-hoc Network (MANET) can be implemented anywhere where there is little or no communication infrastructure, or the existing infrastructure is inconvenient to use. Dynamic and distributed address management is required due to host mobility and lack of central administration in MANETs. Many address management schemes have been proposed for this type of network but these are not without their...
A semi-infrastructured ad hoc network is a wireless MANET subnetwork connected to a structured backbone network (LAN). This kind of network is becoming popular for low cost implementation and practicability issues. But the security is being considered as the major bottleneck of such semi-infrastructured Ad Hoc network. Uncontrolled access medium, dynamically changing topology, mobility of the hosts...
Energy efficient communication in mobile ad hoc networks (MANET) is a very stringent issue due to the power-constraint in each mobile node. Thus designing a suitable energy efficient multicast routing protocol for optimum use of existing power and to render good system performance simultaneously is a real challenge. In this paper, we proposed a routing algorithm for multicasting that ensures efficient...
Data broadcasting in a mobile ad-hoc network (MANET) is the main method of information dissemination in many applications, in particular for sending critical information to all hosts. Finding an optimal broadcast tree in such networks is a challenging task due to the broadcast storm problem. The aim of this work is to propose a new genetic model using a fitness function with the primary goal of finding...
In a mobile ad-hoc network, nodes cannot rely on any fixed infrastructure for routing purposes. Rather, they have to cooperate to achieve this objective. However, performing network functions consumes energy and other resources. Therefore, some network nodes may decide against cooperating with others; selfish nodes. Also security issues are more paramount in such networks even more so than in wired...
Biologically inspired networking paradigm introduces throughput gains in an adaptive and robust operation over the classical routing algorithms designed for mobile ad hoc networks (MANETs). However, this performance gain comes at the price of additional overhead as in the case of ant routing protocols. In this context, we present the Scented Node Protocol (SNP) to reduce the overhead requirement while...
Routing in mobile ad-hoc networks is a challenging task. This paper proposes MPG-TAR, trust-aware routing protocol based on the formation of trusted Mobile Process groups(MPG). MPG is a collection of processes or mobile nodes present in defined vicinity where they all lie within each other's radio transmission range. The trusted MPG groups formed in MPGTAR calculate trust based on the mobility rate,...
In real world obstacles are almost ubiquitous, especially in the emergency situations like battlefields and disaster area where the ad hoc network is usually deployed. But obstacles are not taken into account by most of the existing mobility models. This paper provides an obstacle mobility model that realistically represents the movements in obstacle environment. It suits the network deployment in...
Since network disconnection will happen more frequently in mobile ad hoc network with group mobility model, the routing strategy proposed in delay-tolerant network could be applied for it. However, most of the current delay-tolerant routing protocols are designed based on the entity mobility model, not on the group mobility model. Motivated by this, in this paper we have proposed a new routing scheme...
Communication networks have evolved tremendously over the past several decades, offering a multitude of services while becoming an essential critical infrastructure in our daily lives. Networks in general, and the Internet in particular face a number of challenges to normal operation, including attacks and large-scale disasters, as well as due to the characteristics of the mobile wireless communication...
A mobile Ad Hoc network (MANET) is made of mobile nodes connected to each other via wireless links. The nodes function both as routers and as host devices, so routing protocols are necessary. They generate additional stream of control packets - the overhead. It can be reduced by controlling the request and response zones of Ad Hoc network nodes. In this paper, the method for routing in MANET is proposed,...
In this paper, we propose a method to reduce the routing overhead in DSDV (Destination-Sequenced Distance-Vector) networks. The proposed method benefits from the nature of DSDV, such as loop-free and shortest routing path, but alleviates the problem of control message flooding when the network topology changes. Given a destination node in a DSDV network, there exists a spanning tree using the destination...
