In this paper, we propose an improved MANET gateway selection scheme suitable for disaster recovery applications. Having an infrastructure less and decentralize features, MANET is well suited to bring the network back that has been collapse after a disaster. In this paper, we focus on improving throughput performance of MANET by designing a better gateway selection scheme. The key idea is to eliminate...
An Integrated Internet MANET is a heterogeneous networking architecture which is formed by interconnecting wired Internet with wireless MANET. Such architecture is needed in order to realize the potential of, and to achieve the stated objectives of proposed 5G networks of the future. Several issues arise in Integrated Internet MANET, chief among them being Quality of Service (QoS). Packet type based...
Integrated Internet-MANET (IIM) architecture is a hybrid network which is an interconnection of the wired Internet and wireless MANET. This interconnection is facilitated through gateways. Some of the important issues in this integration are gateway discovery and gateway load balancing. So far, these issues have been addressed separately in the literature. The issues of gateway load balancing and...
Gateway discovery algorithm is a fundamental protocol for interconnecting mobile ad hoc network (MANET) with the Internet. In most existing schemes, each gateway node broadcasts gateway advertisements to announce its presence. The decision of when to emit advertisements can influence the performance of the network. Traditional gateway discovery schemes adopt the method of periodically emitting advertisements...
An interconnection of mobile ad hoc network and wired Internet is called Integrated Internet-MANET. This interconnection is achieved through gateways. There are two very important issues in Integrated Internet-MANET. First, path load balancing in the communication of mobile nodes with gateways. Second, mobile nodes register with a gateway before communication begins. This registration is achieved...
The Internet architecture lacks natural support for contentcentric applications, which are dominating Internet usage today. This led to the design and development of a plethora of application-specific and incompatible solutions for content distribution, e.g., content-delivery networks and peer-to-peer. More recently, information-centric architectures have been proposed to address the root causes of...
Looking for usable gateway is a process, which brings the biggest overhead, in MANET accessing Internet. For controlling the routing overhead effectively, a gateway discovery method for MANET accessing Internet based on overhead control, which is according to the similar between ant searching path and mobile node searching gateway, is proposed in this paper. By simulating the pheromone's update process...
With the popularization of Internet and formation of wireless technologies provide significant impact on Internet and Communication Technologies. These technologies have support of one of famous technique known as Adhoc Network. Adhoc Networks are assortment of mobile nodes connected by wireless links and also receiving attention in the scientific community. In adhoc networks, routes may be disconnected...
There is no doubt that networks are becoming increasingly heterogeneous and future internetworks will likely interconnect different types of networks including wired, infrastructure-based wireless as well as infrastructure-less wireless networks, a.k.a., multi-hop mobile ad-hoc networks (or MANETs). Integrating MANETs to infrastructure-based networks (wired or wireless) allows network coverage to...
The Internet of Things is a rather new concept in IT field. The However, the research of routing protocols of Internet of Things is still a blank, while route designing is an important part in the research of Internet of Things. In this method, we designed a routing method that can take function as routing destination not just nodes. The improvement is more suitable for the use in internet of things,...
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...
The advancements of diverse radio technologies and emerging applications have spawned increasing heterogeneity in mobile ad hoc networks (MANETs). But the collaborative nature of communications and operations often requires that these heterogeneous MANETs to be interoperable. Nonetheless, the existing interconnection protocols designed for the Internet (namely inter-domain routing protocol such as...
In a practical ad hoc network scene where routing attacks are deployed, attackers are likely to be located in specific geographical region, which is likely to cause different influence on network performance. Though many simulations works has been done on sorting out different kinds of attacks, little work has been focused on the potential link between the severity of attack and the deployment of...
Mobile Ad-hoc Networks (MANETs) allow wireless nodes to form a network without requiring a fixed Infrastructure Dynamic Source Routing (DSR) for mobile Ad Hoc network. It is a reactive source routing protocol for mobile IP network. Temporally-Ordered Routing Algorithm (TORA) routing protocol is for mobile ad hoc networks. It can be made to operate in both reactive and proactive modes. It uses IMEP...
Mobile Ad-Hoc Networks (MANETS) will play a significant role in future tactical military networks. Tactical networks are required to support military operations in areas without access to a fixed network infrastructure. They are also characterized by frequent changes in network topology due to node mobility and intermittent line-of-sight (LOS) connectivity. The self-forming and self-healing nature...
Reliable and secure content distribution in a disruptive environment is a critical challenge due to high mobile and lossy channels. Traditional IP networking and wireless protocols tend to perform poorly. In this paper, we propose Content Centric Networking (CCN) for emergency wireless ad hoc environments. CCN is a novel communication architecture capable to access and retrieve content by name. This...
In cluster cache based k-hop clustered MANET routing protocol (CCBRP), cluster heads cache the information of remote clusters obtained during a route discovery process. When a remote destination is cached by a cluster head, RREP can be send to source directly by cluster head. By this way, the cost of route discovery is decreased. Route caches are maintained by cluster head and re-routing is minimized...
As MANET has characteristics like multi-hop wireless connection, dynamic topology, and limited bandwidth, its routing protocol faces great challenges.

This paper presents an adaptive scheme for gateway discovery in MANETs connected to the Internet. Basically, the proposed scheme reduces the flooding processes related to gateway discovery. To do so, the algorithm dynamically adjusts the interval of emission of the gateway advertisement messages to the need for updated routes to the gateway. The tuning is supported by the analysis of the spatial distribution...
