The design of a trust management framework in a mobile ad hoc network and its various components to protect against different attacks has a significant impact upon the performance of the secure routing protocol which is meant to form the most reliable route for data delivery. Specifically, the current work focuses upon the impact of certain parameters specific to two components within the proposed...
In networks that operate during a long time, the routing protocol might have to be changed (in order to apply a routing protocol update, or to take into account a change in the routing metrics). A loop-free transition algorithm has to be used in order to perform the transition to the new routing protocol without generating transient routing loops. In this paper, we propose a loop-free transition algorithm...
One critical issue for routing in Mobile Ad-hoc Networks (MANET) is how to select reliable paths that can last as long as possible, The reliability of a path depends on the number of links and the reliability of each link constituting the path. In this paper we developed efficient routing metric prediction methods by predicting link stability using a probabilistic computation based on the normal-like...
In distance vector routing, each router maintains a vector (table) of least cost route to all other routers. This vector distance algorithm was the original ARPANET routing algorithm and also used in internet with the name routing information protocol (RIP). A distance-vector routing protocol requires that a router inform its neighbours of topology changes periodically. One problem with the distance...
Routing protocols in Vehicular Ad hoc Network (VANET) have drawn lots of attention in recent years, most existing research efforts focus on designing IP-based protocols. In this paper, we present a new routing protocol for VANET based on Named Data Network (NDN). We optimize the routing path by using a new distance metric in the protocol, avoiding the shortcomings of hop-count based metric. Moreover,...
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,...
In this paper, we propose a reliable and interference-aware routing protocol for underwater wireless sensor networks (UWSNs). Proposed protocol follows end-to-end path from source node to sink and selects next forwarder node of a data packet on the basis, having already established a path to sink. In this way, the problem of encounters void hole in depth based routing protocol is eliminated. Furthermore,...
Vehicular Adhoc Networks (VANETS) enable the vehicles to communicate with each other as well as with road side units. But developing an efficient routing for these networks potentially due to the large mobility and regular changes in these networks is a challenging job. In VANETS transmission links are at the risk of disconnection. Thus the development of the efficient routing mechanism is needed...
To support QoS for a multimedia traffic, IEEE 802.11e standard Enhanced distributed channel access (EDCA) has been proposed. However, the EDCA is more focused on providing quality of service(QoS) solution at the MAC layer, which is necessary, but perhaps not sufficient as the layered TCP stack architecture does not satisfy the QoS demands in ad hoc network. This is due to the fact that routing protocol...
Opportunistic Networks (Oppnets) are the recent evolution of Mobile Ad hoc Networks (MANETs), where an end to end path from the source to the destination does not exist, or exists for a very small amount of time. That is, the connections between the nodes are often intermittent, and the power of the nodes may go up or down. This paper aims at improving the forwarding strategy in the Epidemic routing...
Wireless Mesh Networks (WMNs) are ad-hoc networks where no infrastructure exists and where some of the participating nodes can also act as routers to forward traffic on behalf of others. WMNs have been proposed for various applications and can greatly vary in terms of size (from a handful of nodes to thousands) and complexity (static or mobile nodes, scarce or dense etc.). Efficient and robust IP...
Ambient Assisted Living (AAL) is a concept that seeks to provide most autonomy, security, and health services for elderly people offering technology solutions to them. When AAL applications are provided through the Internet, it is possible to create new applications involving the concept of Internet of Things (IoT). The AAL-IoT applications can be used to event detection (such as fall detection or...
In Opportunistic networks (OppNets), due to high mobility, short radio range, intermittent links, unstable topology, sparse connectivity, to name a few, routing is a very challenging task since it relies on cooperation between the nodes. This paper focuses on using the concept of centrality to alleviate this task. Unlike other nodes in the network, central nodes are those that are more likely to act...
A Mobile Ad-hoc Network is a flexible wireless network. The nodes also function as routers which determine and propagate the routing tables amongst their neighbours to ensure a destination can be reached in the network. Without the restraint of physical links, mobility is common, these connections are not necessarily constant, with nodes free to either leave or join the network. This paper presents...
A wormhole attack is a specific mechanism where two or more Autonomous Systems (ASes) coordinate to perform a black hole attack by exchanging secure BGP updates over a tunnel, signing route attestations for each other. Routing protocols generally choose route through a wormhole because it is, in general, the shortest route. This attack can redirect traffic through a chosen path that is compromised...
This paper presents Multipath-ChaMeLeon (MCML) as an update of the existing ChaMeLeon (CML) routing protocol. CML is a hybrid and adaptive protocol designed for Mobile Ad-Hoc Networks (MANETs), supporting emergency communications. M-CML adopts the attributes of the proactive Optimized Link State Protocol (OLSR) and extends it so as to implement a multipath routing approach based on the Expected Transmission...
A large number of routing protocols for Cognitive radio networks (CRNs) have been proposed recently, each based on different design goals, and evaluated in different scenarios, under different assumptions. In our previous work, we conducted the first extensive empirical performance study of routing protocols for CRNs-Coolest Path, SAMER, and CRP — under the same realistic set of assumptions. Our study...

The Neighborhood Area Network (NAN) is the portion of the AMI that enables two-way communication between electric, gas and water meters and City Utilities. Many companies are currently deploying wireless NAN architectures based on the IEEE 802.15.4g technology while the Routing Protocol for Low-Power and...
