Mobile Ad hoc Network (MANET ) is a collection of independent wireless mobile nodes, which is deployable on the fly. This work addresses the critical problem of key distribution in MANET by mining the traffic in network layer to extract the meta-data patterns and utilize them as tokens in application layer. A simple, fault-tolerant, and scalable approach with no prerequisite is introduced. It explains...
Routing in mobile ad hoc networks (MANETs) is central to their proper functioning. Network dynamics make the routing a real challenging task. Although a host of studies has been reported in the literature evaluating the performance of proposed routing algorithms, a deeper insight reveals some residual malfunctioning: wall effects, looping and inconsistency. In this paper, we first unleash the cover...
A mobile ad hoc network (MANET) operates much depending on node's willingness to cooperate in the network. A node's misbehavior can have severe impact in overall network performance. One of the different kinds of misbehavior a node may exhibit is malicious packet dropping. In this paper, we focus on detecting and excluding nodes that misbehave by dropping some or all packets forwarded through them...
We present AIR (automatic incremental routing), a unified approach for scalable unicast and multicast routing in mobile ad hoc networks (MANET). In AIR, nodes run a distributed routing algorithm to assign prefix labels to themselves. The labels are assigned such that routing to unicast or multicast destinations is automatic, in that a route from any node to a destination is defined by the node's prefix...
Recent years, the mobile ad hoc networks (MANETs) research community has been very active. Thus, it is of growing importance to build distributed network applications on top of MANETs. DHT is known as a popular technique to build efficient distributed applications in the Internet. However, in MANETs, DHT needs to consider network traffics, moving of nodes and energy efficiency more carefully than...
Mobility of nodes and unreliability of wireless channel complicate the task of routing data in mobile ad hoc networks. Using multiple paths for routing instead of just one is an interesting approach to this problem, with the advantage of greater path availability at the cost of higher routing overhead. Existing multipath routing protocols generally involve the destination node in decisions about the...
Most location service approaches for mobile ad hoc network rely on one static server or number of mobile servers distributed over the network area. These approaches suffer from servers' failures which cause out-of-date information and hence, using expired location information of the service. In this paper, a solution of such failures is presented through an adaptive server availability mechanism....
Mobile ad hoc networks have a highly dynamic topology due to terminal mobility. Ad hoc routing protocols can cope with this mobility as they search for an alternative route when a currently-in-use path breaks. Despite of their ability to recover from path failures, the time elapsed until the route is reestablished deteriorates network performance. MANET routing protocols can detect link breakages...
In this paper, we propose a novel proactive routing protocol, referred to as potential management based proactive routing (PMPR), for mobile ad hoc networks. Unlike other proactive routing protocols, PMPR performs request based routing recovery for proactive route maintenance. When a node has lost the routing information, it attempts a local route recovery by broadcasting a request message to neighbor...
Multicast communication over mobile ad hoc networks becomes popular. Dependable and scalable multicast routing protocol is required for large mobile ad hoc networks, even though network size and node mobility continue to increase. However, the data packet delivery becomes less dependable due to radio interference and frequent route breaks as the hop count between the source node and the multicast...
Mobile ad hoc network consists of nodes with mobility thus resulting in frequent route breakage. Considering this problem, in this paper, we propose a novel routing algorithm which constrains the distance to next relay node to increase route life time in mobile ad hoc networks (MANET). By limiting the distance to next relay node, our algorithm lengthened route lifetime and enhanced the throughput...
In recent years, various types of ad hoc routing protocols have been studied in the mobile ad hoc networks. Specifically, the clustering hierarchical routing algorithms have been developed to increase the system performance. Hierarchical structure has inevitably brought some drawbacks, maintaining the hierarchical structure needs more complicated cluster heads selection algorithm, which may result...
The design of efficient and scalable routing protocols is a fundamental challenge in wireless ad-hoc networks. Compare to topology-based routing protocol, position-based routing is regarded as having better scalability and lower control overhead, since hosts do not need to maintain the routes to their destinations and periodically broadcast the routing control messages. Location service is the most...
MANET (mobile ad hoc network) is a mobile multi-hop, wireless self-organized distributed network. This paper introduces the concept and characteristics of MANET, gives a general survey of research on local repair for MANET and proposes a new local repair scheme based on link breaks in order to make up the deficiency of the existing local repair schemes. The improved local repair scheme concerns about...
We present an improved mobile ad hoc network on-demand routing protocol which based on AODV by controlling the broadcasting of RREQ information. This protocol analysis the lifetime of node when implementing routing discovery, and avoiding the unnecessary information sending efficiently. By compare AODV with IAODV in the same scenario, the new protocol is much better than AODV in terms of packet delivery...
Routing is the main research issue in the development of wireless mesh networks (WMNs). Many of the routing approaches have been borrowed from mobile ad hoc networks (MANETs) to achieve routing solutions in WMNs but are not ideal or optimal and do not utilize the characteristics of WMNs to their benefits. In this paper, we propose an improved hierarchical AODV routing protocol (IH-AODV), which exhibits...
For mobile ad hoc networks used in network-centric operations, there is a growing need for a systematic methodology for analyzing/predicting the performance of the network over the mission duration. With the advance in cognitive networking as a possible means of exploiting unused spectrum, there is now a growing need to study how to design a cognitive network using an automated methodology. In this...
Recent research has shown that existing TCP/IP protocol family is likely to exhibit poor performance in space communication networks. To deal with communication challenges in deep space, an architecture called interplanetary Ad hoc Network (IPAN) is envisioned to establish a communication infrastructure among planets, natural and artificial satellites, and various mission elements such as spacecrafts...
This paper aims at adding quality of services (QoS) extensions to the associativity based routing (ABR). The performance analysis of the ABR with QOS support is the same as ABR except for more computation on the intermediate nodes to comply with the QOS requirements and the size of the control messages will be varying. But the total number of operations performed and total number of messages exchange...
In the recent years, wireless technology has enjoyed a tremendous rise in popularity and usage, thus opening new fields of applications in the domain of networking. One such field concerns mobile ad hoc networks (MANETs) where the participating nodes do not rely on any existing network infrastructure. By definition, the nature of ad hoc networks is dynamically changing and they have a fully decentralized...
