An interconnection of wired internet and mobile Adhoc network is called integrated internet MANET. This interconnection is achieved through gateways. Gateway may be a fixed gateway or mobile gateway. The gateway works as the router for all the nodes of the MANET through which all the incoming/outgoing packets are routed between the MANET and the internet. Discovery of the efficient internet gat...

As a kind of typical embedded system, MANET is a multi-hop self-configuring network with the topology changes dynamically. To model of the security, mobility, and dynamic changes of MANET, trust is used as a novel concept recently. In this paper, based on the classic fuzzy theory, the trust evaluation and the dynamic routing protocols for MANET are represented, to give the modeling of MANET wit...

Adhoc networks uses mobile nodes to communicate among itself in which it does not have any fixed infrastructure like access point or base station. Due to dynamic network topology MANET security is a challenging task. Most of the routing protocols in MANET assumes a cooperative environment for communication. But, in the presence of malicious nodes, providing security to MANET is critical issue. ...

While mobile ad-hoc networking (MANET) research has received a considerable attention in recent years, the majority of them have focused on single-tier (e.g., ground) and homogeneous (e.g., same radio for every node) MANET. Few have investigated the potential implications of multi-tier and heterogeneous natures of MANET on the design and performance of MANET protocols in a systematic manner. Fo...

MANET is a collection of mobile, decentralized, and self organized nodes. Securing MANET is a problem which adds more challenges on the research. This is because MANET properties make it harder to be secured than the other types of static networks. This paper objective is to summarize different types of attacks over MANET, and concerns with studying sleep deprivation attack. Therefore, this pap...

A MANET (mobile ad hoc network) is a self-configuring infrastructure-less network of mobile devices connected through a wireless medium. All the devices in MANET can move independently in any direction and frequently change its link to other devices. Each device can act as both a transmitter and receiver therefore MANET doesn't require a fixed network infrastructure. Self-configuring abili...

In this paper, we propose internetworking strategy of WLAN and MANET. Both WLAN and MANET are based on IEEE 802.11 for MAC layer protocol while they adopt different mode, such as infrastructure and ad-hoc. To support internetworking between different IEEE 802.11 modes, switching algorithm on mobile node is proposed. This algorithm is mainly affected by user’s preference, not only by signal stre...

Applications of Mobile Ad Hoc Networks (MANET) are increasing in practice; however, MANET is venerable to attacks due to its mobile and ad hoc natures. The security issue is becoming a major concern and bottle neck in the applications of MANET; therefore, selections of intrusion detection methods are especially important for MANET applications. In the current paper, an overview of existing IDS ...

A Mobile Ad-hoc network (MANET) is a self organizing and adaptive in nature. A MANET consists of a set of mobile participants who must communicate, collaborate, and interact to complete an assigned mission. The challenges of MANETs are to provide wireless, high-capacity, secure, and networked connectivity. Node mobility in MANET causes frequent changes of the network topology. Routing protocols...

Mobile ad hoc networks (MANET) are constructed by mobile nodes without access point. Since MANET has certain constraints, including power shortages, an unstable wireless environment and node mobility, more power-efficient and reliable routing protocols are needed. The OLSR protocol is an optimization of the classical link state algorithm. OLSR introduces an interesting concept, the multipoint r...
